Male (from Sulu Sea): A-B, habitus (dorsal and lateral, respectively); C, rostrum (anterior; right rostral filament missing); D, F, right distal corner of prosome (dorsal and lateral, respectively); E, G, left distal corner of prosome (dorsal and lateral, respectively); H, left caudal ramus (dorsal); I, A2 exopod (setae omitted); K, terminal portion of A2 endopod. Scale bars in mm. Nota : Body relatively weakly chitinized expcept for P5. Prosome about 2.3 times as long as urosome. Cephalosome produced posterolaterally to cover anterior part of 1st pediger. Rostrum produced posteriorly, with pair of long filaments. 5th pediger produced posteriorly at each side into irregular processes furnished with glandular openings and hair-like sensillae ; posterior margin of processes fringed with fine setules. large spermatophore visible, extending from 1st pediger to genital somite. Urosome 5-segmented.Genital somite with gonopore opening at right posterolateral corner. 2nd and 3rd urosomites almost equal in length. Anal somite relatively conspicuous. Caudal rami symmetrical, fringed with long setules on both sides ; rudimentary seta I present, seta V longest. A2 with unarmed coxa ; basis with inner seta terminally; endopod 2-segmented, 1st segment unarmed, 2nd segment with 3 inner setae of unequal length and 1 reduced and 5 well-developed terminal setae; exopod indistinctly 7-segmented, setal formula 0, 1, 1, 1, 1, 1, 3 (1 vestigial).

Right A1 23-segmented, reaching to anal somite seta terminally ; Md with 2 mono- and 1 tricuspid teeth and 2 patches of setules along cutting edge ; patch of long setules present near base of palp ; endopod absent, but possibly represented by round prominence ; exopod 5-segmented, setal formula 1, 1, 1, 1, 2. Mx1 with praecoxal arthrite bearing 5 serrate spines and 1 process ; coxal endite with 1 serrate seta ; coxal epipodite with 8 setae (2 of which relatively short) ; basis with rows of long setules and vestigial seta ; endopod 1-segmented, bulbous, with 2 serrate unequal setae ; exopod 1-segmented, lobate, with 3 long setae terminally.
