Figs 1 , 2, 4–6

MATERIAL. Holotype – male, Kyrgyzstan: Teskey Ala-Too , River Chon-Kyzyl-Suu (ca. 42.3083 o N, 78.0804 o E), 2.V 1963, V. Sychevskaya ( ZISP). Holotype is pinned, in good condition, only the abdomen has been removed by me and the terminalia dissected; these are, and additionally right mid leg, in a microvial of glycerine pinned with the specimen .

DESCRIPTION. MALE. Head yellow. Frontal vitta matt; fronto-orbital plate grey dusted. Gena approximatelly 1/2 as high as eye. 2 orbital, 1 ocellar, 1 postocellar, 1 inner vertical, 1 outer vertical; postgena with 2 distinct setae. Antenna yellow ( Fig. 4 ). Postpedicel long-oval, approximately 1.3 as long as wide. Arista micropubescent ( Fig. 4 ). Palpus yellow completely.

Thorax yellow. Acrostichals absent, dorsocentrals 0+2, intra-alars absent, supra-alars 1+1, postpronotals 1, notopleurals 2, postalars 2. Proepisternum with long seta near lower margin. Katepisternum covered with rare black hairs, with 3 setae in posterodorsal corner. Anepimeron bare. Scutellum with a pair of basal scutellar and a pair of apical setae.

Legs yellow, only all tarsi blackish. Fore femur with 3–4 distinct dorsal setae in apical half. Fore tibia with preapical setae ventrally in

dorsal seta. Mid femur with 2 rows of short black apical third ( Fig. 2 ). Mid tibia with 1 distinct posterior seta at middle, 1 preapical dorsal seta, and a ring of apical setae. Hind femur in apical third with 2 rows of short black setae ventrally (as in mid femur), also with 2–3 posterodorsal setae in apical third. Hind tibia with 1 preapical dorsal seta, and a ring of apical setae.

11

Wing slightly tinged with pale brown, lacking dark markings, entirely covered with microtrichia ( Fig. 1 ). Veins pale brown. Vein R 1 setulose on apical third of dorsal surface.

Abdomen. Tergites 1–4 black, tergites 5–7, all sternites and postabdominal structures pale brown; tergites 1–5 covered with short black setulae and syntergite 1+2 with 2–3 long distinct setae on lateral sides; sternites 2–4 oval and sternite 5 trapezoidal. Postabdomen: epandrium saddle-like in shape in posterior view; surstylus triangular ( Figs 5, 6 ); anterior epandrial process flat and broad at apex ( Fig. 6 ); pregonite with 4–5 setae ventrally; phallus long, covered with numerous hairs posteriorly ( Fig. 5 ).

Female unknown.

MEASUREMENTS. Length of body 7.0 mm, length of wing 7.3 mm.

DIAGNOSIS. The new species is clearly distinguished from other representatives of the genus Paradryomyza by mid femur with two rows of short black setae ventrally in apical third and by the micropubescent arista ( Fig. 4 ). All other species of Paradryomyza has mid femur without 2 rows of short black setae ventrally in apical third and pubescent arista ( Fig. 3 ).
