| | | | | | | Ref.: | | | Ohtsuka, El-Sherbiny & Ueda, 2000 (p.2, figs.F,M) |  issued from : S. Ohtsuka, M.M. El-Sherbiny & H. Ueda in Crust. Res., 2000, 29. [p.3, Fig.1]. Female (from N Red Sea): A, habitus (dorsal); B, idem (lateral right side); C, urosome (lateral right side); D, idem (dorsal); E, spermatophore attached to urosome (dorsal, attachment disc indicated by shaded part); F, idem (lateral left side, idem); G, Md (mandibular palp); H, maxillary basis and endopod; I-J, P5 (anterior. A-C, G-I : holotype; D-F, J: paratypes. Nota: Urosome 2-segmented. Genital compound somite with sinouos lateral margins, bearing small round knob with minute peg-sensillum on left side at midlength; Subterminalportion of compound somite constricted (possibly indicating secondary fusion between genital compound somite and 2nd original urosomite in former stage). Anal somite almost fused to caudal rami (with suture distinctly visible). Mandibular exopodal segments almost fused, with 4 transverse rows of spinules. The expansion of the left caudal ramus more or les varies between individuals

 issued from : S. Ohtsuka, M.M. El-Sherbiny & H. Ueda in Crust. Res., 2000, 29. [p.4, Fig.2]. Male: A, habitus (dorsal); B, urosome and P5 (lateral right side); C, right A1 (terminal part); D, P5 (anterior); E, right P5 (posterior). Nota: head and 1st thoracic segment separate, 4th and 5th fused. Urosome 5-segmented. Genital somite slightly asymmetrical (left posterior side more expanded than right). 2nd urosomite with 2 ventrolateral pointed protuberances on right side, each bearing peg-sensillum. Anal somite almost completely coalescent with caudal rami but with distinct suture.
