Introduction

Several insect lineages developed camouflage-related traits. Stick insects (Phasmatodea) are remarkable among them presenting striking adaptations, such as a very elongate body, cryptic coloration and forelegs that when extended conceal the head (Bradler and Buckley 2018). Nevertheless, colorful or very robust forms are not rare. These less cryptic representatives usually present other defense mechanisms such as large spines or the capacity of spraying an irritating substance from the prothoracic gland, an organ typical of Phasmatodea (Bradler and Buckley 2018).

In the Neotropics, one of the world’s hotspots of Phasmatodea diversity, many of the colorful sprayer phasmids belong to the Pseudophasmatidae lineage (Brock et al. 2024). To date 325 species are described for this family (Brock et al. 2024), which is divided into three subfamilies, including Pseudophasmatinae containing around one third of that diversity. This group is further subdivided into the tribe Paraprisopodini Zompro, 2004, containing only a peculiar genus specialized in bark camouflage, the tribe Anisomorphini Redtenbacher, 1906 and the tribe Pseudophasmatini Kirby, 1904. While a proper delimitation of Anisomorphini and Pseudophasmatini is still pending, their type genera are easily distinguishable: Anisomorpha Gray, 1835 presents short and flattened subgenital plates for both sexes and Pseudophasma Kirby, 1896 presents longer, convex subgenital plates for both sexes with the male poculum strongly convex and bearing a lateral finger-like projection (Conle and Hennemann 2002). Species of these groups are able to spray a pungent, minty substance from the prothoracic glands and often display characteristic coloration patterns including lines, stains and contrasting tones. The coloration pattern differs among species and is often used as diagnosis for new species (e.g., Conle et al. 2011).

The Anisomorphini genus Urucumania Zompro, 2004 currently comprises two described species presenting small scale-like wings and a robust body with relatively stout legs, occurring in Brazil, Bolivia and Paraguay. The type species Urucumania urucumana (Giglio-Tos, 1910) was described from females from the Urucum massif in the Pantanal in central Brazil, from where it takes the specific name and later the generic name as given by Zompro (2004). Urucumania borellii (Giglio-Tos, 1897), described from males and females from Paraguay, was also included by Zompro (2004) when stablishing the genus. Prior to the transfer of U. borellii to its current genus, Anisomorpha lurida Redtenbacher, 1906, also from Paraguay, was synonymized under the former by Conle and Hennemann (2002), an act accepted by Zompro (2004).

Two Brazilian species currently placed in Pseudophasma present remarkable similarities with Urucumania, also presenting a robust body with relatively large legs, being the only ones in the genus to bear scale-like wings. These species, Pseudophasma dentata (Stål, 1875) and Pseudophasma nigrovittatum (Piza, 1939), the former known only from the female and the latter from the male, show a similar overall contrasting coloration of black and beige to orange but with slightly differing patterns. Additionally, we observed that specimens from other localities also show slightly differing patterns with similar general colors. We conducted a careful analysis of the external morphology of both sexes, eggs and male genitalia on several specimens in order to resolve whether P. dentata and P. nigrovittatum should be transferred to Urucumania, and if they truly represent distinct species or are conspecific and together with specimens from other localities represent a single species with polymorphism of color pattern.

Therefore, in the present work we propose the new combinations Urucumania dentata comb. n. and Urucumania nigrovittata comb. n., redescribing both species based on type and new material collected near the type localities, and pointing out morphological differences between the two species. We also describe the male of U. dentata comb. n., the female and egg of U. nigrovittata comb. n., and 13 new species of Urucumania: Urucumania pirulai sp. n. (from Parauapebas, Pará, Brazil), Urucumania varellai sp. n. (from Abel Figueiredo, Pará, Brazil), Urucumania guadanuccii sp. n. (from Diamantina, Minas Gerais, Brazil), Urucumania atilai sp. n. (from São Miguel Arcanjo and Iperó, São Paulo, Brazil), Urucumania intervalica sp. n. (from Ribeirão Grande and Tapiraí, São Paulo, Brazil), Urucumania brasil sp. n. (from Loreto, Maranhão, Brazil), Urucumania tapirape sp. n. (from Barra do Tapirapé, Mato Grosso, Brazil), Urucumania rasocatarinensis sp. n. (from Jeremoabo, Bahia, Brazil), Urucumania dilatata sp. n. (from Umburanas and Sento Sé, Bahia, Brazil), Urucumania sertaneja sp. n. (from Piranhas, Alagoas, and Natal, Rio Grande do Norte, Brazil), Urucumania albopunctata sp. n. (from Santa Cruz, Buena Vista, Bolivia), Urucumania oriomadeirensis sp. n. (from Itaituba and Xinguara, Pará, and Itacoatiara, Amazonas, Brazil) and Urucumania candanga sp. n. (from Brasília, Distrito Federal, Brazil).

