Dolichogenidea sp.

Fig. 12 (A–D)

Material examined: 1♂, Kharga Oasis (New Valley) [25°31’34.0”N 30°37’19.9”E], May, 2022, white pan trap in V. faba intercropped with B. napus .

Diagnosis. Head (including antenna), mesosoma, metasomal T 1 black; laterotergite of T 1 and following tergites brownish yellow with thin whitish posterior margins; palpi brownish with palpomeres whitish at apices; tegula partly yellow; legs dark brown, with paler tarsi; fore wing hyaline giving off coloured reflections, all veins waxy white. Antenna slightly but distinctly longer than body; mesoscutum and scutellum densely finely punctate throughout; scuto-scutellar sulcus linear and smooth (not crenulate); propodeum nearly smooth; fore wing with venation proximal to areolet waxy; metacarp distinctly shorter than pterostigma length (0.74×); T 1 and T 2 finely, superficially rugose; rest of tergites smooth; T 2 very short, distinctly shorter than T 3; fore wing with pterostigma large, robust, 2.1× as long as wide, vein r relatively long, issuing from middle of pterostigma and forming a distinct obtuse angle with vein 3-SR; second radio-medial vein absent; male genitalia short, barely exserted from metasomal tip.

Comments. Although this is a male specimen, it agrees to some extent with D. appellator in Papp’s key (1978: 276, couplet 48). However, in Papp’s key, the pterostigma is entirely pale yellow (entirely waxy in our specimen), so, we have identified it as Dolichogenidea sp. until females become available.
