03B7BE36677FFFF3FDC4FD72FEE86E90.taxon	diagnosis	Differential diagnosis Cheilosia (Montanocheila) albipicta sp. nov. is most similar to C. (M.) picta sp. nov., and can be distinguished by the black pilosity of C. picta sp. nov. laterally on tergites III – IV, while C. albipicta sp. nov. has black pilosity only on postero-lateral margin of tergite III. Cheilosia albipicta sp. nov. has a distinct shape of the superior lobe of the male genitalia, not shared with any other member of the subgenus (e. g., Fig. 3 D – F).	en	Barkalov, Anatolij V., Ståhls, Gunilla (2022): Cheilosia (Diptera, Syrphidae: Rhingiini) of Nepal with descriptions of 29 new species.

03B7BE366765FFF9FDE4FB64FEE86DCC.taxon	diagnosis	Differential diagnosis Cheilosia (Montanocheila) brevimontana sp. nov. has a strikingly dense pilosity of the body. Among the Nepalese taxa C. (M.) brevimontana sp. nov. is most similar to C. (M.) nigella sp. nov., for distinguishing characters see under C. (M.) nigella sp. nov. From this and all other congeners the new species can be distinguished by the following combination of characters: broad frons and gena, basoflagellomere broader than long, dense mesonotal pilosity with admixed shorter yellowish and long black pilosity, and dense pollinosity on medial parts of scutum and scutellum.	en	Barkalov, Anatolij V., Ståhls, Gunilla (2022): Cheilosia (Diptera, Syrphidae: Rhingiini) of Nepal with descriptions of 29 new species.

Taxonomic remark The description of Cheilosia (M.) distincta Barkalov & Cheng, 1998 agrees with the description of Cheilosia hirticincta Brunetti, 1915 in almost all described characteristics. The studied specimens from Nepal, one male and six females, have basoflagellomere reddish-brown with light greyish dusting and blackish dorsal margin (described as black with greyish dusting in Cheilosia distincta and C. hirticincta). The NHM (London) has six male specimens identified as Cheilosia hirticincta Brunetti. The structure of the male genitalia of Cheilosia (M.) distincta and C. hirticincta is very similar. However, we have not been able to locate and study the type material of C. hirticincta to evaluate a possible synonymy of C. distincta.	en	Barkalov, Anatolij V., Ståhls, Gunilla (2022): Cheilosia (Diptera, Syrphidae: Rhingiini) of Nepal with descriptions of 29 new species.

03B7BE366756FFCBFD9CF9D0FE026AB4.taxon	description	Description Female LENGTH. Body 9.4 – 13.4 mm, wing 8.8 – 10.9 mm. HEAD. Face broad, in anterior view distinctly widened ventrally, antero-ventrally protruded, shiny black, covered with fine grey pollinosity; facial tubercle moderate in size, laterally compressed and distinct; parafacia relatively broad, ventrally shiny adjacent to face and dorsally grey pollinose, long yellow pilose; gena broad, with slight grey pollinosity and long pale (yellow) pilosity. Frons anteriorly broad and posteriorly narrower, with densely punctured lateral furrows and very fine medial furrow, in anterior ¼ with narrow stripes of pollinosity adjacent to eyes, covered with rather short, dense, yellow pilosity; lunule brownish or yellow, antennal pits separated. Scape black or brownish, pedicel basally black and pale-brown apically, basoflagellomere oval, distinctly enlarged, orange basally and brownish apically, arista long, narrow, black, bare. Vertex with yellow pilosity, ocellar triangle equilateral. Occiput with yellow pilosity. THORAX. Postpronotum black, grey pollinose and yellow pilose. Scutum fine-punctured, shiny black, grey pollinose only laterally anterior to transverse suture; covered with dense, long, erect yellow pilosity, without black bristles laterally; scutellum with longer yellow pilosity, sometimes also with a few black pilosity on disc. Pleura moderately densely greyish-yellow pollinose, and with dense, erect, long, yellow pilosity. LEGS. Fore coxa black, densely grey pollinose and yellow pilose, without baso-lateral spur; femora shiny black with yellow tips, fore and mid femur posteriorly and hind femur antero-ventrally with long yellow pilosity; tibia mostly yellow, fore and mid tibia brownish in apical part, hind tibia yellow in basal ⅓ and on tip and brownish-black in other part; all tarsi yellow ventrally, dorsally fore and hind tarsi black, mid tarsus yellow with black 5 th segment. WING. Slightly brownish anteriorly, completely covered with microtrichia, Rs with short yellow and black pilosity along all length, inner angle between veins M 1 and R 4 + 5 right. Haltere and calypter yellow. ABDOMEN. Broadly oval, in broadest part slightly broader than scutum at level of wing base, shiny black with erect, yellow pilosity, laterally longer on tergites and shorter medially. Taxonomic remark Barkalov & Peck (1997) described Cheilosia erratica based on one male from Tajikistan. No subgeneric classification was indicated, but the authors noted that among the species known from Tadzikistan, C. erratica was most similar to C. (Montanocheila) heptapotamica Stackelberg, 1963. Barkalov & Cheng (2004: 327) described Cheilosia (Montanocheila) nigriventris from China, Xizang [Autonomous Republic of Tibet], based on a male holotype and one male paratype. Body lengths of C. erratica and C. nigriventris are 12.7 mm and 11 – 11.5 mm, respectively. The colour of the pilosity of abdominal terga are reddish yellow in C. erratica, but yellowish in C. nigriventris. Both described taxa share the same, distinct structure of the male genitalia, especially of the superior lobe. The mtDNA COI barcode is identical among the tested samples of C. erratica from Tajiikistan and C. nigriventris from Nepal (Fig. 1). Based on the high similarity of structures of male genitalia and the identical DNA barcode sequences we consider C. nigriventris a junior synonym of C. erratica. We here provide the description of the female sex of Cheilosia erratica based on specimens from Nepal (provinces Maharigaon, Bagmati and Mahakali, and Kathmandu area) and Tajikistan.	en	Barkalov, Anatolij V., Ståhls, Gunilla (2022): Cheilosia (Diptera, Syrphidae: Rhingiini) of Nepal with descriptions of 29 new species.

