E706CB455960FFC5FF4C07D7FC37FC13.taxon	description	Description. Abdomen and thorax light brown. Wings, head, antennae and palpi brownish yellow. Head with long yellow hairs. Wings brown, heavily covered with long dark hairs, with 2 pairs of tufts of modified hairs and scales in the basal part and along the costal edge of the wing. Antennae shorter than forewings, with 25 segments. Venation strongly reduced, only forks 2 and 3 present in forewings. Wings very narrow with an elongated and rounded apex. Mesoscutellum without transverse suture. Process of sternite VII very long and thin, with clavate extension at apex in lateral view, does not reach segment IX. Lateral processes of sternite V associated with pheromone glands absent. Spur formula: 0.3.4. Male genitalia. The inferior appendages are formed by two straight branches. Ventral branch has triangular shape with sharp apex. The dorsal branch elongate with expanded rounded apex. The ventral branch shorter than the dorsal one. The preanal appendages rounded. Aedeagus long and slender, with a widened and obliquely cut apex in lateral view. Measurements. Holotype: body length 2.6 mm; forewing length 2.8 mm. Paratype: body length 2.0 mm; forewing length 2.1 mm.	en	MELNITSKY, STANISLAV I., IVANOV, VLADIMIR D., PERKOVSKY, EVGENY E.

E706CB455960FFC5FF4C07D7FC37FC13.taxon	discussion	Remarks. The new species is similar to Electrotrichia subtilis Ulmer, 1912 from Baltic amber. Electrotrichia rasnitsyni sp. nov. differs by the shape of the inferior appendages: both branches straight, ventral branches triangular with a wide basal part, dorsal branches lobeshaped with expanded apex, not uniformly finger-like, curved inwards, and slender as in E. subtilis. The sternal process of the segment VII in the new species is shorter, does not reach the segment IX.	en	MELNITSKY, STANISLAV I., IVANOV, VLADIMIR D., PERKOVSKY, EVGENY E.