Material and Methods

The analyzed specimens are housed at the Museu de Zoologia da Universidade de São Paulo, São Paulo, Brazil (MZUSP) except for the holotype of U. nigrovittata comb. n., housed at Museu de Entomologia Luiz de Queiroz, Piracicaba, Brazil (MELQ), the type material of U. dentata comb. n., housed at Naturhistorisches Museum Wien, Vienna, Austria (NMW), type material of Urucumania albopunctata sp. n., housed at the collection of the Georg August University of Göttingen, Göttingen, Germany (Göttingen), type material of Urucumania candanga sp. n., housed at the collection of the Universidade de Brasília, Brasília, Brazil (UNB) and non-type material of Urucumania sertaneja sp. n., housed at Museum Paraense Emílio Goeldi, Belém, Brazil (MPEG). Supplementary information deduced from specimen labels is given in brackets. Depository institution for each specimen is given in parenthesis.

Biological observations were based on live specimens collected by active searches at night. Dry-preserved eggs were examined when possible, except for the eggs of U. dentata, extracted from within a female abdomen. Specimens and eggs were examined at Universidade Estadual Paulista “Júlio de Mesquita Filho”, Rio Claro campus (UNESP), and at MZUSP under Leica M125 and Leica M205 C stereomicroscopes and measured with a Mitutoyo digital caliper. Photographs of live specimens and the habitus were taken with a Canon EOS Rebel T5 camera equipped with a Canon EF-S 18–55 mm lens; a Canon EOS Rebel SL1 camera equipped with a Canon EF 100 mm F/2.8 Macro USM lens; or with a Canon EOS 70D camera equipped with a Canon 100 mm Macro lens. Pinned, dry preserved specimens were photographed with a Canon EOS Rebel SL1 camera equipped with a Canon EF 100 mm F/2.8 Macro USM lens and a Nikon D5000 camera equipped with a Nikon DX AF-S Nikkor 18-140 mm 1:3 5-56G ED lens. Specimens and structures were photographed under a Leica M205 C stereomicroscope with LAS Core software or with a Zeiss MRc5 camera coupled to a Zeiss SteREO DiscoveryV12 stereomicroscope and focus-stacked in the software Helicon Focus version 6.3.7 Pro. Illustrations were made using Adobe Photoshop CS6. The distribution map was prepared in QGIS 3.28.

Redescriptions are based on type specimens and the additional material cited for each species. Color descriptions are based on live specimens when possible, but the colors change in most dried specimens, especially due to fading. Measurements are given in millimeters, and the body is measured from the apex of the head to the posteriormost portion of the abdomen. In the text, the median segment can be referred to as “tergum I” when descriptions concern more parts of the abdomen. General terminology of the body follows Ghirotto (2021), that of the egg capsule follows Clark Sellick (1997), that of the terminalia follows Bradler (2009), and that of the internal male genitalia follows Chiquetto-Machado and Cancello (2021) and Ghirotto (2021).

Characteristics. The male genitalia of Urucumania species consist of a dorsal, a ventral and an internal sclerite, and a ventral and a dorsal lobe (Fig. 1). The dorsal sclerite is nominally divided into basal part and apical part, the latter bearing a main and a distal process (Fig. 1a). The ventral sclerite covers the tip of the ventral lobe and has a small narrow bump anteriorly. The internal sclerite is somewhat crown-shaped and is also nominally divided, into a main process bearing four projections, the two centralmost projections and the outer two flank projections, and an accessory process bearing an inner branch and an outer branch which usually bears a distal and a proximal part (Fig. 1f). The dorsal lobe is short and originates atop the dorsal sclerite.

External characteristics of Urucumania are illustrated in reference to the morphology of the type species of the genus, Urucumania urucumana, in Fig. 2, from males and females collected very near the type locality (Urucum massif in Corumbá and Ladário, Mato Grosso do Sul, Brazil, in the same mountain, the Urucum massif, where type specimens are from). Both sexes possess small, scale-like wings. The male has an emarginated posterior margin of the tergum X with small thorn pads pointing inward, near median line, with small teeth, and has a very large, bulgy poculum with large anterior portion further bearing an elongated dextral process originating superiorly from the anterior portion of sternum IX. The cerci of the female are short and cylindrical, and those of the male are longer, usually gently incurved.

