Abstract
In recent decades, the strepsirhine family, Lorisidae1, has been thought of as consisting taxonomically of only four extant genera, of which two are considered to be monotypic: the Asian Loris (which is now apparently confined to the island of Sri Lanka), and the African Perodicticus potto. The African genus, Arctocebus, apparently comprises two species, A. calabarensis and A. aureus. And the Asian genus Nycticebus also is supposed to embrace only two species, N. pygmaeus and the somewhat larger N. coucang. N. pygmaeus is distributed roughly throughout the mainland of southeast Asia. N. coucangis sympatric with N. pygmaeus on the mainland, but also occurs on the islands of Borneo, Sumatra, Java, and, purportedly, the Philippines.
