Eumerus binominatus Herve-Bazin, 1923 Fig. 1A, B

Notes.

This species was originally described by Becker (1921) as E. maculipennis from Transcaspia (south part of Kazakhstan). Hervé-Bazin (1923) revealed this name as a junior homonym of Eumerus maculipennis Bezzi, 1915 from Nigeria and named Becker’s species E. binominatus . The holotype is held in ZMHU and has been examined.

Material examined.

Diagnosis.

Male eyes separated by width of ocellus. Face black, covered in whitish pilosity with few black pilosities above antennae (Fig. 2A). Antenna brown-red and slightly higher than long (Fig. 2B). Wing with a dark spot (Fig. 1B). Metafemur with row of about 7 rather long black setae, which are about 1/2 as long as width of metafemur. Abdomen partly red (Fig. 1A).

This species is similar to E. tadzhikorum but differentiated by the shape and color of the basoflagellomere.
