Brevistoma gallagheri Hölzel, 1999: 136 (type locality: Oman, Wahiba Sands; holotype in NHMW). Güsten, 2003: 137 (Brevistoma). Sziráki, 2011: 66 (Brevistoma).
Diagnosis. Vertex barely raised, generally brown. Male antenna nearly 1/3 length of forewing. Pronotum medially with a slender grey brown stripe, laterally with a pair of greyish brown markings. Mesoprescutum greyish brown, laterally yellowish brown; mesonotum generally yellowish brown; mesoscutellum yellowish brown, medially with a greyish brown marking. Forewing generally hyaline; subcostal area hyaline. Hind wing mostly hyaline, distal part of hind wing with two brown marking. Male posterior gonocoxites 9 trapezoid falcate and curved internally, internal projection of posterior gonocoxites 9 obliquely protruded in lateral view; gonostyli 11 subtriangular in dorsal view.
Re-description. Size. Head width, 1.92 mm; forewing length, 15.26 mm; hind wing length, 30.15 mm.
Head. Generally brown. Vertex barely raised. Male antenna brown, covered with many short-tapered setae, nearly 1/3 length of forewing. Each flagellomere wider than long in male (Fig. 11D). Male frons nearly half as long as wide. Male clypeus brown, as long as wide. Labrum brown, truncated on distal margin. Maxillary palpus columniform. Labial palpus slender. Cardo and stipe pale brown. Mandible brown, elongate. Rostrum nearly as long as half of head width (Figs 6D–E).
Thorax. Pronotum medially with a slender grey brown stripe, laterally with a pair of grey brown markings. Mesoprescutum grey brown, laterally yellowish brown; mesonotum generally yellowish brown; mesoscutellum yellowish brown, medially with a grey brown marking. Meso- and metapleurae generally pale yellow (Fig. 6D).
Legs. Slender, generally pale yellow. Tibial spur weakly developed. Tarsomeres 2–4 with some stout setae ventrally; pretarsal claws dark reddish brown, slightly curved (Fig. 6C).
Wings. Forewing generally hyaline, apex rounded; pterostigma pale; costal crossvein not forked; 11–12 presectoral crossveins present; RP with four branches; 3A not closed to forewing margin. Hind wing slender, ribbon-like, nearly twice as long as forewing, mostly hyaline; distal part of hind wing with two dark brown markings; pterostigma pale (Figs 1C; 6A–B).
Abdomen. Brown to greyish brown. Male genitalia. Sternum 9 nearly twice as long as ectoproct, rectangular in ventral view, covered with some slender setae (Fig. 6F). Anterior gonocoxites 9 short, nearly as long as gonostyli 11 in lateral view, V-shaped in ventral view; posterior gonocoxites 9 trapezoid falcate and curved internally, internal projection of posterior gonocoxites 9 obliquely protruded in lateral view; gonostyli 11 swollen, subtriangular in dorsal view, slender and upward in lateral view (Figs 6H–L). Ectoproct subtriangular in lateral view (Fig. 6G). Female genitalia. Unknown.
