only 3 pairs of them longer than other microsetae. Scutellum large, rounded triangular, with 4 pairs of scutellars as usual. 2 sternopleurals (large posterior, short anterior) and 1 microseta between them but arising more ventrally. — Legs brown, trochanters, knees and tarsi pale brown. Chaetotaxy of mid tibia (Figs 10, 11); posteroapical bristles short, subequal in length. Ratio t., : mt., — 1.88, thus mt

2 (mid basitarsus) rather long and slender. — Wing (Fig. 39) with brownish membrane; veins brown. C not extended beyond R

i+S- First costal sector sparsely and long haired. R.,

i+5 slightly curved up to C. Discal cell of medium length, with rather long processes of M

1+2 and M

3+i beyond t

p

, the former continued by colourless venal fold reaching wing margin. Alula rather large but tapered apically. Wing measurements: length 1.79 mm, width 0.77 mm. C-index = 1.62, f

: 'p — 2.62. Haltères yellow with pale brownish knob. Abdomen brownish black, rather shiny. Terga sparsely haired except for the long bristles in posterior corners of 4th and 5th tergum. Syntergum 1 —2 basally paler pigmented. Sterna more densely, short haired. 5th sternum extremely like that of L. alpina, having similar chaetotaxy as well as extent of membraneous, finely pilose, posteromedial area. Genitalia rather narrow in caudal view, see Fig. 7. Periandrium shortly setose except for the long caudal bristle. Hypandrium rather long, Y-shaped. Intraperiandrial sclerite well developed and subanal plate absent. Pseudocerci rather long haired and with a long, slender ventral projection. Telomere (Fig. 8) resembling that of L. alpina but the anterior finely pubescent projection much longer and posterior long bristle and other short setulae differently positioned on the posterior lobe of the fore part of telomere. Hind part of telomere long and slender, with more posterior setiform hairs than in L. alpina and the anterior bristles situated closely each other and 2 thicker bristles on apex are Figs 7-11. Leptocera (s. str.) equispina L. PAPP (holotype): 7 = male genitalia caudally (aedeagal complex omitted); 8 = telomere laterally ; 9 = aedeagal complex laterally (right postgonite omitted); 10 = left mid tibia dorsally, 11 = apex of mid tibia and mid basitarsus posteriorly. — Scales: Fig. 7 = 0.1 mm, Figs 8, 9 = 0.05 mm, Figs 10, 11 = 0.2 mm
