New species and records of Exalloniscus Stebbing, 1911 from southern Asia (Malacostraca, Isopoda, Oniscidea)

Abstract

The genus Exalloniscus is widely distributed in southern and eastern Asia. In this contribution, eight species are described as new: Exalloniscus schmalfussi from Nepal; E. siamensis from Thailand; E. kampucheaensis from Cambodia; E. tortilis and E. deharvengi from Vietnam; E. stilifer from southern China; E. burmaensis from Myanmar; and E. convexus from Laos. Ten more species are recorded: E. nepalensis from Nepal; E. coecus, E. brincki, E. bicoloratus, E. caudatus and E. maschwitzi from West Malaysia; E. sumatranus from Sumatra, Indonesia, and Singapore; E. papillosus from West Malaysia and Vietnam; and E. thailandensis from Laos. Exalloniscus bessoni Dalens, 1992 and E. yinae Nunomura and Xie, 2000 are considered to be junior synonyms of E. thailandensis Dalens, 1987. A map with the recorded distributions of all the 28 species of Exalloniscus is provided and their habitat is discussed.
