, which also has 2 hooks in retinacules on pleopods and different rami of uropod I, the new species can be clearly separated by the absence of specific spoon-shaped process on uropod I, significantly larger inner ramus of uropod III and the presence of only 1 ventral inner spine of dactyli of ambulatory pereopods. Moreover, males of the new species are well distinguished from the Caucasian congeners by the large endopod of uropod III, which is at least 1/3 of the length of the first segment of exopodite.
