Comments. In the structure of the epigyne (with tightly clustered epigynal teeth), females of B. nenilini resemble those of B. turkestanicus . They differ by the shape of the epigynal fovea (Fo) with wide (vs. narrow) median constriction, as well as by the shape and arrangement of the receptacles which are narrower and more widely spaced in the middle part vs. narrowly spaced ( Figs 10, 11 cf. Fomichev 2021, fig. 1D–F). Males of B. nenilini differ from other known male congeners, except for B. juglandicola , in possessing the bifurcated (vs. undivided) retrolateral patellar apophysis of the male palp; they can be distinguished from the latter species by the different shape of the conductor and median apophysis of the tegulum (Ovtchinnikov 1984, fig. 1; 1999, figs 35, 37, 40–42; Wang & Zhu 2009, figs 10, 22,30; Dimitrov & Jager 2021, figs 1, 2).

Distribution. The species is known from several localities in the forested midlands of Western Tien-Shan ( Uzbekistan).
