Papp, L.: Three new species and a new subspecies of Meoneura from the Alps (Diptera, Carnidae)

One damaged female in the HNHM (left fore leg and wings lost) with data: Austria, Festkogel, 2300 m, dwarf shrub heath, G.-P. csapda [Gregor-Povolny trap], 1974. VII. 17., leg. BAJZA & PAPP, may belong to this species but it was not designated as paratype. Measurements in mm: body length 1.58 (holotype), 1.75, wing length 1.60 (both), wing width 0.62, 0.65 (paratypes). Body and legs all black. Frons unicolorous black. Frontal triangle bright shining, rather long, 4/5 length of frons. Facial carina narrow, flagellomere globular. Three pairs of vibrissae, one upcurving genal bristle behind them and one strong genal bristle at the middle of gena. Palpi slender, ca. twice longer than flagellomere. Mesonotal microchaetae comparatively long, 0+3 dc pairs, though 2 anterior pairs much shorter than posterior pair, as in M. flavifacies. Costal vein yellow, other veins dirty white, alar plane greyish. Stronger fringe on 2/5 of the third costal section. Crossvein r-m 0.60 mm, dm-cu 0.052 mm, intercrossvein section 0.095 mm. Knob of haltères dirty white, stalk grey. Fore coxa medially with a strong ventral seta. Fore femur posteroventrally with 3 longer setae. Epandrium with several long setae but only ventrally. Surstylus (Fig. 4) large, medially curved, much longer than height of epandrium. Lamella rather short with several medium-long setae. Parameres rather large with blunt apex. Meoneura falcata sp. n. is probably a member of the M. flavifacies species-group. Its characteristically long sickle-shaped surstylus makes it easily recognisable. Contrary to flavifacies, its epandrium bears long setae only on its ventral surface. The other species of the group differ by the armature and ratios of the genital parts. Figs 1-3. Meoneura species, male genitalia. 1 = M. longifurca sp. n., holotype male, end of abdomen in sublateral view; 2 = M. carpathica L. PAPP, holotype male, left lamella and surstylus; 3 = M. carpathica pseudoflavifacies ssp. n., holotype male, right lamella and surstylus. - Scales: 0.2 mm for Fig. 1, 0.1 mm for Figs 2-3
