Abstract
    This paper contains a study of the genus Psopheticus based on collections from the area around Madagascar (leg. CROSNIER & CLEVA, BENTHEDI Exp.); from Réunion (Marion-Dufresne 1982, MD32); from the Philippines (MUSORSTOM 1-3) , from the Makassar Strait (CoRINDON 2, 1980); and from New Caledonia (BIOCAL and MUSORSTOM 4, 1985). The type species, P. stridulans Wood-Mason, 1892, is redescribed, based on a topotype, from the Andaman Sea. In addition the genus contains P. insignis Alcock, 1900 and P. hughi Rathbun, 1914, both of which are redescribed, and P. vocans Guinot, 1985. Three new species are erected: P. crosnieri from Madagascar; P. musicus from the Philippines; and P. insolitus from the Makassar Strait. Specimens previously reported as P. stridulans by GUINOT, from Réunion, have been reexamined and are considered of uncertain status but close to P. stridulans. A key is provided for identification of the species. The armature of the ambulatory legs was found to be a reliable and complex specific character, independant of sex and age, and is described for each species. A large series of P. insignis evidenced pronounced allometry in the growth pattern of the anterolateral edge of the carapace and a sexual dimorphism with longer chelipeds in the male.
