Barbier leg. ( LECA ; Ps-SCR010) . Diagnosis. According to Ellingsen (1905) and Beier (1932b) can be easily distinguished from the other species of the genus Parachernes Chamberlin (1931) by the carapace as long as broad 1.14×, gradually narrowing forwards, the short frontal margin straightened. Metazone distinctly granulated, yet a little glossy before the first furrow. Two distinct transverse furrows, the anterior one about in the middle, the posterior one somewhat nearer to the hinder margin than to the anterior furrow. Tergite divided (except XI), slightly granulated, al setae rather long, slightly clavate. Chaetotaxy tergal: 10: 10: 10: 8(1): 8(2): 6(2): 8(2): 8(2): 8(2): 10(2): 4(2ST):2. Genital region opercula with a central group of 18 short, three setae on each side, and ten marginal setae. Chelicerae, female with galea very slender and short, with some fine teeth in and near the extremity on the underside, male with about 6 terminal branches; paired spermatheca, typical of the genus. Pedipalps moderately strong, all segments smooth and glossy. The setae on the inner side of the trochanter and femur are slightly clavate, the other setae of the palps are slightly dentate in the extremity, on the fingers simple with some longer ones intermixed; trochanter and the proximal part of femur slightly shagreened; femur 2.35×, strongly granulated; patella 2.02×, more slightly, rather shagreened. chela with pedicel 3.18×, chela without pedicel 2.47×, hand round about smooth and very glossy, fingers as general smooth and glossy. Measurements (mm). Body length: 2.359. Carapace: 0.771 / 0.672 . Pedipalps: trochanter: 0.347 / 0.197 , femur: 0.544 / 0.235 , patella: 0.589 / 0.266 , chela with pedicel: 1.064 / 0.384 , chela without pedicel: 0.950 / 0.384 , movable finger: 0.538.
