Female with 4-articled antennule, third article longer than second; antenna 6-articled, articles 2 and 3 with slender distal spines, article 2 without ventral spine; maxilliped basis with four long setae extending to half length of second palp article, endites distally with single seta and three slender spatulate spines; cheliped relatively slender, merus covering less than half of ventral margin of carpus, propodus (palm of chela) nearly twice as long as wide; dactylus plus unguis on first pereopod 1.5 times as long as propodus; merus of pereopods 2 and 3 with ventrodistal spine about two-thirds as long as carpus; pleopod without inner plumose seta on the pleopod endopod; uropod exopod 1-segmented, endopod 5-segmented, with all segments elongate (more than four times as long as wide). Otherwise typical of the family. Male showing dimorphism in the antennule with secondary segmentation of the flagellum to more than 17 segments, proximal flagellum segment bearing large dorsodistal spine almost as long as flagellum; cheliped slender, sinuous; posterior pereopods without flange on basis. Sub-adult male with five-articled antennule.

; females of that genus are remarkably conservative in their morphology, a factor which in the past has lead to over-synonymization. The present species has a sufficient number of distinguishing characters, notably the slender chela (somewhat reminiscent of that of a typhlotanaid); the very slender distal spines on the second and third peduncle articles of the antenna; the proportionately very long dactylus and unguis of pereopod 1; the long ventrodistal spines on the merus of pereopods 2 and 3; the lack of an inner plumose seta on the pleopod endopod; and the elongate proximal uropod segments, that it warrants separation into a distinct genus.
