| | | | | | Ref.: | | | Chen & Zhang, 1965 (p.42, 123, Descr.F, figs.F); Zheng & al., 1982 (p.621, figs.F); Kesarkar & Anil, 2010 (Rem.: p.404, fig.H); Soh & al., 2013 (p.67, figs.F) | issued from: Q.-c Chen & S.-z. Zhang in Studia Marina Sinica, 1965, 7. [Pl.9, 13-15]. Female (from E China Sea): 13, habitus (dorsal); 14, idem (lateralleft side); 15, P5 (posterior). Nota: Rostrum rather robust, without terminal filaments. - Head and 1st thoracic segment fused, 4th and 5th fused. - Proportional lengths of cephalothorax and abdomen: 82 : 18. - Posterolateral angles of last thoracic segment smoothly rounded, not very protuberant. - Abdomen 4-segmented. - A1 (24-segmented) extending about 2 segments beyond the furca. - Exopod of A2 shorter than endopod. - Exopod of P1 3-segmented, endopod 2-segmented; 1st exopodal segment with a small outer marginal spine, 2nd segment without such a spine, 3rd segment longer than preceding segment, its outer middle edge with a small seta, the length of which reaches the base of the terminal seta. - Exopod and endopod of P2 to P4 each with 3 segments. Spinules on the outer proximal margin of 3rd exopodal segment of P2 to P4, 5-6, 8-11, and 7-8. - P5 with 2 segments, 1st longer than the 2nd which has 2 apical spines, the inner spine with denticulate outer distal margin and about 4 times as long as outer spine. The abdominal segments and furca in the proportional lengths 32 : 12.5 : 12.5 : 21.5 ; 21.5 = 100. - Genital segment (nearly globular) wider than long and longer than length of the two following segments combined together. - Anal segment longer than preceding segment. - Furcal rami 1.5 times as long as wide.
