This species was originally described by Becker (1921) as E. maculipennis from Transcaspia (south part of Kazakhstan ). Herve-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). Figure 1. Eumerus binominatus , male holotype of E. maculipennis A dorsal view B lateral view. Eumerus tadzhikorum , male, Kazachstan C dorsal view D lateral view. Scale bar: 1.0 mm. Figure 2. Eumerus binominatus , Male holotype of E. maculipennis A head, fronto-lateral view B antenna, lateral view. Eumerus tadzhikorum , male, Kazachstan C head lateral view D antenna lateral view. Scale bar: 1.0 mm. This species is similar to E. tadzhikorum but differentiated by the shape and color of the basoflagellomere.