Biology. Most Urucumania specimens observed alive are very active, moving a lot upon disturbances such as vibrations or handling. During the day, it is common for them to hide under logs, large leaves or stones, near the ground. They are able to spray a minty, slightly irritating substance from their prothoracic glands, if grabbed or poked. In captivity, specimens fed on Lantana (Verbernaceae), Ligustrum (Oleaceae), Rosa (Rosaceae), Hibiscus (Malvaceae) and Oldenlandia (Rubiaceae). Urucumania rasocatarinensis sp. n. were observed to feed on an undetermined Spermacoceae (Rubiaceae) plant in situ (Fig. 46).

Identification key. We provide an identification key for Urucumania based on adult males and females. We refrain from using eggs in the key due to its higher variation, generalized morphology between similar species and the lack of knowledge of the egg of several species.

Gomes and J. Conrado.

Differential diagnosis. Differs from other Urucumania by the larger head in dorsal and lateral views (Fig. 5a, c, i, l), the wider than long median segment, the dark orange coloration and wider aspect (extending to the lateral margin) of the dorsal paramedian bands on the body, the color pattern on the legs with femora black with dark orange in basal portion and dark orange tibiae and tarsi (Fig. 4), and the aspect of the male genitalia (Fig. 6), with a short sclerite of the ventral lobe with straight posterior margin, tapering towards the left side and a dorsal sclerite with thin left process with a widened round apex and right process forming three round margins.

Distribution (Fig. 68). Only known from Santa Catarina Island, Santa Catarina, Brazil, in the Atlantic Forest.

Remarks

Redtenbacher (1906) provided a description of male for P. dentata, but we do not consider this description as valid for the species due to the overall similarity between different species of Urucumania, several of which could match with the description provided, added to the vague locality relatively distant from type locality.

Differential diagnosis. Differs from remaining Urucumania by the lighter orange bands and the not too narrow nor too thick dorsal paramedian bands not reaching the lateral margins of the body, the color pattern on the legs with femora gradually turning from dark orange or red in basal portion to black at apex, tibiae apically with a light orange stain contrasting with black gradually turning dark orange or red towards apex, and orange to red tarsi (Fig. 10), and the aspect of the male genitalia (Fig. 12). From Urucumania dentata comb. n., it differs by the less robust body (Fig. 10), relatively smaller head (Fig. 11a, i), the longer, thinner and more curved cerci of the male (Fig. 11d, e, g, h), and shorter cerci of the female (Fig. 11j, l, n).

Etymology. The species is named after Dr. Paulo Miranda Nascimento, nicknamed and mostly known as Pirula or Pirulla, a Brazilian paleontologist and science communicator. Acting mostly via YouTube videos in his channel ''Canal do Pirulla'', Pirula is regarded by us as one of the most important science communicators of Brazil, especially, but not only, in the area of biological sciences, with proficient treatment of scientific and other matters. Pirula was a strong reference as a scientist for VMG in his early career. This homage also makes sense because despite YouTube system favoring only short videos to be more discoverable, Pirula achieved popularity even with his long videos, unusual among youtubers, coinciding with phasmids being unusually long insects. After the dark times that recently shadowed science in Brazil, popularizing the importance of science is vital.

Differential diagnosis. Differs from remaining Urucumania by the dark-orange color pattern with bright yellow wings and black legs with basal and apical area of femora and basal area of tibiae yellowish (Fig. 15), and the shortened tergum X in both sexes (Fig. 16d, j), and the basally widened right process of sternum IX of males (Fig. 16g). The overall coloration pattern resembles U. varellai sp. n., but the female of U. pirulai sp. n. can be distinguished by the other mentioned characteristics.

Etymology. This Amazonian species is named after Drauzio Varella, a Brazilian oncologist, infectious disease specialist, scientist, educator and best-selling author. Varella was a pioneer in the treatment of AIDS in Brazil and since the 1980s has had an important role in educational campaigns about this syndrome. During the past three decades he has also led a prospective research program on the medicinal potential of Brazilian Amazon plants and has been an active and successful science communicator in the radio, television and Internet.

