A). Second antennae proximal segment subcylindrical, distal segment slender, directed posteriomedially. Antennal appendage long, peduncle stout, “S” curved, longer than second antennal proximal segment, with four anteriolateral subcrenulate papillae proximal to the first curve. Peduncle bears a lateral row of slender spines at the distal curve. Cheliform “hand” elongate; “thumb” shorter than peduncle, bearing an arcuate spur, and an anterior “shoulder” opposite the spur. “Finger” is as long as peduncle, bifid, with posterior ramus smooth and arcing anteriorly, anterior ramus spinose on anterior margin, bending apically in the distal third. Anterior ramus of finger with spines arranged as a series of long spines with shorter spines interspersed in between. Longitudinal row of spines from the distal end of the anterior ramus of the finger turns to the medial surface of the ramus and at the end on the posterior surface it split into two (bifid structure) (
