Carapace 1.30 times as long as wide. Middorsal carina sharp, extending nearly to posterodorsal margin of carapace, armed with two large teeth; epigastric tooth falling far short of base of rostrum arising at 0.22 of carapace length; second tooth equal in size to the first, arising from 0.57 of carapace length. Dorsal surface of carapace without setae. Antennal tooth small, not reaching anterior margin of cornea of eye. Branchiostegal tooth directed forward, falling short of anterior margin of antennal basicerite. Pterygostomian angle without tooth. Lateral face of carapace with relatively large hepatic and one post hepatic tooth, but epibranchial tooth absent; epibranchial carina conspicuous. Sternal tooth on fifth thoracic somite well developed in male, extending beyond base of spur on fourth somite. Second abdominal somite smooth on dorsal surface. Third somite with middorsal carina in posterior 0.52; posterodorsal margin of somite strongly produced posteriorly, partially covering fourth somite. Sixth somite about 1.80 times as long as high; dorsal surface flat on midline. Telson with two pairs of minute dorsolateral ... |
