Summary: | Izleiina mirifica , new species Figures 52–54, Plate 5F DIAGNOSIS: Apical palpomere short. Tibiae without bristles. Gonostyli conical, curved inward. DESCRIPTION: Body length = 1.44 mm, wing length = 1.23 mm. Head: Ocelli three, distance from eye margin equal to two ocellus diameters; distance between each other equal to one diameter. Flagellum 14segmented, flagellomeres cylindrical, lengths about equal to widths, covered by setulae no longer than onehalf flagellomere width. Palpi 4segmented, three basal segments bacilliform, apical one short and rounded. Occiput, frons, face, and clypeus with short setulae. Thorax: Prescutum and anterior parapsidal suture distinct. Antepronotum with 6 setae, proepisternum with two. Scutum arched. Scutellar setae in rows. Scutellum with two pairs of long setae. Cavity on anterior edge of katepisternum shallow. Laterotergites and mediotergite bare. Wing: Sc meets C just beyond level of base of M3. C ends far beyond apex of R 5. R 1, R 5, and rm with setae. R 1 length 2Χ that of rm. R 5 straight. Length of crossvein rm 0.5Χ length of section M3. M3 weak, can be seen only by absence of microtrichia on wing membrane. M and CuA fork base proximal to the base of rm. M 3+4 interrupted at base, not reaching wing margin. Legs: Fore coxae with anterior setae, mid coxae with lateroapical ones. Tibiae without bristles. Genitalia: Gonocoxites massive, fused. Gonostyli hornlike and slightly curved, with long setae, colored lighter than gonocoxites. 3+4 MATERIAL: Holotype PIN 3130 /187, male. Russia: Taimyr Peninsula, Yantardakh, coll. 1970. ETYMOLOGY: The species epithet is a Latin word mirificus meaning ‘‘amazing’’ in reference to unusual combination of characters. The name is feminine.
