| | | | | | Ref.: | | | Markhaseva, 2014 (p.228, Descr.F, figs.F); Laakmann & al., 2019 (p.330, fig. 2, 3, 4, phylogenetic relationships) | Issued from : E.L. Markhaseva in Zootaxa, 2014, 3802 (2). [p.229, Fig.9]. Female (from G. of Guinea largo sensu): A-B, habitus (dorsal and lateral, respectively); C, rostrum (dorsal view); D, same (lateral); E-F, posterior prosome and urosome (dorsal and lateral, respectively); G, genital field (lateral view). Scale bars: A-B, 0.5 mm; C-H, 0.1 mm. Nota: Prosome 3.7-4.1 times as long as urosome. Rostrum as 2 filaments. Cephalosome and 1st pedigerous somite invompletely separate, 4th and 5th completerly separate. Posterior corners of prosome in dorsal view trianguylar; as short rounded in lateral view. Urosome of 4 somites. Spermatheca elongate, narrow and rounded distally, directed anteriorly. Caudal rami with 1 dorsal, 1 ventral and 4 terminal setae.

Scale bars: 0.1 mm. Nota: Mx2: praecoxal endite (anteriorly as proximal praecoxal endite) with 4 setae and 1 small attenuation; coxal endite (anteriorly as distal praecoxal endite) with 3 setae; basal endites (anteriorly as coxal endites) with 3 setae each, 1 seta of proximal basal endite sensory, worm-like; enditic-like lobe of proximal endopodal segment (anteriorly as proximal basal endite) with 4 setae (2 sensory and worm-like); setae of the maxilla basal endites and enditic-like lobe of endopod are similar in shape and size, curved distally: endopod with 3 worl-like and 5 brush-like sensory setae. Mxp: syncoxa with 1 sclerotized seta on proximal endite, 1 worm-like and 1 sclerotized setae on middle praecoxal endite and 2 sclerotized and 1 worm-like setae on distal praecoxal endite; coxal lobe with 3 setae.
