A, B; 11C, D). Surface whitish, with small pits all over, 1.3 times as long as wide. With two oblique carinae enclosing a large antero-dorsal area (plateau). At about 1/3 of its length from the front, each oblique carina joins another carina that runs down vertically to turn forward abruptly at 45 degrees. This angulated carina borders an anterior trapezoidal area on each side of carapace and bears a strong horn before ending on inferior margin of carapace. Posterior part of carapace with three horizontal (inferior, middle and upper) carinae. The inferior carina, the strongest, starts on the apex of the angulated carina and ends at hinter margin of carapace; the middle and upper carinae run backwards from oblique carina, the middle one disappears a short distance before reaching hinter margin of carapace, the upper one extends to hinter margin. Ocular lobe wider than long, without lenses. Pseudorostrum approximately 4 times as long as ocular lobe. Inferior margin of carapace finely serrate. Antero-lateral angle absent, antennal notch shallow.

This uropod endopod with a minute distal article is unique for the genus. There may exist the possibility that in the endopod drawn by Bäcescu and Petrescu (1991) the second article is cracked distally (or the distal spine broken basally) and thus, the endopod has actually two articles. Unfortunately, the uropod depicted by Bäcescu and Petrescu (1991) in their fig. 4E was lost after dissection, and the endopod still present on the

It has no rudimentary exopods on the third and fourth pereopods in the female, the maxilliped 3 is not markedly expanded distally, the uropod endopod bears three articles and is shorter than the exopod, and it possesses a large telson (extending as far as the end of the uropod peduncles). It should be noted that many species at present included in this speciose genus do not fit one or more of the features listed above.
