Etymology. The specific name is derived from the Latin word “ resimus ”, meaning “with upturned nose”, and refers to the shape of sclerotized lateral lobe edges and BO of epigynum; adjective.

Diagnosis. Females of this new species appear almost identical to B. punctosparsa (Song, Zhu & Chen, 1999: 363, figs 213K–N), but can be distinguished by the detailed structure of epigynum.

Description. Female (holotype). Total length 3.80 ( Figs 37C–D View Figure 37 ). Prosoma length 1.75, width 1.20. Cephalic region width 0.70. Cephalic part flat, covered with several setae. Thoracic part brown, fovea reduced, prosoma margin indistinct. Eight eyes, AME black, others white, all eyes encircled with black. Eye diameters: AME 0.04, ALE 0.10, PLE 0.10, PME 0.08. Eye interdistances: ALE-PLE 0.03, AME-ALE 0.04, AME-AME 0.05, PLE-PME 0.07, PME-PME 0.10. Eye region length 0.21, width 0.74. Clypeus height 0.13. Chelicerae length 0.65, width 0.33. Chelicerae brown, with distinct lateral condyles, 3 (1 large, 2 small) promarginal and 5 retromarginal teeth. Labium and gnathocoxae brown, sternum light brown. Labium length 0.19, width 0.28.
