Diagnosis

Antennule seven-segmented and antenna eight-segmented. Antennula slightly longer than antenna. Mandibular palp three-segmented, with three strong claws. Maxillula with very long and thin seta-like claws in both endites, and outer margin of distal endite with only two subterminal setae. Maxilla three-segmented. Endopod of ThI-VII four-segmented; exopod of ThI inserted in the middle part of the basipod, not distally as in other thoracopods. Male ThVIII highly elongated; penial region with three very well-developed lobes/protuberances, trapezoidal inner lobe; elongated outer lobe, similar in length to inner lobe; outer protuberance as long as basipod, with distal teeth; basipod large, integrated in penial region, vertical, with frontal crest provided with distal tooth and one distal seta; exopod highly elongated, as long as the exopod of other thoracopods, but thicker, with three setae; endopod two-segmented, as long as exopod, and ornamented with one spine and one seta. Uropod: sympod with six spines, with the two distal ones slightly longer than others; endopod with many spines, the distal ones very long, and long setae; exopod similar in length to endopod, with several setae of different size, the two distal longest. Small, almost square furcal rami with denticles on outer distal end (possibly representing the furcal organ) and three spines: two of different size and a small dorsal one.
