Tibiae mixed black and yellow pilose. Tarsi short black pilose or mixed black and reddish-brown pilose dorsally, ventral surface of pro- and metatarsi usually reddish-brown pilose, or intermixed with black hairs. Tarsi of mesoleg ventrally with black setulae.</p><p>ABDOMEN. Tergites medially brownish pruinose (best seen if viewed obliquely from front), shiny on sides of tergites 2–4; tergites 1–3 with long mixed black and yellow hairs on disc, sides of tergite 1 and anterolateral corners of tergite 2 with long yellow hairs, remainder of lateral margin of tergite 2 and entire margin of tergite 3 with black hairs, tergite 4 with black hairs. Sternites faintly greyish-brown pruinose; sternite 1 yellow pilose; base and sides of sternite 2 with long mixed black and yellow hairs, sides of sternites 3–4 long black pilose, hairs on the median parts of sternites 2–4 black and appressed.</p><p>GENITALIA. Right and left surstyli and gonostyli slightly asymmetrical; ventral margin of surstylus with a shallow basal convexity; hypandrium in lateral view about 1.2 times as long as wide; sclerite of distiphallus broadly fused dorsally, with long dorsal lobes.</p><p>Female</p><p>LENGTH. Body 6–7 mm; wing 5.4–6.2 mm.</p><p>The ♀ differs from the ♂ in the following characters: integument more shiny; pilosity much shorter. HEAD. Eye hairs short, about ¼ or less of width of postpedicel. Frons not wide, at level of lunule about 0.3 times as wide as maximum width of head, with a shallow transverse sulcus at level of about lower 1/3 of frons; lateral channels narrow, widening from inner dorsal corner of eye towards transverse sulcus, enclosing a small semicircular area of dense grey pruinosity at about median 1/3 of frons, remainder of frons shiny; hairs on frons erect, as long as one third width of postpedicel, black. Occiput dorsally much wider than in male, grey pruinose, with short black hairs. Gena long yellow pilose. Face bare, at level of facial tubercle about 0.3 times as wide as maximum width of head, shiny; parafacia orange on dorsal half, at level of tentorial groove about half as wide as diameter of protibia, pale pruinose and with short yellow hairs. Lunule orange. Scape, pedicel and 3 rd antennal segment bright orange, 3 rd antennal segment larger than in male.</p><p>THORAX. Scutum and scutellum shiny, pale pruinose sub-median vittae anterior on scutum reduced to spots; scutum with semi-erect short black hairs. Pleurae faintly grey pruinose, hairs yellow and black, shorter and less dense than in male. Calypter whitish, with orange rim and yellow fringe. Haltere with brownish or yellowish stem and yellow knob.</p><p>LEGS. Legs black, but basal 1/4 of protibia, 1/3 of mesotibia and basal 1/10 of metatibia, and often extreme apices of tibiae and femora reddish-yellow; femora with both black and yellow hairs; ventral surface of metafemur basally without black setulae; tibial hairs and tarsi as in male.</p><p>ABDOMEN. Tergites with less dense pruinosity compared to male, mainly with black hairs, except on tergite 1 and in anterolateral corners of tergite 2 with yellow hairs. Sternites lightly pruinose, short black and yellow pilose; hairs erect on sternites 1–2 and on anterior corners of sternite 3, remaining hairs more or less appressed.</p><p>Distribution</p><p>Finland, Russia.</p><p>Differential diagnosis</p><p>Similar in appearance to extralimital Cheilosia komabaensis, see Barkalov &amp; Ichige (2016) for a differential diagnosis with that species. Similar in appearance to Cheilosia luteicornis and C. morio but differs as follows: body length shorter. Face narrower. Basal half of wing with yellow veins. Legs with less extensive yellowish parts. ♂: anterior eye angle smaller. Anterior part of frons shiny. Haltere knob yellow. Lateral margin of tergite 1 and anterolateral corner of tergite 2 with yellow hairs. Surstylus basally narrower than in C. morio, and shorter than in C. luteicornis . ♀: scape and pedicel orange. Postocular orbit dorsally with black hairs. Scutum with semi-erect black hairs. Tergites 3–4 with black hairs. Moreover, both sexes differ from C. morio by having sides of face not haired and from C. luteicornis by having parafacia above posterior tentorial pit strongly compressed.</p></div>	https://treatment.plazi.org/id/03D4D13945108146FDB6FBEE30EF3B5A	Public Domain	No known copyright restrictions apply.

