; the number of spines on the dorsal margin of chelae varied from 2 to 6 spines on the propodus and 3 to 5 on the dactylus. The large outward curving spine and a small accessory spine on ventral margin of the merus of the third walking leg was absent in the left leg of one female, and in the damaged male was replaced by a bifid large spine. In addition, the condition of the accessory spine near the spur varied in some specimens—it was absent in one female, and there were three small spines (instead of one) in the right leg of one male; also, it was located at the base of the spur in most of the specimens but it was located laterally in two females.
