Type material.

Holotype male: Uzbekistan: "70 км СЗ Газли, пески Кызыл Кум, Зайцев, 27.V.1965" [70 km NW Gazli, sands of Kyzyl Kum, Zaitzev leg. 27.V.1965] (ZISP).

Paratype: Uzbekistan: 1 male, same data as holotype (ZISP).

Diagnosis.

Timia lazebnayae sp. n., Timia shatalkini sp. n. and Timia gobica differ from all other Timia species by cell r4+5 completely closed, forming petiole at wing tip and by parafacialium narrow, almost 0.3 times as narrow as first flagellomere. Timia lazebnayae sp. n. differing from Timia shatalkini sp. n. and Timia gobica by first flagellomere entirely yellow. Timia lazebnayae sp. n. is characterised by body yellow; cell r4+5 apically completely closed, forming petiole at wing tip; parafacialium less than half as wide as flagellomere 1, and narrower than antennal groove; flagellomere 1 entirely orange.

Description.

Male: Head. Frons pale yellow, evenly covered with short and thin brown setulae. Frons with band of weak microtrichosity along eye margin. Ocellar triangle shining black. Lateral part of vertex entirely yellow without dark markings. Occiput pale yellow, covered with short and thin black setulae. Medial occipital sclerite yellow; lateral occipital sclerite yellow, with silver-white microtrichosity. Gena yellow, 0.25 times as low as eye. Postgena yellow. Parafacialium yellow, 0.3 times as narrow as antennal grooves, 0.5 times as narrow as flagellomere 1. Eye as high as wide. Lunula pale yellow. Face yellow, without darkened band along the ventral edge. Clypeus yellow. Scape and pedicel yellow. Flagellomere 1 completely yellow, matted, roundish. Arista yellow. Antennal groove yellow, with thin silver-white microtrichosity. Proboscis yellow, slightly darkened distally. Palpus yellow.

Thorax. Yellow, with pale brown lateral spots (mainly on presutural area of scutum) and with medial stripe. Mesonotum with silver-white microtrichosity, lateral spots and medial stripe. Postpronotum slightly microtrichose. Scutellum nearly shiny, yellow, with short black setulae ventrally. Mediotergite dark brown. Pleura yellow, slightly microtrichose on dorsal edge of anepisternum. Pleura covered with sparse short black setulae. Katepisternum with pale brown spot in ventral portion.

Setae. Two small orbital setae (dorsal seta little longer than ventral seta), one divergent ocellar seta, one divergent postocellar seta, one long divergent lateral vertical seta, five divergent postocular setae, one short paravertical seta, and one long convergent medial vertical seta. Three postgenal setulae, one long genal seta. Two groups of supracervical setae over occipital foramen. One postpronotal seta, two notopleural setae, one supra-alar seta, one prescutellar dorsocentral seta, one postalar seta, one intra-alar seta; two scutellar; anepimeral setae absent; one anepisternal seta, one katepisternal seta, anepisternum and katepisternum covered with short black setulae.

Legs. Entirely yellow.

Wings. Hyaline. Cell r4+5 completely closed, forming petiolate at wing apex. Posteroapical extension of cell bcu 0.2 times as short as width of the cell at its middle. Halter yellow.

Abdomen. Yellow, non-microtrichose.

Male genitalia. Surstylus with anteroventral lobe, curved proximally at right angle, bearing two spines at its medial margin; and with short posteromedial lobe covered with setulae ventrally. Cerci tapered at apex, separated by narrow slit, covered with long setulae.

Body length, 3.5-3.6 mm. Wing length, 3.1-3.2 mm.

Female: unknown.

Etymology.

The name is in dedication to a good friend V.S. Lazebnaya.

Distribution.
