minute dorsal setulae. 6th sternum simple, shortly setulose. 7th sternum with 4 longer setae besides a number of short setulae and somewhat posteromedial ly extended. 8th sternum characteristic in having very projecting posterior corners. 9th sternum very complex but membraneous anteriorly; ventrally shortly densely setulose and divided into two sclerites. Spermathecae (Fig. 14) with some tubercles on proximal part of body and the duct (sclerotized part) shorter than in L. parafinalis or L. finalis but longer than in L. alpina. Cerci fused with 9th tergum and much smaller than in L. alpina; they are rather short haired (see Fig. 12). Distribution — Known only from type specimens from Mongolia (Central and Bulgan aimaks, PAPP 1973). Discussion — This species belongs to the L. finalis-subgrouv constituted by species with similarly formed aedeagal complex and characteristically haired hind part of telomere. Besides L. equispina, this subgroup includes also L. alpina ROHÁCEK, L. parafinalis L. PAPP, L. finalis (COLL.), L. spinitarsata L. PAPP and L. dyscola sp. n. In the form of telomere (particularly as regards the posterior lobe of its fore part), male 5th sternum and wing venation L. equispina most resembles L. alpina ROHÁCEK, 1982 but this species has much shorter anterior projection of the fore part of telomere, dorsally fine haired distiphallus, different postgonite, simple female 7th sternum, 8th sternum with less projecting posterior corners and much better differentiated cerci (fused with 9th tergum in L. equispina).

Z. KASZAB, 1964. All types in HNHM (examined). Description — d. Total body length 1.78-2.26 mm; general colour brownish black, dark greyish brown pollinose, subshiny. — Head brownish black. Frons almost black, only anteriorly brown. Interfrontalia and orbits silvery grey pollinose and somewhat glittering, rest of frons dull. Cephalic bristles as in L. finalis, robust. Postverticals thin but well developed and crossed. 3 strong interfrontals becoming longer anteriorad and 1 small in front of them ; 2 additional microsetae situated lateral to the latter small interfrontal. 4-6 small additional setulae inside and below orbital bristles. Frontal lunule brown but facial cavity blackish and somewhat shiny. Gena blackish brown and dull; genal bristle comparatively strong. Eye diameter about 3.7 times as long as the smallest genal width. Antennae blackish, 3rd segment dark brown. Arista about 3.3 times as long as antenna, short haired. Thorax brownish black, mesonotum subshiny, pleurae heavily greyish brown dusted and dull. 2 humeral bristles and 1 microseta on humeral callus. 5(2+3) dorsocentrals becoming shorter anteriorad. 9 rows of acrostichal microsetae between dorsocentrals in front of the suture. 2 (1 +1) medial pairs of acrostichals enlarged but less than in L. fontinalis; also prescutellar medial acrostichal pair somewhat enlarged. Scutellum rounded triangular, large, with 4 pairs of scutellar bristles. 2 sternopleurals, the posterior very robust, its tip reaching the upper margin of mesopleuron. — Legs robust (femora in particular) dark to blackish brown but trochanters, knees and tarsi paler brown. Chaetotaxy of mid tibia (higs 21, 22) distinguished by very long and robust bristles. The most characteristic is an unusally long dorsal seta above the distal proximal long bristle and very long posteroapical bristles. Mid basitarsus with strong ventral bristle. Ratio t 2 : mt s = 1.93-2.06. — Wing (Fig. 40) with pale brownish membrane, veins brown. C not overpassing R i+5 . First costal
