Ohtsuka & C. Mitsuzumi in Bull. Plankton Soc. Japan, 1990, 36 (2). [p.89, Fig.1]. Female (from Tanabe Bay): A, habitus (dorsal); B, rostrum ventral view); C, 5th toracic segment (lateral right side); D, 5th thoracic segment with P5 and urosome (lateral left side); E, F, urosome (ventral; copulatory pores indicated by arrows; E: holotype, F: paratype); G, left A1 (all elements omitted); H, right A1 (all elements omitted); I, right A2; J, left A2. Nota: Prosome considerably asymmetrical with left side compressed and right one smoothly curved in dorsal view. Head and 1st thoracic segment separated, Th4 and Th5 fused. Urosome 4-segmented. Genital segment asymmetrical, with right ventro-lateral and left ventral oviduct openings; copulatory pore located on left ventro-lateral side. left A1 longer than right; both 21-segmented. Antennae 2 asymmetrical. Md symmetrical

 issued from : S. Ohtsuka & C. Mitsuzumi in Bull. Plankton Soc. Japan, 1990, 36 (2). [p.92, Fig.4]. Male: A, habitus (dorsal); B, idem (lateral left side); C, left A1 (all elements omitted); D, right A1 (all elements omitted); E, F, P5 (anterior view; E: paratype, F: allotype). Nota: Prosome asymmetrical as in female. Urosome 5 segmented. Left A1 geniculate, 20-segmented (segments 16 and 17 bearing low lamella along anterior margin, segment 18 with 2 low lamellae anteriorly, terminal 2 segments incompletely fused, articulation between segments 17 and 18; right A1 21-segmented. Remarks: Legs 5 of both sexes vary morphologically.

 issued from : S. Ohtsuka & C. Mitsuzumi in Bull. Plankton Soc. Japan, 1990, 36 (2). [p.94, Pl. I]. Four types of integumental organs of the cephalothorax (SEM photomicrographs). Scale bar = 0.005 mm. A, B: Divergent-hair sensillum; C, single-hair sensillum; D, three types of integumental organs: Ip = circular pore; sp = circulal pore, small type; hs = single-hair sensillum.

 issued from : S. Ohtsuka & C. Mitsuzumi in Bull. Plankton Soc. Japan, 1990, 36 (2). [p.95, Fig.5]. Female: shematic illustration of the location of 4 types of integumental organs on cephalothorax (lateral views: A, left side; B, right side). white o: circular pore (small type); black o: circular pore (large type); white triangle: divergent-hair sensillum; black triangle: single-hair sensillum.

 issued from : S. Ohtsuka & C. Mitsuzumi in Bull. Plankton Soc. Japan, 1990, 36 (2). [p.96, Fig.6]. Female: Schematic illustration of the location of 4 types of integumental organs on cephalothorax (dorsal view). A: dorasl view (median line indicated by broken line; B, postero-dorsal view of pediger 5; G, genital segment; P, pedigers 4 and 5. Symbols the same as in Fig.5.

 issued from : S. Ohtsuka & C. Mitsuzumi Bull. Plankton Soc. Japan, 1990, 36 (2). [p.98, Fig.7]. Schematic illustration of the swimming position with the compressed left lateral side parallel to the bottom. A, B, position of the urosome in swimming and resting, respectively.
Nota: The asymmetrical parts of the copepod body seem to be adapted for the behavior in its habitat. The gut content analysis revealed that the copepods fed carnivorously on epibenthic harpacticoids.
