Differential diagnosis
By structure of the male terminalia, D. anatolica sp. nov. resembles D. juxtamontana Chandler, 2004 and D. incolamontis Chandler, 2004. All species have a bifid gonostylus and posteroventral margin of gonocoxites with a prominent medial process surrounded by two small lobes bearing setae. These setae are apically ramified in D. anatolica sp. nov., but with an unknown structure in the other two species. Apically modified setae at the posteroventral margin of gonocoxites are frequent in CentralAsian species (cf. Kurina & Ševčík 2012) but they are also observable in other species, e.g., in the European D. pannonica Laštovka & Ševčík, 2006. Docosia anatolica sp. nov. has the ventral lobe of the gonostylus obtriangular, with spines at both posterior corners, while it is slender and furcated, with medial and apical spines in D. juxtamonta and irregularly crescent-shaped with two subapical spines in D. incolamontis.
Etymology
The species name refers to the type locality in Anatolia (Asia Minor).

Description
Male (n = 1)
MEASUREMENTS. Length of wing 4.2 mm.
HEAD. Blackish brown with numerous pale setae. Three ocelli, lateral ones almost touching compound eyes, separated from eye margins by less than half of their own diameter. Mouthparts light brownish. Palpus brownish yellow, basal segment and apical part of last palpomere darker. Scape, pedicel and all flagellomeres dark brown. Flagellomeres cylindrical, flagellomeres 1 and 2 about twice as long as broad, other flagellomeres (3 to 14) about three times as long as broad.
THORAX.All parts of thorax blackish brown, with light setae. Scutellum with numerous setae and several submarginal pale bristles about twice as long as scutellum. Antepronotum and proepisternum with pale bristles and short darker setae. Laterotergite and other pleural parts bare. Haltere pale yellow.
LEGS. All coxae yellow, with basal third darkened. Femora mostly yellow, fore and mid femur dark along ventral margin, more extensively in proximal third; similarly hind femur, which is brownish also around tip. Trochanters blackish brown. Fore tibia brownish yellow, apicomedially with simple semicircular tibial organ (anteroapical depressed area), without strong setae, only densely covered with fine setulae. Mid tibia darkened dorsally. Hind tibia mostly brownish yellow, with small black dot approximately in middle of dorsal surface.
WINGS. Hyaline, unmarked. Radial veins and r-m dark brown, other veins paler, basal parts of m faint, almost not traceable. Sc, Rs and basal third of cu-stem asetose, other veins setose. Costa reaches to about one third of distance between R 5 and M 1. Sc ends in R before level of beginning of m-stem. Posterior fork begins before anterior fork, approximately at level of basal third of r-m.
ABDOMEN. All dark brown.
TERMINALIA (Figs 2 A–E, 7A). Dark brown except lighter gonostyli and posterior margin of gonocoxites. Tergite 9 subrectangular, about 1.5 times as long as broad, slightly broadening posteriorly, posterior margin with medial incision. Posteroventral margin of gonocoxites with blunt lateral projections and prominent rounded process medioventrally, surrounded by two shorter processes bearing apically ramified thick setae. Gonostylus bifid. Ventral lobe of gonostylus obtriangular in ventral view, with dark tooth at both posterior corners. Dorsal lobe of gonostylus larger than ventral lobe, bent inwards and rounded apically, with large aggregation of setulae along ventral surface anteriorly, prominent subapical seta posteriorly and with about 10 setae posterolaterally. Cercus with 16 combs of retinacula.
Female
Unknown.
