Type material. Holotype. 3, TURKMENISTAN, Central Kopet-Dag Mts., Big Bakhcha River, 38°09’13,9’’ N 57°36’16,6’’E, 780 m a.s.l., light trap, 05.iv.2011 (A. Pototski leg.) [IZBE, micropinned]. Description. Male. Body length 3.00 mm (n=1).
Head black with numerous pale setae. Three ocelli, with laterals separated from eye margins by a distance less than their own diameter. Clypeus dark brown, with pale setae. Mouthparts brown. Palpus light brown, with two apical segments yellow. Scape and pedicel blackish brown, flagellomeres brown with short pale setae. Flagellomeres cylindrical, median flagellomeres about 2.3 times as long as broad, apical flagellomere elongated conical, 4.2 times as long as broad at base.
All parts of thorax black with yellowish white bristles and setae. Mesonotum shining. Scutellum with numerous setae, including marginal bristles not arranged in distinct pairs. Antepronotum and proepisternum with bristles and setae. Upper part of antepronotum with two strong bristle, one of them crossing the neck. Laterotergite and other pleural parts bare. Halteres yellow.
Legs. Forecoxa basally infuscated; midcoxa brown in basal fifth; hind coxa brown in basal third. Femora yellow, fore- and midfemur ventrally brown. All trochanters brownish. Tibiae yellow, foretibia apically thickened. Mid- and hind tibiae with two apicoventral spinules between spurs. Tarsal segments seem brownish because of dense setae. Midtibia with 6 a, 5 d, 8 pv and 3 p. Hind tibia with 14 a, 13 d, 4 av. Ratio of femur to tibia for fore-, mid- and hind legs: 1.6; 1.09; 0.82. Ratio of tibia to basitarsus for fore-, mid- and hind legs: 1.05; 1.48; 1.82.
Wings hyaline, length 3.51 mm. Radial veins and apical half of r-m brown, other veins paler and M-stem very faint. Sc, R4, bM-Cu, M-stem, basal third of cu-stem and basal third of A1 asetose; C, R1, R5 and r-m setose on both surface; M1, M2, apical two third of cu-stem, CuA1, CuA2 and apical two third of A1 setose on dorsal surfaces. Costa reaches 0.34 from R5 to M1. Sc distinctly ends in R, before the level of origin of m-stem. Anterior fork begins slightly before the level of R4. Posterior fork begins before anterior fork at level of middle of r-m. R1 2.9 times as long as r-m, which is 1.1 times as long as M-stem.
Abdomen brown with setae pale. First segment somewhat darker. Terminalia (Fig. 8) dark brown with gonostyli lighter. Ventroapical margin of gonocoxite with bifid megasetae bearing medial projection and wide lateral extensions. The gonostylus with three spines on ventromedial side. Tergite 9 widening apically; apical margin concave. Cercus with 12 combs of retinacula.
Female. Unknown.
Biology. Unknown.
Etymology. The name refers to the occurrence of the species in Turkmenistan.
Discussion. Docosia turkmenica is close to D. blagoderovi in sharing the general outline of male terminalia. See discussion under the latter for further details.
