Diagnosis

Males of this species differ from all congeners by the tibial apophysis being rectangular with a blunt end (vs with tapering tip) and by the distinct form of the median apophysis (= conductor sensu Panayiotou et al. 2010), with the sclerotized part directed terminally (vs laterally in B. aegilia Chatzaki, 2002 and B. amabilis Roewer, 1928 or hook-like in B. ensigera (O. Pickard-Cambridge, 1874) , B. cooki Logunov, 2012 , B. cypria Chatzaki & Panayiotou, 2010 and B. hakani Chatzaki & Seyyar, 2010 ). Females of B. hoerwegi sp. nov. are mostly similar to those of B. aegilia but can be distinguished by the smaller conical anterior hood (Ah) (vs rectangular) and longer copulatory ducts.

Etymology

This species is named after Mr Christoph Hörweg, the curator of Arachnology at NHMW, for helping the first author during his visit to Vienna.

Palp as in Fig. 2B–G . Femur unmodified; patella slightly longer than tibia (not including apophysis); tibial apophysis as long as tibia, with swollen base and flat anterior part, margins parallel; cymbium 2 times as long as wide, its width as long as tibia; spermophor coiled; median apophysis (= conductor sensu Panayiotou at al. 2010) large, sharply pointed; filamentous embolus originates almost from the center of the bulb, makes 360° loop.

Distribution

Known from the listed localities in Ilam, Kermanshah, Kurdistan and Fars Provinces, western and southcentral Iran.
