| | | | | | | Ref.: | | | Markhaseva & Ferrari, 2005 a (p.139, Descr.F, figs.F, tab.2, Rem.) |  issued from : E.L. Markhaseva & F.D. Ferrari in Invert. Zool., 2005, 2 (2). [p.140, Fig.16]. Female (from 9°50'N, 104°17'W): A, posterior prosome and urosome (lateral, left side); B, posterior prosome (dorsal); C, anterior cephalosome (lateral); D, forehead (dorsal); E, urosome (dorsal); F, A2 (5 segments of exopod); G, P1 (anterior); H, right P5 (posterior). Scale bars: 0.1 mm. Nota : Prosome 3.8 times longer than urosome. Cephalosome and pediger 1 fused, 4th and 5th fused dorsally, separate laterally. Postrior corners of prosome produced into short, rounded lobes in lateral view. Genital complex slifgtly asymmetrical in dorsal view, in lateral view with bump at midlength ; with small spinules dorsally and laterally. Rostrum with 2 thin short filaments. A1 24-segmented. P5 3-segmented ; proximal and middle segments (coxa and basis) with denticles ; distal segment (exopod) with 1 short, lateral, 1 terminal and 1 medial setae and 1 long terminal attenuation, with posterior denticles. P1 coxa without seta ; basis with medial seta ; exopod 3-segmented, proximal with 1 lateral seta, middle with 1 medial and 1 lateral seta, distal segment short with 3 medial, 1 terminal, 1 lateral seta ; endopod elongate ; Von vaupel Klein’s organ with basal seta uncurved, anterior knob poorly developed with denticles along lateral edge distal to anterior knob.
