Diagnosis Ocular tubercle a truncate cone with apical papilla. Abdomen carried almost horizontally, extending to distal rim of first coxae of fourth leg pair, with several dorsodistal setae. Proboscis proximally broad, globular, with distal 0.6 narrowly tapered to down curved, narrow tip. Chelifores 1 segmented knobs hardly showing in dorsal view, only as long as their width. Palps of 5 or sometimes 6 segments, with proximal constriction marking segmentation for sixth segment when present, armed with few lateral and dorsal setae and field of short ventral setae on terminal segment; third segment longest. Oviger seventh segment with large apophysis bearing 5 or 6 slender spines; seventh to tenth segments carried anaxially, recurved; terminal segment with 2 large spines, one denticulate. Legs short, robust, with typical setose dorsal swellings. Propodus well curved, with many dorsal setae, 3 large heel spines, and few sole spines. Auxiliary claws about 0.6 main claw length (Ref. 2115, p. 35-37).