Differential diagnosis. Females (the only known sex) differ from remaining Urucumania by the dark-orange color pattern with bright yellow wings, beige tibiae and tarsi, femora black with beige at the extremities (Fig. 19), the widened and round head (Fig. 20a), the slightly wider than long tergum X (Fig. 20d, e), and relatively short (around 3 × longer than wide) cerci (Fig. 20f). The overall coloration pattern resembles U. pirulai sp. n., but the female of U. varellai sp. n. can be distinguished by the other mentioned characteristics.

Holotype, 1f#: Brazil, Minas Gerais, Diamantina, campus of Universidade Federal dos Vales do Jequitinhonha e Mucuri—UFVJM, 18°11′39.6"S 43°34′18.5"W. Cerrado de campos rupestres. 25.x.2018. V. M. Ghirotto, R.F. Ferreira and A. Galleti-Lima col. (MZUSP 2592).

Paratypes, 3 m# (MZUSP 2591, 1744, 1745), 5f# (MZUSP 1746–1750), 25 eggs: Brazil, Minas Gerais, Diamantina. Reared in captivity by V. M. Ghirotto from female 2592 [holotype], died 2.iv–1.vii.2019.

Etymology. The species is named after Dr. José Paulo Leite Guadanucci, an expert Brazilian arachnologist and skillful researcher. He was a professor and researcher in UFVJM at Diamantina, the type locality of the new species, before moving to Universidade Estadual ''Júlio de Mesquita Filho'' (UNESP). He advised VMG in his undergraduate course in biology at UNESP, working with mygalomorph spiders. Besides, he supported VMG in his first practices regarding stick insects that eventually led to the foundation of Projeto Phasma—a freestanding phasmid research group of which some of the authors, VMG, PWE, PABAN, EBC and PICM, are part of. The early start in researching phasmids by us and early foundation of the Projeto Phasma were made possible by Dr. Guadanucci's assistance. This comes in the form of our sincerely gratefulness for kindly helping us and supporting research on Phasmatodea in Brazil.

Differential diagnosis. Differs from remaining Urucumania by the dark-orange color pattern with dark legs (Fig. 21), the elongate terga VIII–X in both sexes (Fig. 22e, j), the widened dextral process of sternum IX of males (Fig. 22h), and elongated cerci of the female (Fig. 22j). Females further differ from Urucumania tapirape sp. n., another species with elongated terga VIII–X, by the shorter head (Fig. 22a, i) and terga VIII–X (Fig. 22e, j) and distinct color pattern (Fig. 21).

Distribution (Fig. 68). Only known from Diamantina, Minas Gerais, Brazil, in areas of campos rupestres, a rocky savannic Cerrado in the Espinhaço formation.

Etymology. The species is named after Dr. Atila Iamarino, a Brazilian microbiologist best known for his significant science communication contribution spanning several fields of knowledge, mostly through the YouTube channels “Nerdologia” and “Atila Iamarino”. He was also a guiding voice to Brazil amidst the recent COVID-19 pandemic, broadcasting trustful, scientific and public health information.

Differential diagnosis. Differs from remaining Urucumania by the lighter, reddish to beigeish-orange coloration and the narrow width aspect of the dorsal paramedian bands on the body (not reaching the lateral margins), by the color pattern on the legs with dark tibiae and femora but femora basally reddish to orangish (Fig. 27), and by the aspect of the male genitalia (Fig. 29). Both sexes are also distinguished by the body and head proportion (Fig. 28a, i), males can be further distinguished by the short, thickened cerci (Fig. 28d, e), and females by the medium sized cerci (Fig. 28j, m, o).

Distribution (Fig. 68). Only known from Iperó and São Miguel Arcanjo, São Paulo, Brazil, in areas of inland Atlantic Forest.

Etymology. The specific epithet is a noun in apposition derived from a Portuguese adjective, in reference to the general color of the species as it might resemble a burning piece of carbonized wood, as ember, “brasa” in portuguese and “brasil” when meaning ‘like ember’. Specimens seen but not collected showed an orangish coloration much resembling ember. The epithet is also a reference to Brazil, especially as the country also takes its name, although indirectly, from ember, due to the coloration of the wood of a Brazilian tree species, the pau-brasil.

Differential diagnosis. Females (the only known sex) differ from remaining Urucumania by the striking black and yellow coloration pattern with legs black with femora basally reddish (Fig. 37), proportions of the head (1.2 × longer than wide; Fig. 38a) and terga VIII–X (tergum X as long as wide; Fig. 38d), the very wide epiproct (Fig. 38d), and the thick, slightly conical cerci about 2.7 × longer than wide (Fig. 38d-f).

