03F01454CE14FFD4FD24FA77C643FADE.taxon	materials_examined	Type locality: Austria. Lectotype (designated by Hurkmans, 1993: 176), examined: male, Austria, (NHMW, Egger collection), [specimen dry pinned]. Original label: ‘ Austria Alte Sammlung / Merodon aberrans Egger’. This designation was based on a syntype in good condition from the Vienna Museum.	en	Vujić, Ante, Radenković, Snežana, Tubić, Nataša Kočiš, Likov, Laura, Popov, Grigory, Rojo, Santos, Miličić, Marija (2023): Integrative taxonomy of the Merodon aberrans (Diptera, Syrphidae) species group: distribution patterns and description of three new species.

03F01454CE17FFDBFF20FA3FC55BF94B.taxon	materials_examined	Type locality: Italy, “ Sanseverino, Monte Vergine ” [= near Naples]. Information concerning the Palma material was missing, type material presumably lost. Synonymy was cited in different publications (Peck, 1988; Hurkmans, 1993). Description, including the Merodon kneri Mik, 1867: 415. Type locality: Ukraine, “ Galizien ”. Original description was based on an undefined number of male and female syntypes. One syntype was located in the Vienna Museum and is designated as a lectotype. Lectotype (designated here): male, Ukraine (Kreise Czortkow, Podol), (MNHN), [specimen dry pinned]. Original labels: ‘ Merodon kneri / Mik’, ‘ 1969 ’, ‘ LECTOTYPE of Merodon kneri Mik / designated by Vujic A. ’. This designation was based on the good condition of the specimen, which was a well-preserved male with clearly visible characters. Synonymy was cited in different publications (Peck, 1988; Hurkmans, 1993). Diagnosis: Large (12 – 15 mm), dark species with bluish to brown or purple lustre; antennae black (figs. 2 A, 2 C – D, 2 F, 29 C, F); basoflagellomere elongated, about 1.5 times as long as wide (fig. 29 C, F); abdomen narrow, elongated (figs. 1, 5 A); body covered with yellow – grey pile, except fascia of black pile between wing bases (fig. 5 C) and black pile on terga 2 – 5 medially in females; legs black (figs. 3 A, 4 B); metafemur elongated, about 5 times longer than wide, ventrally covered with pile, as long as half of its width (at least apically) (fig. 3 A); terga 2 – 4 each with a pair of narrow, white pollinose, triangular fasciate maculae (fig. 5 A, B). Male genitalia: posterior surstyle lobe quadratic (fig. 6 A: pl) with well-developed interior accessory lobe (fig. 6 B: il); anterior surstyle lobe large, oval to rectangular (fig. 6 A: al); cercus rectangular (fig. 6 A: c); lingula elongated and narrow (fig. 6 C: l). Similar to Merodon flavitibius, from which it differs in narrower metafemur (fig. 3 A), and completely black tibiae and tarsi, while partly reddish – yellow in M. flavitibius (fig. 3 C). Also differs from M. hermonensis sp. nov. in having longer ventral pilosity on metafemur, as long as half of its width, at least apically (fig. 3 A), while it is about 1 / 5 of its width in M. hermonensis sp. nov. (fig. 3 B). Distribution and biological data: Range (fig. 7): through much of central Europe; from Germany, across the Czech Republic and the Alps (France, Switzerland, Austria) on to Ukraine and southern European Russia; in southern Europe from Spain eastwards to Italy, Albania, the former Yugoslavia and Greece and further on to Turkey, including Mediterranean islands e. g., Crete. Several authors mention the presence of this species in Morocco (Séguy, 1961; Claussen, 1989; Dirickx, 1994) and in Spain (Dirickx, 1994; Marcos-García et al., 2007) without referring to the precise localities where the species occurs. Here, we designate the exact locality from the Spanish records mentioned in the previously published literature. Records from Portugal (Marcos-García et al., 2007; van Eck, Downloaded from Brill. com 08 / 29 / 2023 02: 13: 25 AM via free access 2011), albeit possibly true, could not be accurately established. Findings from Lebanon certainly belong to M. hermonensis, while records from Iran (Khaghaninia et al., 2011; Samin et al., 2016) could be either M. brevis or M. flavitibius, but based on morphological similarity, we suppose it is M. flavitibius. Records from Morocco remain uncertain and unconfirmed. Based on Speight (2020), this species is connected with unimproved, calcareous montane grassland and patchily-vegetated, herb-rich open areas within the Abies forest zone, in the Alps and Pyrenees. At lower altitudes, including Balkanic thermophilous Quercus forest (fig. 34 D), in South East Europe M. aberrans has been recorded flying high among Tilia trees in flower. In Ukraine, this species inhabits steppe landscapes in the steppe zone and small steppe refugia in the more northern forest regions, excluding very Downloaded from Brill. com 08 / 29 / 2023 02: 13: 25 AM via free access dry steppe grassland in the southern parts of the country. Flowers visited: presumably Apiaceae (Chaerophyllum, Seseli, Sium, Torilis, etc.), Galium, Tanacetum, Tilia. Flight period: May-July and August at higher altitudes. Developmental stages: not described, but in laboratory conditions the larvae of the species feed on Leopoldia comosa bulbs (Popov, unpubl. data).	en	Vujić, Ante, Radenković, Snežana, Tubić, Nataša Kočiš, Likov, Laura, Popov, Grigory, Rojo, Santos, Miličić, Marija (2023): Integrative taxonomy of the Merodon aberrans (Diptera, Syrphidae) species group: distribution patterns and description of three new species.

