Meoneura baechlii, Stuke & Barták, 2019

Stuke, Jens-Hermann & Barták, Miroslav, 2019, Records of Carnidae from the collection of Miroslav Barták (Diptera: Carnidae), with the description of five new species, Zootaxa 4567 (2), pp. 326-346 : 331-335

Meoneura baechlii spec. nov.

( Figs. 7–10 )

Holotype ♂: (1) „I: Mte. Terminillo / meadow nr. wood / 42.26N / 13.07E 2000 m / Barták, 4.viii.1988 “; (2) „ Holotypus / Meoneura baechlii / spec. nov. ♂ / det. Stuke 2018“.

The holotype is deposited in the collection of the Czech University of Life Sciences, Czech Republic, Prague (CULSP). The specimen was glued on a card point and the abdomen was glued, too. Therefore, it was necessary for examination to macerate the complete specimen and store it in a glycerine microvial pinned underneath the label. The specimen is in a poor condition with most setae of the body surface broken and the thorax is broken. Therefore, the description of head and thorax is incomplete.

Description of holotype (male). Length about 1.6 mm. Wing length 1.2 mm. Head height 0.3 mm.

Head black. Antenna black to dark brown. Arista without pubescence. Maximum eye length: maximum eye height = 1. Posteroventral margin of gena closest to eye margin: maximum eye height = 0.5. Frons microtomentose, frontal triangle shining to subshining. Frontal triangle distinct, reaching about 1/2 distance from anterior ocellus to frontal margin. Carina narrow. Postcranium microtomentose. Prementum about as long and slightly wider than labellum. Palpus brown, about 1/2 as long as the haustellum.

Scutum with 1 long posterior dorsocentral seta, other setae or scars of setae could not be detected. Costa with no obvious setae beyond radial vein R 1. Wing hyaline, veins light yellow to yellow brown. R 4+5 slightly curved to apex of wing. Knob of haltere whitish yellow, base of haltere brown. Legs black to brown. Fore femur apically with 2 strong posteroventral setae, other setae could not be recognized. Hind femur apically with 1 strong anteroventral seta. Length metatarsus 2: length tibia 2 = 0.5.

Tergites with no obvious depressions or tufts of setulae. Abdominal pleura with scattered setae on abdominal segments 4–5. Abdominal segments 1–5 moderately narrow, width of tergite 3: length of tergite 3 = 2.0. Tergites 2–4 each with 1 distinct lateral seta at the posterior margin, tergite 5 with an obvious long lateral seta and 3 long submedial setae at the posterior margin. Sternite 5 almost rectangular ( Fig. 10 ). Sternite 5 with scattered setae. Midventral tergite 7 distinct. Protandrium long, about as long as epandrium and about 0.8 of length of tergite 5. Epandrium apically with long setae and with several smaller setae ( Fig. 7 ). Maximum length dorsally in the middle of epandrium: maximum width of epandrium = 0.8. Cerci distinct, distinctly projecting, and with a few setulae only. Subepandrial sclerites sclerotised and distinctly separated by the hardly sclerotised hypoproct. No setula recognized on subepandrial plate. No proceeding of hypoproct. No tooth on subepandrial plate. Surstylus as Figs. 7, 8 : bifurcated, with a smaller, slightly stronger sclerotized, short, pointed dorsal part and a larger, anteriorly rounded ventral part. Dorsal part of surstylus dorsally with several obviously long setae and apically with inconspicuous short setulae. No additional lamella recognized. Postgonite as in Fig. 9 : distinctly sclerotised, with a broad base, slightly elongated, pointed, apically not bent like a hook. Distiphallus slightly longer than epandrium and surstylus, covered with dense black setulae that form a dark surface over almost the complete distiphallus. Basiphallus obviously sclerotised, long, narrow, at its base not widened.

Diagnosis. Meoneura baechlii has a distinctive postabdomen with a bifurcate surstylus ( Figs. 7, 8 ). The ventral part of surstylus is larger than the dorsal part. Only the dorsal part has long setae that are about twice as long as surstylus. The ventral part has only a few less conspicuous setae. Several long setae arise apically on the epandrium and are about as long as length of epandrium ( Fig. 7 ). The only species that is similar to M. baechlii due to the shape of the surstylus is M. nevadensis Lyneborg, 1969 . Concerning the original description M. nevadensis has only 2 small setae at the dorsal part of the surstylus and no setae at the ventral part ( Lyneborg 1969: 43, Fig. 21 ). M. nevadensis has some long setae apical at the epandrium, too, but these are only about as long as height of epandrium.

Etymology. This species is dedicated to Prof. Dr. Gerhard Baechli (Zürich). No dipterist collected more Carnidae and Gerhard Baechli´s contribution to the knowledge of this hardly known family cannot be overstated.

Distribution. Meoneura baechlii is hitherto only known from the locus typicus Monte Terminillo of the Abruzzi Apennine ( Italy) at a height of 2000 meter.
