Abstract: The second species of the deepwater holothuriophilus pinnotherid genus, Alain Manning, 1998, A. raymondi sp. nov., is described from the Philippines. Alain was originally, but erroneously diagnosed as having a 6-segmented male abdomen. All species of Alain, however, have a 7-segmented abdomen in both sexes; the generic diagnosis is emended. An unusual feature of species of Alain is male androgyny, a phenomenon otherwise known among pinnotherids only from Nepin-notheres androgynous Manning, 1993b. We also take the opportunity to report the first case of male androgyny in Pinnotheres novaezelandiae Filhol, 1885, a New Zealand species that is herein transferred to Nepinnotheres. Among pinnotherids, androgynous males are now known from four species in two genera. Little is known of the biology of most pinnotherids, and androgyny may be significantly more prevalent than currently recognized. Copyright © 2008 Magnolia Press.
