New species of genus Eumerus Meigen, 1822 (Diptera, Syrphidae) from Eastern Kazakhstan

Abstract

In 2021, in the course of work on the study of the entomofauna of the Tarbagatai State National Natural Park in the southern spur of the Tarbagatai Ridge in the Karabas Mountains, a male of hoverfly fly (Syrphidae) of the genus Eumerus was found in the spider web, which is described in this paper as a new species E. kolovi sp. n. The male of the described species is close to the male of E. longitarsis Peck, 1979, from which it differs in the location of the eyes and ocelli, the shape of the antennae, and the presence of longitudinal plaque stripes on the mesonotum.
