| Итог: | This paper describes one new species Empis
shamshevi sp. n. of the subgenus Xanthempis Bezzi, 1909
taken from the Caucasian region of Russia (Krasnodar
province). Diagnosis. Occiput is almost completely dark,
scutum almost entirely black, prescutellar deepening is
yellow, scutellum from the front is black while the edges
are yellow, postsutural supra-alar bristle is presented.
Male: epandrial lamella with long hair-like yellow setae,
cercus with a plunging neckline, phallus medium length,
relatively thick, arcuately curved, with a long coracoid apex.
The changes of key to the Caucasian Xanthempis species
[Shamshev, Kustov, 2008] are given. Empis shamshevi sp. n.
is most similar to Е. testacea Fabricius, 1805 and E. adriani
Chvála, 1996 but it differs from them by almost entirely
fused black vittae on the mesonotum, which are slightly
separated on its posterior part, and also by the shape of
sclerites of male terminalia. In male terminalia the new
species resembles Е. zinovjevae Shamshev, 1998, however,
this species has single median vitta on the scutum. |
