Diagnosis.—Carpus of ambulatory legs with a trilobed crest. Distal end of abdominal segments of male with a band of pubes- cence. Tubercula- tion of carapace fine, inconspicuous. Description.—Com- pared to M. spinim- anus, the carapace is shorter and broader, lobules similar in shape and position, their area of tuber- culation diminishing with age; front less advanced, its lobes less oblique. Cardiac and metagastric re- gion each divided by a median sulcus into two lobules. Chelipeds more feebly roughened than in spinimanus; teeth on upper border of hand very unequal, the second, counting from the wrist, largest, the distal one a low tubercle. Ambulatory legs shorter than in the allied species; merus denticulate or spinul- ous on upper margin, carpus with a trilobed crest above, propodus with a row of three smaller lobes or teeth on each side of the upper surface; a similar row on each side of the carpus of the first three legs, and on the outside of the last leg. Legs hairy, especially the. Figure 44.—Medaeus lobipes, male, holotype, carapace mm. wide, dorsal view.
