The species had been confused for many years with Osachila stimpsoni Studer, 1833 , and had been described as that species by Monod (1956) and by Guinot (1966 , 1967 ) (see remarks in Manning and Holthuis, 1981: 325 ). It is known from several localities along the coast of west Africa from depths of 65 to 132 m ( Guinot and Forest, 1966 ; Manning and Holthuis, 1981 ). The male holotype ( RMNH Crust. D. 31541) is housed in the Rijksmuseum van Natuurlijke Histoire, Leiden, The Netherlands ; the male paratype ( USNM 139766) is in the National Museum of Natural History, Smithsonian Institution, Washington, D.C. The first author examined the male paratype , which consists only of the carapace and abdomen (no appendages) and found that it agrees well with the original description and illustrations of the holotype given by Manning and Holthuis (1981) (figure repeated here as our Fig. 10 ). The paratype , which is exactly half the size of the holotype (CL 11.5 mm , CW 15 mm , vs. CL 22 mm and CW 30 mm for the holotype female), is noticeably more toothed on the lateral and posterolateral borders of the carapace.
