| | | | | | | Ref.: | | | Ohtsuka & Conway, 2005 (p.66, figs. F,M); Francis & Bijoy Nandan, 2019 (p.433, Table 4, 5). |  issued from : S. Ohtsuka & D.V.P. Conway in J. Mar. Biol. Ass. U.K., 2005, 85 (1). [p.67, Fig.2]. Female (from mahé, Seychelles): A-B, habitus (dorsal and lateral, respectively); C-D, posterior prosome and urosome (dorsal); E, genital compound somite (dorsal); F-G, postrior prosome and urosome (right and left lateral view, respectively); H, genital compound and anal somites (ventral); I, P5 (posterior); J, phoront of apostome on intercoxal sclerite of P4. Scale bars in mm. Nota: Cephalosome and 1st pediger separate, 4th and 5th fused. Cephalosome protruded anteriorly into round expansion in which naupliar eyes involved and strongly grooved at dorsal mid-length. Posterior prosome slightly asymmetrical, with right side more swollen. P5 with both coxae and intercoxal sclerite completely fused to form common base; exopod unidegmented, left slightly lionger than right, each with 1 inner middle and 2 terminal, acutely pointed processes, terminal processes unequal on left but almost equal on right.
