Propodus of cheliped small, upper edge convex, densely granulate, lower margin straight from near the wrist to end of finger; outer surface with a granulate ridge just above lower edge, continued to end of finger and fringed above with hair, also a line of granules through the middle, and 2 lines of punctae and hairs on upper half.
