| Sumario: | A new species Leptogaster rutulica sp. n.
from southwestern Dagestan is described with
comprehensive photographs of the external morphology
and details of the male genitalia. Differences from other
species of the genus Leptogaster Meigen, 1803, and
especially from the closely related species L. subtilis
Loew, 1847 are shown. The species is characterized by
the presence of very characteristic features, which are
not observed in other members of Leptogaster species
occurring in the Caucasus. The new species differs from
L. armeniaca Paramonov, 1930, L. calceata Engel, 1925,
L. cylindrica (De Geer, 1776) and L. pubicornis Loew, 1847
in the shape of the epandrium with a distinct spine medioposteriorly,
by the presence of numerous black hairs and
strong bristles at the tip of the epandrium, and the lateral
processes of gonostyli sharply curved and bent down. The
new species has two extensive apubescent areas on the
mesoscutum, reaching the middle of the mesonotum and
also clearly distinguished from Leptogaster subtilis by the
presence of the distinct spine medio-posteriorly on the
epandrium |
