| | | | | | | Ref.: | | | Markhaseva & Schulz, 2008a (p.280, figs.F) |  issued from : E.L. Markhaseva & K. Schulz in Zootaxa, 2008, 1866. [p.281, Fig.1]. Female (from Antarctic): A-B, habitus (dorsal and lateral, respectively); C, rostrum (lateral); D, forehead with rostrum (ventral); E, posterior corners of prosome (dorsal); F, urosome (dorsal); G, same (lateral); H, posterior corners of prosome and genital double-somite (lateral); I, same (lateral); K, genital double-somite (ventral). Scale bars 0.1 mm. Paratype: C, E-G; other figures: holotype. Nota : Prosome 1.3-1.5 times as long as urosome. Rostrum as an elongate cone. A1 25-segmented (segments 24-25 incompletely separate). Genital double-somite symmetrical. Caudal rami asymmetrical ; right ramus nearly twice as long and wide as left ; both rami with 4 terminal setae ; right ramus with a small mediodorsal seta, ventral seta lacking ; left ramus with a small medioventral seta, dorsal seta lacking.
