Synonymy is confirmed.

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 .
