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

Meoneura helvetica sp. n. (Figs 5-7) Holotype maie (coll. Bächli/ZMZ): CH [Switzerland]: Ftan/Clünas, GR, 5.VIII.1996, Merz & Bächli. Paratypes: 3 males (2 coll. Bächli/ZMZ, 1 HNHM): same data; 1 male (ETZH): ibid., 2100 m; 2 maies (coll. Bächli/ZMZ, HNNM): Oberwald VS, 13.-15.8.1975, G. Bächli coll.; 1 male (coli. Bächli/ZMZ): CH: Guttet VS, 27.-31.7. 1993, G. Bächli leg.; 2 maies (coll. Bächli/ZMZ, HNHM): ibid., 27.7.-6.8.; 1 male (coli. Bächli/ZMZ): Lenzerheide GR, 11 .-14.VIII.1988, G. Bächli leg. Measurements in mm: body length 1.63 (holotype) 1.46-1.67 (paratypes), wing length ca. 1.55 (holotype, not precisely measurable), 1.25-1.66 (paratypes), wing width 0.66 (holotype), 0.57-0.67 (paratypes). Body black, subshining, legs all black. Frons all black with some silky shine, frontal triangle bright, long, extended nearly to lunule (88.5% length offrons). Palpi slightly longer than flagellomere. Facial carina very narrow. Fore femur with 2 long posteroventral setae. Alar plane grey, costal vein and other longitudinal veins greyish yellow. Stronger fringe on 3/4 of the third costal section. Knob of haltères white, stalk brown. Epandrium rather small with a number of medium-long bristles. Both surstylus and lamella with numerous long bristles (Fig. 5). There is no view from where both surstylus and lamella would be seen in their widest extension. So Fig. 6 shows lamella in its widest, and surstylus is depicted in Fig. 7 at its longest extension. Surstylus and lamella are partly fused. Meoneura helvetica sp. n. is probably related to M. asiatica L. PAPP, 1976; at least other European species of the M. flavifacies-group do not seem to be closely related. The types of M. asiatica are newly studied and although the original figures are only caricatures of the genitalia, the shape of surstylus of M. asiatica - being pointed at apex - is really different from that of this new species (Figs 5-7, compare Fig. 4 of PAPP 1976). Furthermore, the length of setae on lamellae and on surstyli are less different in this new species than in asiatic-a, where surstylar setae are only half as long as those on its lamellae (Fig. 3 of PAPP 1976). Meoneura longifurca sp. n. (Fig. 1) Holotype male (coll. Bächli/ZMZ): Switzerland: Zuoz-Nüd GR, 7.VIII.1996, Merz & Bächli leg. Paratype male (HNHM): CH: Guttet VS, 2.-3.8.1993, G. Bächli leg. Measurements in mm: body length 1.67 (holotype), 1.80, wing length 1.70, 1.80, wing width 0.64, 0.71. Body and legs dull black. Frons dull, frontal triangle extended to 9/16 of frons, not strongly shining. Face dark greyish but anterior margin of frons yellow on its anterior 1/8. Palpi very short, not longer than flagellomere.
