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.
