) rather short (ratio rostrum length:carapace length 0.55), stout (basal height about one quarter its length), moderately upcurved, with strong lateral carina on each side, extending entire length of rostrum but no further on carapace; upper border armed with 5 small teeth, subequal in size except for distal tooth reduced as tubercle; first tooth situated barely beyond level of posterior margin of orbit, following two equally spaced teeth, whereas distance separating fourth from third teeth corresponds to 3/4 distance between two preceding teeth, distance between fifth and fourth also represents 3/4 distance between two preceding teeth (third and fourth); last 3/10 of rostrum upper border unarmed. Ventral border of rostrum armed with 9 teeth, size of teeth increasing from first to fourth, then decreasing; last tooth reduced to tubercles; tip of first tooth situated just beyond tip of stylocerite, distal tooth subapical.

Third segment with longitudinal dorsal carina, extending only along always visible part; two following segments carinated dorsally along their entire margin; these carinae rather rounded in transversal section, that of third segment being the bestmarked. Sixth segment devoid of carina, with regularly rounded transversal section. Pleura of first, second, third abdominal segments rounded, unarmed, that of fourth segment with posteroventral denticle, that of fifth with posteroventral angle ending as spiniform tooth. Sixth abdominal segment with well developed posteroventral spiniform tooth, its posterior lobule, which covers base of lateral side of telson, ending in a stout spiniform, ventrally recurved tooth.
