Fig. 18

Revised definition. Diamysini with cornea present as small external rudiments distally on the large eyestalks in both sexes (Fig. 18 B, C). Antennal scale without spines, setose almost all around (Fig. 18 A, D); scale with short apical segment, terminally rounded in both sexes. Carapace with a pair of post-suborbital spines, and without fringes in both sexes (Fig. 18 A). Thoracic endopods 3–8 with 3–6-segmented carpopropodus, dactylus small, with distinct, in part seta-like claw (Fig. 18 E–L); dactylus of endopod 8 flanked by a pair of minute paradactylar lobes (Fig. 18 K) in both sexes. All female pleopods and male pleopods 1, 2, 5 reduced to setose rods (Fig. 18 O). Male pleopod 3 reduced to well-developed, two-segmented sympod terminally fused with its small, setose, unsegmented endopod, exopod missing (Fig. 18 M). Male pleopod 4 (Fig. 18 N) biramous with 2-segmented sympod, with small, 2-segmented endopod, and with large, 3-segmented exopod bearing a modified seta at tip and a very long smooth seta at penultimate segment; seta from the penultimate segment extends far beyond the seta from the apical segment (Fig. 18 N). Endopod of uropod setose all around, with only one spine below statocyst. Telson with small apical cleft; with spines on each lateral margin, these margins ending in a pair of large, posteriorly directed apical spines; cleft lined by a number of laminae (Fig. 18 S, T).