03F01454CE1CFFDFFFC3FD9DC034FE8B.taxon	materials_examined	Type locality: Armenia. Original description was based on an unknown number of syntypes, two of them were located in the Paramonov’s collection (SIZK, examined): Lectotype: male with labels: [N 317], [Инаклю (= Inaklyu, modern Antarut village, 40.35 N, 44.266667 E, asl 1450 m) / Эчмиадз. у.

Paralectotype: female with labels: [N 318], [г. Карны-Ярых (KarnyMount Yarykh, = Mount Ara, 40.4056 N 44.4522 E, asl 2614 m) / Эчмиадз. у. / Эрив. г. (= Yerevan Region, Armenia) 26. vii. 24.], [Merodon / aberrans Egg. / var. flavitibius / var. nov. ♀ Typus / Paramonov d.] (SIZK). Note. In the original description, only the type locality is given, namely “ Patria: Armenia ”. The exact number of types is unknown, as it is not specified by the author of the species (Paramonow, 1926: 153). The types were considered lost (Liepa, 1969: 20; Hurkmans, 1993: 205). In Peck (1988: 166), taxon was given as subspecies Merodon aberrans flavitibius Paramanov (sic!), 1926, according to article 45 g (II) ICZN (1985). Hurkmans (1993: 176) also left the subspecific rank for the taxon. He also erroneously indicated that Paramonov published the name with a subspecies status (ibid.). We designate here the male as the lectotype, and the female as the paralectotype.	en	Vujić, Ante, Radenković, Snežana, Tubić, Nataša Kočiš, Likov, Laura, Popov, Grigory, Rojo, Santos, Miličić, Marija (2023): Integrative taxonomy of the Merodon aberrans (Diptera, Syrphidae) species group: distribution patterns and description of three new species.

