Pachyanthrax mogyi View in CoL sp. nov.

( Figs 1–2, 8–11 View FIGURES 1–11 , 14 View FIGURES 12–18 )

This species is characterized by the silky white hairs and white long scaly hairs densely covering the thorax and abdomen.

Etymology. The patronymic name mogyi is proposed in honor of my colleague and friend Prof. Dr Mohamed El-Mogy, Entomology Department, Faculty of Science, Cairo University, Egypt.

Description. Male (Holotype) ( Fig. 14 View FIGURES 12–18 ). Relatively large species, body length: 12 mm, wing length: 10 mm. Head. Black in ground colour, ocellar tubercle dark brown; upper frons narrow, slightly wider than ocellar tubercle; frons and face densely covered with long white and yellowish-white scales and scaly hairs become brownish at margins of face, mixed with numerous brownish and black hairs; proboscis dark brown, short, not protruding the oral cavity; scape and pedicel ( Fig. 1 View FIGURES 1–11 ) yellowish-brown, with long whitish hairs mixed with some brownish and black ones; flagellum black, conical; scape 3 times as long as pedicel, flagellum 1.5 as long as scape and pedicel together, slightly constricted at middle, with a short second flagellomere and a tiny terminal spine-like style; occiput densely covered with long white scales. Thorax. Scutum black in ground colour, with the post alar callus dark brown, covered with long whitish scales, scaly hairs and silken hairs, becoming more dense and more whitish on lateral and posterior margins; collar yellowish-white; pleura densely covered with long white and yellowish-white hairs and scaly hairs; scutellum predominantly brown, black only at the basal margin and the middle, covered with long yellowish-white scales and silken hairs; all thoracic bristles yellowish-white; wings milky hyaline with faint costal infuscation, contact of fourth posterior cell (cua1) with discal cell (dm) approximately as long as basal vein of former or slightly longer, bristles of costal comb black, base of costal vein covered with white scales; halters yellowish-brown with knops yellowish-white; legs brownish with all tarsi, femora and tibia of mid and hind legs dark brown to black, femora and tibia covered with whitish scales become grayish on the apical half of mid and hind tibia, fore claws reduced. Abdomen. Tergites 1–3 black in ground colour with narrow yellowish-brown posterior margins, sides of tergite 2 reddish-brown, tergites 4–7 dark brownish-black with the narrow posterior margins yellowish; all tergites covered with silken white hairs and long white scaly hairs especially on sides and posterior margins; gonocoxa ( Fig. 11 View FIGURES 1–11 ) with a developed crest bearing stiff spine-like hairs, epiphallus ( Figs. 8–10 View FIGURES 1–11 ) relatively large, more than twice as long as the aedeagus, with a broad apex, aedeagus broad at base, thin and curved ventrally at apical part.

Female (paratype).
