T2 baso-laterally with transversal groove. Median emargination on posterior border of S6 as in Fig. 4 . S8 (hypopygium) with median longitudinal carina, slightly divergent apically, basally with distinct emargination and sharp differences between sclerotized and unsclerotized parts (Figs 8, 9). Genitalia as in Fig. 29 .

Head, scape ventrally, propleuron, fore coxa with dense long erect brownish setae. Mesopleuron and propodeum laterally and posteriorly with very long erect brownish setae. Pronotum, mesonotal scutum and T1 laterally with scattered long erect setae. Scutellum, fore and mid femur, mid and hind coxa, S1, S2 with sparse erect setae. T2–T6 and S3–S6 without setae. Lower part of face with silver pubescence with brownish tint. Body with iridescent brown pubescence; T1–T5 apically with denser brown pubescence. Body regularly micropunctate. Body and legs black, outer eye orbit near vertex with small pale patch, T1 and T2 laterally with indistinct ferruginous-red patches.

Type material. Lectotype, designated here, 3 "Jagnob. Kol. // к. Ф. Моравица [cyrillic] // Pompilus colensis 3. F. Moraw. // Lectotypus Pompilus sogdianus F. Morawitz, 1893 3 design.

Tajikistan. 1 3, Gissarskii Mountain Ridge, Anzob Pass, 3600 m, 31.VII.1937 (Pavlovskii) [ ZIN].

Distribution. Tajikistan.

Remarks. During our study of the Morawitz collection in the Zoological Institute, St. Petersburg, we found a male and a female of Pompilus colensis from "Jagnob. Kol" [ Tajikistan] ( Figs 1, 2 ). No species under this name has been described by Morawitz and no types of Pompilus sogdianus Morawitz has been known before that. The description of P. sogdianus includes many characters that totally agree with the specimens of P. c o l e n s i s. This is a case where Morawitz likely mislabeled the specimens. The name colensis originates from Kol (Kul), the river in the Jagnob basin, while sogdianus refers to the ancient people who lived in these places of Tajikistan. The male and female of Pompilus sogdianus sensu Morawitz 1893 remarkably differ by wing venation (Figs 40, 41 vs. 42, 43, 66) and definitely belong to different species. We conserved the name sogdianus for male (lectotype). The female (paralectotype) belongs to Psammochares binaevus Haupt 1930 .
