Timia (Empyelocera) flaveola Galinskaya sp. nov.

( Figs 9–10 )

Type material. Holotype Ƥ: Turkmenistan: “Репетек, личинки в корнях Convolvulus. Лет-конец июня, собр. Каплин, 27.IV.1980 ” [Repetek, larvae on the roots of Convolvulus ( Convolvulaceae ), hatching in the late June, 27 Apr. 1980 Kaplin leg.] ( ZISP). Paratypes: 5 Ƥ, label as in holotype; 1 Ƥ, Turkmenistan: “Репетек, Туркм. бел., саксаульник близ усадьбы, Стальмакова, 21.VI.1947 ” [Repetek, (bel., saxaul near the estate), 21 June 1947 Stal’makova leg.] ( ZISP).

Diagnosis. The new species is similar to T. (E.) orientalis , differing by the mesonotum silvery white microtrichose, without rows of confluent shining spots around setae. Posteroapical extension of cell bcu 1.5 times as long as cell at its middle (in T. (E.) orientalis , with posteroapical extension of cell bcu 0.4 times as long as cell at its middle). Cercal unit with three pairs of long basal setulae ( T. (E.) orientalis with two pairs of setulae). Aculeus with four rows of short setae at each side ( T. (E.) orientalis with two rows of setae).

Description of the holotype. Female: Head. Frons yellow, evenly covered with short and thin black setulae. Frons with weak microtrichosity close to eyes. Ocellar triangle shining black. Lateral parts of vertex entirely yellow without dark markings. Occiput yellow, covered with short and thin black setulae. Median occipital sclerite pale yellow, with silver-white microtrichosity close to vertex; lateral occipital sclerites pale yellow, with silverwhite microtrichosity close to eye margin. Postgena yellow. Parafacialium narrow, 0.5 times as wide as antennal grooves, or the same width as the flagellomere 1. Gena yellow, shining, 0.3 times as high as eye. Eye 1.3 times as high as wide. Lunula yellow. Face yellow, without darkened band along the lower edge. Clypeus yellow. Scape and pedicel yellow. Flagellomere 1 yellow, matted, with a dark spot on the dorsal side, distally. Arista yellow. Antennal grooves yellow, with thin silver-white microtrichosity. Proboscis yellow. Palpus yellow. Setae. 8 small orb (first orbital seta a little longer than the other ones), 1 divergent oc, 1 divergent poc, 1 long divergent m vt, 10 divergent pocl, 1 short pa vt and 1 long convergent i vt. 12 gn, 10 pgn setulae, 1 long gn seta. 2 groups of spc setae over occipital foramen.

Thorax. Yellow, with brown lateral spots (mainly on presutural area of scutum) and median strips. Mesonotum with solid silver-white microtrichosity, without rows of confluent shining spots around base of setae. Postpronotum with silver-white microtrichosity. Scutellum subshining pale yellow, faintly sculptured, with short black setulae over its upper surface. Mediotergite yellow, with brown spot at middle. Pleura yellow, with slight microtrichosity on the upper edge of anepisternum. Katepisternum with brown spot in ventral portion. Setae. 1 pprn, 2 npl, 1 spal, 1 prsc dc, 1 pal, 1 ial seta; 2 pairs of sctl; anepm setae absent; 1 anepst, 1 kepst seta; also anepisternum and katepisternum covered with short black setulae.

Legs. Entirely yellow, last tarsomere darkened to pale brown.

Wings. Hyaline. Cell r4+5 open, but apices of veins R4+5 and M almost contact. Posteroapical extension of cell bcu 1.5 times as long as width of the cell at its middle. Halter yellow.

Abdomen subshining, evenly short and thin black setulose. All tergites laterally yellow, brown at middle. Sternites yellow.

Female terminalia: Aculeus 3.5 times as long as wide at its middle, with four rows of short setae at each side. Cercal unit elongate oval, with 1 pair of long basal setulae, 1 pair long and 3 pair short apical setulae. 3 spherical spermathecae with smoothed cellular surface and inverted necks; two left with T-shape bifurcated common duct.

Body length 3.5–5.0 mm. Wing length 2.7–4.0 mm.

Male. Unknown.

Remarks. Variability was observed in number of setae among examined specimens: 8–14 small orb, 10–12 divergent pocl, 12–16 gn, 10–12 long pgn setae; microtrichosity on anepisternum sometimes almost indistinguishable.

Etymology. This name is derived from the Latin world “flava”, yellow. Distribution. Turkmenistan.
