Metapectal-propodeal disc with strong transverse posterior keel, dull, reticulate rugose; propodeal declivity dull, with two complete longitudinal keels, lateral areas completely reticulate rugose and median area partly shiny and unsculptured. Forewing hyaline, without dark transverse bands; 2r-rs&Rs vein regularly curved with no distinct separation between distal and proximal part; 2R1 cell open. Apex of basivolsella without subdistal inner pointed apophysis (Fig. 108D). Tibial spurs 1/1/2.

Remarks. ♀♀ of B. hyalinus show two varieties based on colour and sculpture as follows: variety A (very light and slightly sculptured): as represented by the holotype, in a specimen from Oman, Al-Uyaina–Samail, and in almost all known specimens from the UAE (except for a specimen from 25°24’N 56°17’E); variety B (dark and strongly sculptured): known in a specimen from the UAE, 25°24’N 56°17’E, and in a specimen from Kenya, 0.82103°S 38.54443°E.
