diagnosis
Diagnosis. Males of Sylvenomyia fennica differ from males of Sylvenomyia spinigera, which is a closely similar species, as follows. The hair-shaped translucent sensilla on the antennal flagellum are shorter and fewer. CuA 1 is never traceable. The ventral emargination of the gonocoxites is deep-V-shaped (Fig. 2 B). The gonostylus is more elongate and less curved; the apical claw is more slender (Fig. 2 B). The ejaculatory apodeme bears apically a very large membranous extension (Fig. 2 D). The ventrolateral tegmen margins have a scaly surface that in some specimens is more distinctive than in others (Fig. 2 D).
distribution
Distribution and phenology. Sylvenomyia fennica is apparently widespread throughout Finland and, according to our records, penetrates northwards to 67 ° N. Adults were collected exclusively in stands of oldgrowth taiga between late June and late August. Most of the specimens were caught by sweepnet, a few others by Malaise trap. Larvae are unknown.
