issued from : Q.-c. Chen & S.-z. Zhang in Studia Marina Sinica, 1965, 7. [Plate 26].
Female (from Chou-San archipelagoes): 1, habitus (dorsal view); 2, head (lateral view); 3, Th5 and urosome (lateral view); 4, P5 (posterior view).
Nota: Head and 1st thoracic segment fused, 4th and 5th separate.
- Rostrum with a long filament.
- Posterolateral angles of last thoracic segment , pointed and asymmetrical; right cone slightly larger than the left.
- Urosome 3-segmented.
-
- Genital segment with right side swollen, provided with numerous fine denticles.
- Anal segment, smaller than preceding segment.
- Furcal rami asymmetrical, the left longer than the right.
- A1 24-segmented, extending beyond the end of last thoracic segment; P5 asymmetrical, inner spine of 2nd exopodal segment with denticulate outer and inner margin, longer than the length of 1st and 2nd segments combined but shorter than the distal segment.

Male: 5, habitus (dorsal view); 6, 3rd exopodal segment of P4 (posterior view); 7, P5 (posterior view).
Nota: Postero-lateral angles of last thoracic segment small and symmetrical.
- Uosome 4-segmented; 2nd segment longest.
- Right A1 geniculate, 21 -segmented; upper margin of 18-19th segments, serrate distal segment with spine as long as its length. P1-P4 of left side larger than those of the right side. 2nd outer marginal spine of 3rd exopodal segment of right P4 longer than that of left P4; 3rd outer marginal spine of right 3rd exopodal segment hook-like and curved outwardly, outer marginal denticles of apical spine smaller than those of the left side.
- P5 asymmetrical; exopod of left foot, 2-segmented, 2nd segment longer than the 1st. Exopod of right foot 3-segmented, 2nd segment broadest, ventral margin of its inner spine serrate (with about 7-8 teeth), distal segment with a soine on both sides, apical spine, strong and smooth, its disrtal portion curved outwardly.

Nota: Right A1 gencilate, anterior margin of segment 17 with rows of denticles from proximal 1/3 from distal end; segment 18 wih short row of denticles; distal segment armed with long, spur-like process. P1-P4 of left side longer than those of right side; outer seta of exopod 2 of right P4 longer than of left P4.; outer seta of right exopod 3 hook-like and curved outwards, outer marginal denticles of apical spine smaller than those of the left side.
