(de Man, 1887)

The regions of carapace elegantly defined by rather deep grooves, especially, 3M, 2L, 3L, 4L, 1R are respectively well demarcated. Front nearly one third as broad as the greatest width of carapace, the free margins are slightly arcuate and the median notch shallow, they are separated from the supraorbital border by a broad shallow sinus. Of the four antero-lateral teeth, the first is very low and completely fused with the orbital angle, the second is also very low, while the third and fourth are somewhat obtusely angular. The basal antennal segment is very slightly longer than broad, having no lobule at its tip.
Chelipeds are subequal, the wrist has two obtuse teeth at the inner angle and its upper and outer surfaces are covered with 7 to 8 nodules, which are circumferenced by smooth grooves; palm has two indistinct grooves on outer surface. Ambulatory legs are very slender and naked excepting the setae of the dactylus.
This species was originally referred to genus Panopeus by de Man, but on account of the different character of carapace, chelipeds, and basal segment of antenna, I followed Rathbun with regard to the generic name, although not to the specific name. (T. Sakai, 1939: 468)
