Legs. Fore leg: coxa bare on anterior and posterior surfaces; tibia with 1 posterior seta; preapical anterodorsal seta much shorter than preapical dorsal seta, preapical posterodorsal seta absent; tarsomere 1 about twice as long as tarsomere 2 and 0.35 times as long as tibia; claw nearly as long as tarsomere 5. 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 and about half as long as wide; tergites 4–5 each with a nearly complete row of marginal setae; tergite 5 about 0.8 times as long as tergite 4; sternites 2–4 visible, partly overlapped by ventral edges of tergites. Terminalia. Sternite 5 with a V-shaped median apical depression including a few microscopic spines on its inner side apically, without sensilla trichodea ( Fig. 3 ); surstylus distinctly narrowed in apical third and shorter than cercus (lateral view); cercus tapered, with a forward bend apically ( Fig. 4 ); cercus in dorsal view pointed at tip ( Fig. 2 ); distiphallus membranous ventrally, weakly sclerotized dorsally ( Figs 5–7 ).

Female. Same as male except as follows: fronto-orbital plate covered with whitish-grey microtrichosity; 2 proclinate lower orbital setae; tergites 3–4 without a blackish narrow longitudinal stripe dorsomedially (posterior view).

Etymology. The name ‘ breviaristata ’ (Latin, adjective) is derived from ‘brevi’ (short) and ‘aristata’ (having an arista), in reference to the short first aristomere.

Distribution. Iran.
