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.

Holotype ♂ Eumerus maculipennis Becker , 1921: "Transkaspien / 57442", " maculipennis / Beck / det Becker", “Holotypus” [red label], "Zool. Mus. / Berlin " , " Holotype ♂ / Eumerus maculipennis / Becker, 1921 / det. J. van Steenis, 2016, ( ZMHU) .

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.
