Genus Hepomadus Bate, 1881

Integument glabrous. Rostral length in juvenile females and apparently, in all males, not exceeding 0.7 times that of carapace, in larger females length increasing to as much as 1.25 carapace length, reaching beyond distal end of antennular peduncle by half its length, bearing 2 dorsal teeth near base, followed by single postrostral tooth. Carapace with postrostral carina almost reaching posterior margin; hepatic spine present; orbital, and postantennal spines absent; cervical sulcus well marked, reaching middorsal line; postcervical sulcus faint; branchiostegal carina anteriorly sharp, posteriorly weak; hepatic sulcus distinct; hepatic sulcus distinct; branchiocardiac carina strong, accompanying sulcus deep. Eye with cornea well developed; calathus with proximal tubercle on mesial margin. Dorsal antennular flagellum short, flattened for most of its length; ventral flagellum elongate, slender terete, not modified in mature male. Scaphocerite blade distally rounded, rigid lateral margin with tooth at distal 5/6 of length.

First to fifth pereopods each with exopod reduced or absent; merus of first and second pereopods with cuspidate setae; fourth and fifth pereopods slender. Thelycum open, with large roughly lanceolate median protuberance on sternite XII; sternite XIII subrectangular, weakly convex.

Petasma with median lobule distally flexed ventraly; lateral lobule reaching or barely surpassing median lobule; about distal half of ventral costa free from adjacent flexible part of lateral lobule, its tip curving laterally, forming a hook. First and second abdominal somites dorsally rounded; third to sixth somites dorsally carinate, third somite carinate in posterior two-thirds, ending posteriorly in spine. Telson with 4 pairs of lateral movable spines; apex slender acute (modified from Pérez Farfante & Kensley, 1997).
