Espèce Sensiava peculiaris - Planche 1 de figures morphologiquesIssued 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).

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.

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. Basis with 3 proximal setae and 2 distal setae. Endopod 5-segmented with setal formula 4, 4, 3, 3+1, 4.