Distribution (Fig. 68). Only known from Loreto, Maranhão, Brazil, in a savannic area of the Cerrado.

Remarks. Although bearing contrasting patches of black and yellow resembling some aposematic animals, in fact the coloration pattern of the species likely helps it camouflaging amidst clear, pale and darker dry leaves in the soil of its habitat, as seen for the live specimen.

Materials examined

Holotype, 1f#: Barra do Tapirapé [Santa Teresinha, Tapirapé], Mato Grosso, xii.1962, B. Malkin col. (MZUSP 0203).

Etymology. The specific epithet is a noun in apposition referring both to the type locality, the mouth of the Tapirapé river, as well as the Tapirapé indigenous people inhabitants of that area. The Tapirapé people were driven out of their original territory from centuries ago by urban and farming expansion and were divided in more than one area, some inhabiting the Tapirapé area in Mato Grosso for centuries until today. Their craft often display patterns of beige and black similar to those of the new species.

Differential diagnosis. Females (the only known sex) differ from remaining female Urucumania by the beige color pattern with orangish tibiae and tarsi and femora black with orangish base (Fig. 39), and by the elongate head (Fig. 40a) and terga VIII–X (Fig. 40d, e).

Distribution (Fig. 68). Only known from Santa Teresinha, Mato Grosso, Brazil, in a savannic area of the Cerrado.

Remarks. The locality is given as “Barra do Tapirapé” which means “Tapirapé’s [river] mouth bar’’, so the locality most probably refers to the mouth of the Tapirapé flowing into the Araguaia river, in Santa Teresinha municipality—Mato Grosso state.

Etymology. The specific epithet is an adjective derived from the type locality, Raso da Catarina, a plateau in the Caatinga biome. The Raso da Catarina region appears to be a very important area for the Caatinga bearing endemic species such as the endangered Lear's indigo macaw.

Differential diagnosis. Differs from remaining Urucumania by the dark orange and brown color pattern with brown legs, and by the very robust body (Figs. 41, 42). The robust body resembles Urucumania dilatata sp. n. and Urucumania sertaneja sp. n., from which it differs by the orange banded color pattern, less developed posterior projections of terga and the smaller wings (Figs. 41, 42).

Distribution (Fig. 68). Only known from Jeremoabo, Bahia, Brazil, in the Raso da Catarina plateau in the xeric Caatinga.

Etymology. The specific epithet is an adjective from the Latin word "dilatatus" meaning thick, enlarged, referring to the very widened body, especially the thorax, characteristic of the new species.

Differential diagnosis. Differs from remaining Urucumania by the very dark color pattern with bright yellow wings and dark legs, and by the very robust body with laterally projecting terga (Figs. 47, 48). The very robust body resembles Urucumania rasocatarinensis sp. n. and Urucumania sertaneja sp. n. from which it differs by the relatively more widened thorax and larger wings (Figs. 47, 48).

Additional material examined, 2f#: Brazil, Rio Grande do Norte, Natal, Sanvalle, Parque da Cidade. 23.x.2009. M. L. S. Lopes col. (MPEG).

Etymology. The specific epithet is an adjective from Portuguese meaning inhabitant of the “sertão”, a Brazilian semi-arid region bearing the Caatinga biome. The new species was found very near the São Francisco river, which has a high significance for the “sertão” being the most important water source in that dry area.

Differential diagnosis. Differs from other Urucumania by the very darker color pattern with faint dark orange to reddish dorsal stripes, and by the very robust body with laterally projecting terga (Figs. 53, 54). The very robust body resembles Urucumania dilatata sp. n., from which it differs by the smaller alae and less widened thorax (Figs. 5354) and Urucumania rasocatarinensis sp. n., from which it differs by the distinct color, the slightly larger allae, the larger thoracic spines, shorter tergum X of the female and more robust thorax and abdomen of the male (Figs. 53, 54, 55).

Distribution (Fig. 68). The type material is known from Piranhas, Alagoas, Brazil, in very dry areas of the xeric Caatinga. The females from Rio Grande do Norte could be revealed to represent a distinct species (see Remarks below).

Remarks. Two females from Natal, Rio Grande do Norte state (Figs. 56, 57) only differ from female type specimens from Piranhas by their very short cerci (Fig. 57b, d, g). Males from that population would be helpful to confirm its identity.

Etymology. The specific epithet is an adjective derived from the Latin words “albus” meaning white and “punctatus” meaning punctuated, referring to the lateral white dots present on the new species.

