(Shen, 1935)
Small species, the entire animal hairy. The carapace is distinctly broader than long, the dorsal surface uneven and the gastric and cardiac regions well demarcated. Front deeply concave in the middle portion, the postfrontal ridge bilobate, i.e., the usual ridge on either supraorbital border is not defined. The external orbital angle and the second antero-lateral tooth are deeply cut, while the third tooth is entirely rudimentary. Of the oblique ridges on the posterior lateral surfaces, the anteriormost one (which extends from the third imaginary antero-lateral tooth) is most prominent and beaded with microscopic granules. The wrist and palm are covered with very soft hairs; on denudation, the outer surface of palm is traversed by three indistinct longitudinal ridges, which are furnished with fine granules. Fingers are not gaping, the merus of ambulatory legs are extremely broad and its posterior distal portion is expanded and terminates in two or three spinules. Carpus and propodus are slender, their anterior borders thickly covered with soft hairs. The terminal segment of male abdomen is extremely elongate and rounded at tip. (T. Sakai, 1939: 687)
