, the caudal ramus is 1.5 times longer than wide, two distal setae on the mandibular palp are extremely unequal in length (longer seta six times longer than shorter one), and the genital double-somite of the female is ornamented with about 25 spinules arranged along the entire postgenital lateral margin. Most of all, the nature of the sexually dimorphic morphological transformation of the endopod of male leg 1 is unique to the new species.
