Type locality. " Insel Rhodus und die Gegend von Mermeriza" (Greece).

Distribution. Europe except northern part, southwestern Asia, Mediterranean.

Adult activity in Israel: End of March to beginning of July.

Diagnosis. This species differs from its congeners in the following combination of characters: hyaline wing, slightly widened hindfemur, and the structure of the glans.

Comments. U. wadicola Steyskal is similar but the hindfemur of the male is considerably wider than in U. albidipennis . This species and U. erythrophthalma belong to the erythrophthalma species group (Hennig, 1940). They can be distinguished only by the structure of the glans (Kameneva, 2008).
