. The right cheliped of the sole female known at that time is noted to be subequal in length to, and only slightly stouter than, the left cheliped. Komai (2006) considered that the right cheliped was probably in the process of regeneration because the right cheliped is larger than the left cheliped in the other known species of

, however, the chelipeds of the three females are all subequal in size. Therefore, the subequal chelipeds seem to be normal for this species. Two small male specimens (sl 1.0, 1.0 mm; CBM-ZC 9215) also have chelipeds being subequal in length, but the right cheliped is slightly or distinctly stouter than the left cheliped.
