The number of the postrostral teeth on the carapace is variable, four in the male specimens or five in the female specimens, although it could not be concluded if this variation is sexrelated. Ventral teeth on pleura of the pleon seem to become smaller with increase of the animal size in females. The number of ventral teeth of the fifth pleomere is variable from two to four (mostly three) on one side, but none of the specimens examined has two ventral teeth on both sides.
