Leptocera (Opacifrons) elbergi sp. n. (Figs. 4-5) Head comparatively big, 2 ors, vie, vti, oc, occe, occi bristle pairs well developed. 4 pairs of short if, vibrissae and upcurving genal bristle strong. Lower part of facial plate ochreous yellow with some greyish pollen. Smallest width of genae only 1/6 of longitudinal axis of eyes. Antennae as in coxata. — Legs dark brown, mid tibia with anterodorsal bristles at 1/3 (strong), 11/15 (weak), at 5/6 (strong), posterodorsal only at 7/10 of tibia. Mid tibia of females without bristles ventrally, ventral side of mid tibia of males with a complete row of short thick bristles (longer only in apical fourth), mid metatarsus of both sexes ventrally with a strong subbasal bristle.—

T h o r a c i c chaetotaxy : 1 h, 2 np,\ prst, 2 sa, 1 pa, 1 prsc, 2 dc, 2 sc, 1 st pair of bristles. — Wings light brownish, veins brown, m^ of costa with 7-8 pairs of moderately long bristles, vein r

i+5 almost straight in basal part, anyway in apical part slightly upcurving, discal cell angulate, vein appendage short and faint. c

x = 0.78, ía-Zp/íp = 1.65. — Male epandrium as in coxata STENH., its surstylus otherwise shaped and its armature are different from that of coxata (Fig. 6, cf. ROHÁÖEK 1975: Fig. 5), subanal plate has a pair of very long processes (Fig. 5), this process has a strong apical spiniform bristle, gonites (postgonite) shorter than that of coxata. Male 5th sternite (Fig. 4) has a mid apical process, end of this process is truncate, 5th sternite almost without bristles on its disc. -— Female cerci with two short spines each, similar to those of coxata, supra-anal plate in two parts. Body length of holotype male: 1.45 mm, paratypes: 1.49-1.78 mm; wing-length: holotype male: 1.40 mm, paratypes: 1.41-1.84 mm, width: holotype: 0.65 mm, paratypes: 0.67-0.79 mm. Holotype male: Habarovsk krai, Pivan, 16. 8. 73, ELBERG — „ojokallas". — Paratypes : 1 9 '• data same as for holotype; 2 çf: Habarovsk krai, P. Osipenko, 29. 7. 73, ELBERG — ,,tarnasoo". The holotype and two paratypes are deposited in the Zoológia ja Botanika Instituut Tartu, one male paratype in the Hungarian Natural History Museum, Budapest. Leptocera (Opacifrons) elbergi sp. n. is related to L. (O.) coxata STENH. and it differs from it by its genitalia only. The male 5th sternite has a big, strong mediocaudal apex, contrarily to coxata, terminal process of subanal plate is very long (very short in coxata), the shape and armature of its surstylus are also different; the female supra-anal plate consists of two parts.
