description: Key to Caucasus species of Drymeia Meigen
1 Facial edge not or only a little projecting forward beyond the level of the profrons when the head is viewed in profile (Fig. 22). Scutellum on the lateral margins, below the level of the strong setae, with 5–10 setulae in 1–2 rows. ♂: prealar seta absent or short, shorter than 2nd notopleural seta (present in some D. vicana). ♀: hind tibia without a posteroventral apical seta..... 2
- Facial edge projecting forward far beyond the level of the profrons when the head is viewed in profile (Fig. 12). Scutellum bare on lateral margins, but with a row of setulae on the ventral surface in D. sororcula. ♂: prealar seta present and strong. ♀: hind tibia with a posteroventral apical seta..................................................................... 4
2 Anepimeron setulose. Katepimeron with a few short setulae. (♂ with the tip of the abdomen forming a “basket”, with numerous dense setae on the apical margin of tergite 5 and on subsequent tergites, enclosing the genital capsule; mid femur without posteroventral setae except for a group of fine curled setae at base, some longer than femoral depth; hind femur with a row of anteroventral setae in apical half but without posteroventrals except at base).................... D. caucasica (Schnabl)
- Anepimeron bare. Katepimeron bare...................................................................... 3
3 Eyes densely haired, less conspicuously so in female. ♂: fore leg with no posteroventral setulae at apex of tarsomere 1; mid femur with complete rows of fine anteroventral and posteroventral setae, the posteroventrals longer; hind femur with complete rows of anteroventral and posteroventral setae................................................. D. vicana (Harris)
- Eyes bare. ♂: fore tarsomere 1 with several long posteroventral setulae near apex; mid femur without posteroventral setae, and without anteroventrals except for some long, bent setae on basal quarter and some long anterior setae above them (Figs 4–5); hind femur with anteroventral setae in apical half but without posteroventrals..................... D. setibasis (Huckett)
4 Parafacial very broad, at middle almost twice as wide as width of postpedicel (Fig. 12). Face with a prominent snout between the base of the antennae. (3 postsutural dorsocentrals.) ♂: hind tibia with a posteroventral apical seta, but with no prolongation of the apex of the tibia to form a short spur (Fig. 13). (♂ with complete rows of anteroventral and posteroventral setae on mid femur and hind femur, these rows also complete but sparser in the ♀)............................ D. fratercula sp.nov.
- Parafacial narrower, at middle equal to width of postpedicel (Fig. 33). Face without a snout between the antennae. ♂: hind tibia without a posteroventral apical seta, but with a ventral spur-like prolongation of the apex of the tibia................... 5
5 4 postsutural dorsocentral setae. Scutellum bare on ventral surface.Anepimeron always bare. ♂: mid femur with the anteroventral setae restricted to a group of 5–6 setae in apical fifth, and with posteroventral setae in basal two-thirds (Fig. 5); hind femur with a complete row of anteroventrals, but with no posteroventrals. ♀: parafacial with a shining patch at the level of antennal insertion; mid femur with a few posteroventral setae in basal half, and with 2–3 anteroventrals before apex and, sometimes, a further seta near base of femur (Fig. 6); hind femur with a complete anteroventral row as in ♂ ....... D. fasciculata (Stein)
- 3 postsutural dorsocentral setae. Scutellum with several strong setulae on ventral surface.Anepimeron often with a few setulae. ♂: mid and hind femora each with complete rows of anteroventral and posteroventral setae. ♀: parafacial without a shining patch in upper part; mid femur without posteroventral setae, on anteroventral surface with 1 seta near base and 2 very short, almost spinulose setae just before apex; hind femur with a sparse row of anteroventrals.............. D. sororcula sp.nov.
