| | | | | | | Ref.: | | | Markhaseva & Schulz, 2007 (p.743, figs.F) |  issued from : E.L. Markhaseva & K. Schulz in J. Nat. Hist., 2007, 41 (13-16). [p.743, Fig.8] Female (60°38'S, 53°57'W): A, habitus (dorsal); B, anterior part of cephalosome (lateral); C, rostrum (ventral); D, posterior prosome and urosome (lateral); E, posterior prosome and genital double-somite (right lateral); F, urosome (dorsal); G, genital double-somite (ventral); H, anal somite and caudal rami (ventral; setae partly detached). Scale bars: 0.1 mm. Nota : Prosome about 4.6 times longer than urosome. Rostrum witout filaments. Cephalosome and pediger 1 separate, 4th and 5th separate. Right posterior corner of prosome rounded with small knob ventrally. In dorsal view, genital double-somite slightly swollen at mid-length, lateral surfaces with denticles, spermathecae small, oblong. Caudal rami with 4 terminal setae, 1 small dorsal and 1 small ventral seta.
