Diagnosis. Males of B. ovchinnikovi sp. nov. are similar in general appearance and shape of the palpal structures to those of B. vignai but differ from them by a relatively longer tip of the cymbium, which is about 1.7 times longer than wide ( vs. as long as wide), and by having 7 strong macrosetae on the cymbial tip ( vs. 4), as well as by possessing a horizontally stretched ( vs. antero-retrolaterally extended) conductor, with a shorter ( vs. longer) distance between its dorsal and retrolateral parts, a narrower ( vs. wider) embolus base, and a blunt ( vs. pointed) tip of the patellar apophysis (Please refer to figure for both species see Figs 16–23 View FIGURES 15–20 View FIGURES 21–23 and Dimitrov & Jäger 2021, figs 1, 2, respectively). Females of the new species are most similar to those of the Lebanese B. caudatus in having similarly shaped epigyne with long teeth ( Et), and similar shape of fovea. It can be distinguished by spaced bases of teeth ( vs. not spaced), by a longer fovea with anterior margin ( Am) located close to the teeth bases ( vs. anterior margin spaced from the teeth bases by about 0.5 of the fovea length), and by a thinner anterior margin, which as wide as span of teeth ( vs. wider than span of teeth) (Please refer to figure for both species see Figs 25–27 View FIGURES 24–27 and Wang & Zhu 2009, figs 4, 5, respectively).

Bulb ( Figs 21–23 View FIGURES 21–23 ) slightly longer than wide; tegulum ( Te) almost entirely hidden in ventral view by base of embolus, base of conductor ( Cb) and tegular apophysis ( Ta); tegular apophysis large, almost 2 times longer than wide, not flexible; conductor ( Co) with one arm trifurcated on tip; embolus with large base ( Eb) wider than base of conductor, filamentous part of embolus originates at ca. 7 o’clock position.
