(Odhner, 1925)
Small species, the carapace is relatively narrower and each lobule extremely convex and clearly demarcated by deep grooves; 2M is completely divided into two lobules, the inner one of which is narrower; the anterior half of 3M is extremely narrow. The antero-lateral borders bear four markedly convex lobules, the anterior one of which is nearly fused with the external orbital angle. The wrist bears about five or six lobules, the palm about five. The carpus and propodus of ambulatory legs are also divided into about three lobules. (T. Sakai, 1939: 490)
