A new hoverflies species Eumerus longipilosus sp. n. is described from Kyrgyzstan. Due to the presence of longitudinal and transverse grooves on the postpedicel, a broad body, and the absence of anterior lobe on the epandrium, the new species should be classified as a member of the Eumerus tricolor group. It differs from all other species in this group by the presence of long black pilis on face and on mesofemur, the characteristic structure of the epandrium, and several other minor differences.