Differential diagnosis. Males (the only known sex) differs from remaining males of Urucumania by the dark color pattern with white medial line and white lateral dots at the abdomen (Fig. 58), absence of wings (Fig. 59b), and presence of two lateral processes, on each side, of sternum IX (Fig. 59h, i). A female photographed alive but not collected also seems to bear a light-colored medial line and lateral dots and also be totally wingless (Fig. 61b).

Distribution (Fig. 68). Only known from Buena Vista, Santa Cruz, Bolivia, in areas of humid and mountainous forests with Amazonian influences.

Remarks. Although we lack a female voucher to describe, a living mating pair (Fig. 61b) of Urucumania albopuncatata sp. n. was photographed by Ramon and Suzanne Vargas, found by their son Rio Vargas, in Buena Vista, Santa Cruz, Bolivia, around 25 km from the holotype and paratype localities. The female has the same overall color pattern as the male, including the white dots laterally on the abdomen, as well as some characteristics that are shared by both sexes in other species of the genus, such as the small curved projection at the posterior margin of terga and the prominent granules on thorax (Fig. 61b). Furthermore, the female appears to be totally wingless like the male.

Etymology. The specific epithet is an adjective and refers to the known distribution of the new species in the Amazon, occurring east of the Madeira river and south of the Amazon river. The biogeography of the Amazon is often divided into areas roughly corresponding to interfluves, mainly delimited by the Amazonas, Madeira and Negro rivers as already recognized by earlier biogeographers (Wallace 1854). The new species is unable to fly and thus could be more liable to be isolated by large rivers.

Differential diagnosis. Differs from remaining Urucumania by the dorsally orange, laterally black and posteriorly darker color pattern (Fig. 62), the fine granulation on the body surface (Fig. 63), the third antennomere more elongate, as long as pedicel and scapus in females and longer than pedicel and scapus in male, the slightly elongated alae (Fig. 63b, o), the terga I–II without elliptical dorsal projections (Fig. 62b, e), the female conical cerci (Fig. 63p), and the basally widened right process of sternum IX of males (Fig. 63h).

Distribution (Fig. 68). Only known from Itaituba and Xinguara, Pará and Itacoatiara, Amazonas, Brazil, in the Amazon.

Etymology. The specific epithet is an adjective from Portuguese meaning inhabitant of Brasília, the type locality.

Differential diagnosis. Differs from remaining Urucumania by the dark-orange color pattern with dark legs (Figs. 64, 65), the elongate terga VIII–X in both sexes (Fig. 66d, g, j, m), the widened dextral process of sternum IX of males (Fig. 66h), and elongated cerci of the female (Fig. 66j). Females further differ from Urucumania tapirape sp. n., another species with elongated terga VIII–X, by the shorter head (Fig. 66a, f, i) and terga VIII–X (Fig. 66j, m) and distinct color pattern (Fig. 64).

Distribution (Fig. 68). Only known from Brasília, Distrito Federal, Brazil, in savannic areas of the Cerrado.

Discussion

With the 13 new species described here and the additional two species transferred from Pseudophasma, Urucumania now contains 17 species, representing an increase of 850% in the number of species. The high diversity revealed in this research highlights the potential for discovering new species of stick insects, especially in poorly sampled areas, as well as the need of revision for several groups of stick-insects. Urucumania is a more diverse genus than previously thought, now known to be broadly distributed in Brazil, occurring in dry to humid, open to forested habitats. Moreover, nine out of the 13 new species derive from recently collected material, mostly from active efforts of Projeto Phasma to sample phasmids specifically, also counting on the help of third parties. This shows that even few resources dedicated to sampling can result in the discovery of high amounts of new phasmid species, greatly contributing to reducing the taxonomic impediment (Engel et al. 2021). Preliminary observation by the authors further suggest many more undescribed species of Urucumania which would be discovered with increased sampling effort; for example, note the wide gaps in the known records for Urucumania in Fig. 68. Some unsampled populations from the South of Brazil show much similarity to one another, as seen for example in pictures taken by citizens of unsampled material. Studies focusing on similar Urucumania representatives would be a welcoming effort on future studies on the genus, especially if including in other analyses such as the use of molecular work. The genus Pseudophasma still includes several heterogeneous species and is in need of revision (see also Chiquetto-Machado 2018 and Robertson et al. 2018), with the expectation that more of its species will be transferred to other genera.
