 issued from : O. Tanaka in Publ. Seto Mar. Biol. Lab., 1957, VI (1). [p.57, Fig.35]. As Chiridiella macrodactyla. With doubt. Female: a, forehead (lateral); b, last thoracic segment and urosome (lateral left side); c, urosome (ventral); d, Md (mandibular palp); e, Mx1; f, Mx2; g, P1. Nota: Head and 1st thoracic segment fused, 4th and 5th fused. Rostrum absent. Proportional lengths of urosomites and furca 40:12:12:12:20:16 = 100. Furcal rami wider than long, carries short setae. A2 has 7-segmented exopod which is 1.23-times as long as endopod.

Fauna SSSR, 1950, 35 (Israel Program for Scientific Translations, Jerusalem, 1967) [p.194, Fig.109].

Scale at left for parts a and b; at lower right for parts c-f. Scales in mm. Nota : Head and 1st thoracic segment separate. Cephalothorax 82-83 % of total length. Urosome about 21 % of cephalothorax length. Genital segment very protuberant ventrally. A1 24-segmented, not longer than cephalothorax. Endopod of A2 ¾ length of exopod.

Male: a, habitus (lateral); b, A2; c, Md; d, left A1; e, Mx1; f, left P5; g, right P5; h, P3 (exopod segments 2 and 3 missing); i, P2; j, Mx2; k, Mxp (endopod setae not shown). Scale on left margin for parts a; on right margin for parts b-k. Scales in mm. Nota : Md and Mx2 greatly reduced (suggesting that the male does not eat after his final molt.
