The new species is most similar to B. venatrix (O. Pickard-Cambridge, 1874) and B. koponeni Marusik, Fomichev & Omelko, 2014 by having a broad embolar base (Eb) with a similar sclerotized apical outgrowth (Ao) parallel to a bent, long embolus and a basal process (Po). In the new species, the two
elements of the embolar base are pointed (vs shallowly divided with the process small and curved in B. koponeni; see Marusik et al. 2014: figs 32, 34, and the basal process bearing a very pointed sclerotized tooth in B. venatrix; see Levy 1995: fig. 57, not present in B. artaxerxes sp. nov.). Also, the median apophysis in B. artaxerxes sp. nov. is bent prolaterally and located under the apical outgrowth’s curve (vs straight and longer, reaching the height of the embolus in B. koponeni; see Marusik et al. 2014: figs 34–35).
The specific epithet is a noun in apposition and refers to Ardashir I (equivalent to Greek Artaxérxēs), the founder of the Sasanian Empire.

Measurements of legs: I: 7.00 (1.95, 1.12, 1.54, 1.31, 1.08), II: 6.29 (1.68, 1.08, 1.24, 1.26, 1.03), III: 5.04 + missing Ta (1.62, 0.99, 0.94, 1.49, Ta missing), IV: 8.58 (2.25, 1.20, 1.49, 2.39, 1.25).
Palp as in Fig. 3B–D. Tibia with massive apophysis, as long as tibia, pointed tip directed dorso-anteriorly with angle about 45° to the axis of the palp; cymbium ovoid, 1.6 times as long as wide; median apophysis long, oblique, about as long as tibial apophysis; embolar base (Eb) complex, with 2 outgrowths: a basal pointed process (Po) weakly sclerotized, and a sclerotized apical outgrowth (Ao) [tip appears broken] parallel to a bent, long embolus; embolus proper gently curved and making a course of about 90°.
