— Hind part of telomere with long setiform hairs distributed along its whole length (i. e. also in distal part — Figs 8, 24) 8 7 (6) Anterior projection of fore part of telomere more slender, posterior lobe of this fore part longer, robust, rounded and bearing long bristles on ventral margin, terminated by a long and robust posterior bristle (ROHÁCEK 1982a: Figs 21, 22); male 5th sternum with longer haired posteromedial membraneous area (ROHÁCEK 1982a: Fig. 18) L. fontinalis (FALLÉN) — Anterior projection of fore part of telomere more robust, posterior lobe of this fore part very short and wide, characteristically shaped and bearing short setae on ventral margin and a very thick but short, spine-like posterior bristle arising on darkly pigmented projection (Fig. 2); male 5th sternum with shorter finely haired posteromedial membraneous area (Fig. 6) L. vomerata sp. n. 8 (6) Mid basitarsus with a long and stout ventral bristle (Fig. 27). Fore part of telomere with robust and short anterior finely pubescent projection armed by strongly sclerotized anterior thorn-like corner; posterior lobe of this fore part also unusually bulky and characteristically shaped ventrally; hind part of telomere short and stout (Fig. 24) L. spinitarsata L. PAPP — Mid basitarsus with weaker ventral bristle (Fig. 11). Fore part of telomere with long and slender anterior finely pubescent projection without thorn-like corner; posterior lobe of this fore part anteriorly short, posteriorly rounded but of more subtle construction; hind part of telomere longer and slender (Fig. 8) L. equispina L. PAPP 9 (5) 7th tergum distinctly shorter; posterior margin of 7th sternum simple; 8th sternum with posterior corners less projected; spermathecae without thorn-like tubercles in proximal part of body (ROHÁCEK 1982a: Figs 42—45) L. fontinalis (FALLÉN) — 7th tergum distinctly longer (Fig. 12); 7th sternum posteromedially slightly, but distinctly, extended; 8th sternum with posterior corners more projected (Fig. 13); spermathecal body with thorn-like tubercles (Fig. 14) L. equispina L. PAPP Leptocera (Leptocera) fontinalis (FALLEN, 1826) For detailed redescription, figures of the male genitalia and female terminalia, synonymies, biology and distribution see ROHÁCEK (1982a). L. fontinalis has been recorded from the East Palaearctic only twice — by PETROVA (1968) from Far East and by L. PAPP (1974) from Mongolia. Unfortunately we were unable to examine these specimens to check their identification. We have not excluded the possibility that they (or some of them) might be L. vomerata sp. n. Although East Palaearctic records of L. fontinalis have not been confirmed, we have included this species in the key because its occurrence in this area is probable. Leptocera (Leptocera) vomerata sp. n. Q* (Figs. 1-6, 38) Type material — Holotype o* : USSR, Amurskaya obi., g. Zeya, 3 IX 1981, A. SHATALKIN leg. Deposited in MGU. Description — d\ Total body length 2.30 mm; general colour brownish black, brown Pollinose but subshiny. — F r o n s brown anteriorly to blackish posteriorly, dull. Orbits and interfrontalia somewhat silvery grey pollinose; narrow frontal triangle somewhat shiny. Cephalic chaetotaxy robust, also postverticals well developed, crossed. 3 interfrontals becoming longer anteriorad and 1 small in front of the longest one; lateral to the small interfrontal an additional weak setula. About 6 small additional setulae inside and below orbitals but only 2-3 uppermost longer. Frontal
