Mid leg: tibia with 1 strong anterodorsal, 2 posterior and 1 ventral setae. Hind leg: tibia with a nearly complete row of anterodorsal setae, 2–3 anteroventral and 3 preapical dorsal setae, preapical anterodorsal and preapical dorsal setae equal-sized and strong, preapical posterodorsal seta short and fine; preapical posteroventral seta absent.

Abdomen. Middorsal depression of syntergite 1+2 extending to posterior margin; syntergite 1+2 with a pair of median marginal setae; tergite 3 with 1 pair of median marginal setae and 1 pair of lateral marginal setae, tergite 3 about half as long as wide; tergites 4–5 each with a nearly complete row of marginal setae; tergite 5 about 0.9 times as long as tergite 4; sternites 2–4 visible, partly overlapped by ventral edges of tergites. Terminalia. Sternite 5 with a wide, U-shaped median apical depression including a few microscopic spines on its inner side apically, without sensilla trichodea ( Fig. 11 ); surstylus semi-triangular, abruptly narrowed apically and shorter than cercus (lateral view); cercus tapered, with a forward bend in lateral view ( Fig. 12 ); cercus in dorsal view curved inwards in approximately apical third ( Fig. 10 ); distiphallus entirely membranous ( Figs 13–15 ).

Distribution. Iran, Israel, Transcaucasia ( Tschorsnig 1983; Richter 1991; Cerretti & Freidberg 2009).

Remarks. Hans-Peter Tschorsnig (SMNS) examined the external morphology and sternite 5, cercus, surstylus and the aedeagus of the Nakhichevan specimens of Bampura at SMNS, and confirmed that they belong to B. angustigena . He also affirmed that the description of the male corresponded with the studied Nakhichevan specimens.