Hermann]; red [Paralectotypus / Merodon / hamifer Sack, 1913 / G. V. Popov des. 2007]. Note. The species was described from two specimens from Greece (“ Sammlung Hermann ”) and two from Anatolia (“ Sammlung Lichtwardt ”), which were considered syntypes according to ICZN article 73.2 (1999). A redescription of the species was given by Paramonov (Paramonow, 1936: 5) on the basis of two Sack’s-type specimens transferred from Munich. Hurkmans (1993: 181) fixed the lectotype and paralectotype for two syntypes (male and female) of this species from Turkey (Lichtwardt collection, P. Sack determination), so here we mark the SIZK specimens from Paramonov’s collection as paralectotypes according to article 74.1.3 ICZN (1999). Diagnosis: Large (12 – 15 mm), dark species with bluish to brown lustre (fig. 16 C-E); metafemur with modified apicoventral triangular lamina dislocated from the apical part (fig. 15 A – B); basotarsomere of metaleg with distinct basoventral bulge (fig. 15 A: marked with arrow); protarsus extended as in genus Platycheirus Lepeletier & Serville, 1828 (fig. 15 C – D), less expressed in female; tarsomere of proleg usually yellow, with small basomedial triangular black maculae ventrally (fig. 15 D); antennae orange – reddish; basoflagellomere very elongated, 2.5 times as long as wide (fig. 16 A, B); abdomen narrow and elongated (fig. 16 C, D); body covered with yellow – grey pile, except fascia of black pile between wing bases (fig. 16 E) and black pile on terga 2 – 5 medially in female; metafemur mostly black, pro- and mesofemora yellow apically, while tibiae and tarsi of the same legs mostly yellow; metafemur about 3.8 times longer than wide (fig. 15 A, B); terga 2 – 4 each with a pair of narrow, white pollinose, triangular fasciate maculae (fig. 16 C, D); male genitalia: posterior surstyle lobe quadratic (fig. 17 B: pl), with well-developed interior accessory lobe Downloaded from Brill. com 08 / 29 / 2023 02: 13: 25 AM via free access (fig. 17 A: il); anterior surstyle lobe large and oval (fig. 17 B: al); lingula long and very narrow (fig. 17 C: l). Distribution and biological data: This species is distributed in Greece and Turkey (fig. 8). In Greece it has been found on the East Aegean islands of Chios, Lesvos, and Samos (Speight, 2020; Vujić et al., 2020 c). This species prefers deciduous Mediterranean Quercus (Vujić et al., 2011, 2020 c) and Castanea forests (Ricarte et al., 2012). Flowers visited: Apiaceae (white), Foeniculum vulgare, Ferula.

An additional female specimen was present in the collection from the locality Hakkari, Sat Mountains, south of Lake Sat, 7. viii. l 983, leg. Warncke, which it had the same data as two males and one female designated as paratypes, and was not labeled as paratype. One additional male specimen was labeled as paratype, but it was not listed under the type material in Hurkmans (1993). Diagnosis: Large species (11 – 14 mm), long pilose, dark with olive to brown lustre (fig. 9 C, D); antennae dark brown to reddish (fig. 9 A, B); basoflagellomere elongated, 1.7 times as long as wide (fig. 9 A, B); abdomen less elongated than in other species from the Merodon aberrans group (fig. 9 C); body covered with yellow – grey pile (fig. 9 C, D); femora black, tibiae and tarsi partly reddish – yellow (fig. 10 A, B); metafemur about 3.8 times longer than wide, in male with slightly concave ventral margin, covered with a long pile, almost as long as or longer than its width (fig. 10 A); terga 2 – 4 each with a pair of narrow, white pollinose, triangular fasciate maculae (fig. 9 C); male genitalia: posterior surstyle lobe quadratic (fig. 11 A: pl), with poorly developed interior accessory lobe (fig. 11 B: il); anterior surstyle lobe large, rectangular to oval (fig. 11 A: al); lingula elongated and narrow (fig. 11 C: l). Very similar to M. brevis, from which it differs in longer pilosity on ventral margin of metafemur (fig. 10 A, B), a ratio of length of longest pile to width of metafemur is 0.7, compared with 0.45 in M. brevis (fig. 30 A, B), and the absence of black pile on apical part of metafemur (fig. 10 A, B), but which is present in M. brevis (fig. 32 A, B). Distribution and biological data: This species is recorded only in Turkey (fig. 8). It has been collected at high altitudes only. Flight period: June-August. In view of the few specimens collected, the split occurrence does not necessarily indicate that M. warneckei is bivoltine (Hurkmans, 1993).
