Diagnosis Trunk robust, compact, with 2 tall median tubercles about as long as abdomen, each with lateral and posterior spines. Ocular tubercle more than half as long as trunk tubercles. Lateral processes moderately long, separated by less than their diameters, with low dorsodistal and laterodistal spinose tubercles. Abdomen long, distally downcurved, with short proximal, median, and distal spinose tubercles. Proboscis very inflated. Chelifore scapes 2 segmented; first segment very short, second almost 4 times longer, with short median and distal spinose tubercles; chelae bulbous, vestigial. Oviger fifth segment almost as long as fourth; terminal segment tiny, with 2 setae. Legs with many dorsal and lateral spinose tubercles only slightly longer than segment diameters; propodus well curved, with marked heel bearing 3 spines (Ref. 2115, p. 31).
