Remarks

Characters female after Rosendorn (1917 a, p.48): Proportion of lengths (p.cent) Prosome : 58.54, Urosome : 41.46 . Relative lengths of urosomal segments and caudal rami8 : 9 : 30 : 15 : 14 : 12 : 12. Setal formula of the exopod swimming legs P1 to P4 (Se = outer setae ; Si = inner setae), P1 : 1, 1, 2 Se ; 0, 1, 4 Si ; P2 : 1, 1, 2 Se ; 0, 1, 5 Si ; P3 : 1, 0, 1 Se ; 0, 1, 5 Si ; P4 : 0, 0, 1 Se ; 0, 1, 5 Si. We observe differences in the setal formula compared to Nishida & al. (1977).
