El Sherbiny & H. Ueda in Org. Divers. Evol., 2010, 10. [p.25, Fig.2]. Female (from N Red Sea): a-b, habitus (dorsal and lateral, respectively); c, forehead (lateral); d-e, urosome (dorsal and ventral, respectively); f, A1; g, A2; h, Md (mandibular gnathobase). Scale bars in mm. Nota: Cephalosome without lateral hooks. A pair of dorsal lenses. Urosome 2-segmented. Genital double-somite asymmetrical, with pointed process middorsally; genital operculum located on left ventrolateral side. Anal segment very short. Caudal rami symmetrical; each ramus with 5 plumose setae and small dorsal seta. A1 23-segmented, not extending beyond 3rd pedigerous somite; posterior margins of segments 2-13 fringed with fine hairs. A2: coxa with 1 plumose seta posteriorly; basis fused to 1st endopodal segment carrying 2 setae proximally and 2 setae distally; 2nd endopodal segment lamellar, produced into 2 lobes with 9 and 8 setae, respectively; exopod 5-segmented with setal formula 0, 2, 1, 2, 5.
