Type locality.

Italy (Calabria).

Male.

Body length 2.25 mm; forewing length 6.5 mm, hindwing length 5.5-6.5 mm.

Head yellowish, vertex caudally darker. Antennae pale yellow, scapus and pedicellus brownish. Mouthparts yellow.

Prothorax yellow; meso- and metathorax darker. Legs yellow. Wings hyaline, membrane uncoloured; forewing veins yellowish; hindwing veins pale yellow, paler than in forewing.

Abdomen dorsally brown with yellow pattern, ventrally yellowish with only a few brownish spots. Gonocoxites 9 as huge plates, gonostyli 9 digitiform, gonapophyses 9 processus-like; ectoproct broadly rounded. Complex of gonocoxites + gonostyli + gonapophyses 10 amalgamated with sternite 9, forming a pseudoapex of the latter and framing it laterally, terminally deeply forked. Gonocoxites 11 fused into a bow-like bridge.

Female.

Body length 2.4 mm; forewing length 7.2-8.2 mm, hindwing length 7.6-7.8 mm.

Fused gonocoxites 8 forming a broad trapezoid sclerite; fused gonapophyses 8 triangular; gonocoxites 9 club-shaped, without distinct gonostyli; bursa copulatrix comprising a sclerotized structure.

Specimens examined and records published.

Biology and ecology.

Adults have been taken from May–July; most specimens were collected in May. The known vertical distribution is 354-1350 m. The larva is known and has been described ( Malicky 1984), the temperature of inhabited brooks measured varied from 7.9-23.8°C.
