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

Mesonotum with thick grey microtomentum. Anterior dorsocentrals very short, actually I can recognize only 1 pair, which is shorter than half of the posterior dc. Fore femur with 3 long posteroventral bristle pairs. Costal vein yellow, other longitudinal veins greyish yellow, alar plane greyish. Stronger fringe of costal vein present on nearly the whole length of third costal section. Knob of haltères white, stalk brown. Abdominal sterna long and narrow, similar to those of the related species. Phallus large, almost bulbous with many setulae on ventral surface. Only an in situ figure of lower magnification (and of lower quality) was made on the holotype, since I do not want to dissect it (I found the paratype after depicting the holotype in another material). However, the details of its genitalia are very characteristic (Fig. 1): epandrium extremely small with only 1 longer bristle pair dorsally; 1 pair of long though not extremely long setae on gonopods; no lamellae; surstylus long, very characteristic in shape (Fig. 1), with medium-long setae apically. Surstylus much longer than height of epandrium. Meoneura longifurca sp. n. is related to M.forcipata SABROSKY, 1959 (Nearctic and also in Mongolia, see PAPP 1976): its epandrium is similarly very small, there is no trace of lamellae in the genitalia, etc. I do not think M. perlamellata HENNIG, 1937 (Palestine, now Israel; cf. Textfig. 70 of HENNIG 1937) would be closely related. The latter species has two pairs of very long setae on gonopods (? or on hypandrium), the new species has only one pair of much shorter bristles there. The epandrium of perlamellata is comparatively large and its knob of haltères is blackish. Otherwise also the surstylus of perlamellata is much longer than in longifurca. * * * Acknowledgements - My most sincere thanks are due to Drs BERNHARD MERZ (Institut für Pflanzenwissenschaften, Eidgenössische Technische Hochschule, Zürich) and GERHARD BÄCHLI (Zoologisches Museum der Universität Zürich) for the loan of numerous materials from their collections, including carnids.