Genitalia: surstylus with a shallow basal convexity; hypandrium about 1.4 times as long as wide.</p><p>Remarks</p><p>Zetterstedt received the description of “ Eristl. lineata nov. spec. ♂ ” in a letter from P. Wahlberg, but he did not study the underlying specimen(s), nor other specimens of E. lineata (1843: 807–808). Subsequently Zetterstedt (1849: 3173, in a note under “31. E. melanopa ”) synonymized E. lineata under his C. morio . Among the Cheilosia materials in the Wahlberg and Boheman collections, now incorporated in the general Diptera collection of the NRM (H. Bartsch personal communication), the following historical specimens under the name Cheilosia morio could be located: 1) Wahlberg collection: 3 ♀♀ C. luteicornis, 1 ♀ C. morio; the specimens are without locality and other data but marked by a small coloured tag. These specimens cannot be syntypes, because of the female gender. 2) Boheman collection: under the name C. morio, there are 1 ♂ and 2 ♀♀ from “Holmiae” (= Stockholm), collected by Wahlberg and labelled by Boheman “Hlm./P.Wg.”. The label of the male agrees well with the type locality and the characters of the specimen agree with those given in the original description of E. lineata Wahlberg, and it is here accepted as the lectotype.</p></div>	https://treatment.plazi.org/id/03D4D139451F8141FE7AF9FA36223CF0	Public Domain	No known copyright restrictions apply.

Parafacia narrow, about 1/3 of the width of postpedicel. Face and frons slightly wider than in C. luteicornis . ♀ with hairs on scutum of about equal length, with only individual black hairs intermixed. ♂: face with a slight, but distinct haired bulge on each side, just dorsal to the facial prominence. Bases of pro- and metatibiae usually blackish or obscured reddish. Abdomen entirely black-haired. Calypter brownish-grey to blackish. Genitalia: surstylus with strong basal convexity; hypandrium about as long as wide.</p><p>Remarks</p><p>The holotype specimen bears labels with what could seem to be contradicting information on the locality, but there is no doubt that this specimen is the holotype collected in Lapland. The label mentioning E. lineata and Holmia is similar to other bottom-drawer labels used by Zetterstedt for species of which he had no material, and most likely this label was added to the specimen by Zetterstedt himself when he synonymized E. lineata with E. morio .</p><p>The type accords well with the original diagnosis and morphological description and with its subsequent additions (Zetterstedt 1843: 795), but the description of the facial hairs does not: The face of the male is described as “hypostoma nudum [!], nitidum, atrum [face bare, shiny, black] and later (Zetterstedt 1843: 795) as “epistomate bituberculate, nudo [!], nitido” [face bituberculate, bare, shiny black], by this giving the impression of a species with a face lacking hairs. Actually, the face of the holotype clearly has long, black hairs laterally below the antennal insertion, with individual hairs reaching the level of facial tubercle. As a consequence of this discrepancy between the description and the characters actually observed, C. morio was erroneously and almost consistently regarded as a species with a bare face throughout the central European literature. The nomenclatural consequences will be discussed below.</p><p>DNA barcoding</p><p>A total of 18 COI barcodes of 633 bp length representing four species of the subgenus Neocheilosia and additionally the barcodes of two species of the subgenus Convocheila (Barkalov 2002) and one species of the subgenus Montanocheila Barkalov, 2002 were used for the NJ distance tree (for specimen data and GenBank accession numbers see Table 2). The NJ tree (Fig. 6) consistently resolved the included male and female individuals of Cheilosia barovskii, C. luteicornis, C. morio and C. shiranesana in separate clusters, respectively. All the bootstrap values supporting the nodes of the species clusters were high (99–100%). The uncorrected interspecific pairwise distances among the included species of the subgenus Neocheilosia ranged from 2.96% (between C. luteicornis and C. morio) to 7.57% (between C. barovskii and C. shiranesana).</p></div>	https://treatment.plazi.org/id/03D4D1394518815BFDC6FE0436313B0E	Public Domain	No known copyright restrictions apply.