03B7BE366736FFA5FD9CFA22FE556A38.taxon	diagnosis	Differential diagnosis Barkalov & Cheng (1998) described Cheilosia lucida based on the male sex, and the taxon was placed in the subgenus Convocheila Barkalov, 2002. Barkalov & Cheng (2004) described the female. The structure of the distiphallus (apical sclerite of the aedeagus) and the shapes of the strongly asymmetric superior lobes and surstylus are very different from other species of Convocheila (see Barkalov 2002: 230; Barkalov & Cheng 2004: 395; Radenkovic et al. 2020). In addition, Cheilosia lucida has a characteristic lustrous green shine (reflection) of the thorax and strong black bristles on scutellum margin, characteristics not shared by other members of the subgenus Convocheila. Thus, the subgeneric classification of this species requires further study. From all species of Cheilosia, C. lucida differs by the combination of the mentioned characters.	en	Barkalov, Anatolij V., Ståhls, Gunilla (2022): Cheilosia (Diptera, Syrphidae: Rhingiini) of Nepal with descriptions of 29 new species.

Cheilosia versa sp. nov. is also similar to Cheilosia (Neocheilosia) komabaensis Shiraki, 1968 (see figs in Barkalov & Ichige 2016), both species have longer pile latero-dorsally on the face, but C. versa sp. nov. differs by having pilosity in lower part of face and yellow maculae laterally on frons, and parafacia yellow pollinose.

03B7BE366704FF98FDC0FB5BFEE86BD6.taxon	diagnosis	Differential diagnosis Cheilosia (Cheilosia) weiperti sp. nov. is a slender, comparatively short species, with moderately long and dense pilosity, with a typical structure shared by taxa of Cheilosa s. str. of the distiphallus (apical sclerite of the aedeagus-complex). Cheilosia (C.) weiperti sp. nov. differs from all species of Cheilosia by set of the following characters: face protruded with facial tubercle in lower part, facial tubercle of distinct shape, scutellum with long, black, bristle-like pile (much longer than length of scutellum), antennae black, mesonotum black, fore coxa without baso-lateral spur. The species has a very pronounced sexual dimorphism, especially in colour of the legs. A similar shape of face, wing venation, and occurrence of males and females simultaneously at the same locality lends support to their conspecificity. Cheilosia weiperti sp. nov. is most similar to C. suspecta Barkalov & Cheng, 2004 (Fig. 62), and can be differentiated by characteristic shape of superior lobe.	en	Barkalov, Anatolij V., Ståhls, Gunilla (2022): Cheilosia (Diptera, Syrphidae: Rhingiini) of Nepal with descriptions of 29 new species.
