03CE87F1744EFFE2C4A5FC58FF2B9F16.taxon	diagnosis	Diagnosis. Both sexes of H. ferruginea clearly differ from H. ingrica (figs 5 – 8) by the longer body, 9.0 – 13 mm (in H. ingrica, body length 5.5 – 8.0 mm), and plumose arista (fig. 3), with its branches> 2 × as long as the maximum diameter of the arista (in H. ingrica, arista with shorter microtrichia (fig. 7), the longest branches slightly longer than the maximum diameter of the arista). Additionally, H. ferruginea can be separated from H. ingrica by: hind coxae covered with numerous short black setae (Mutin & Barkalov, 1999) as well as katepisternum with several (8 – 12) long black setae posteriorly (fig. 4) (in H. ingrica, katepisternum without black setae, and hind coxae mostly with 2 – 3 long black setae only in outer posterior corner laterally and the same amount at the posterior edge, as on fig. 8); female tergite 2 (fig. 2) usually with pale anterolateral part that do not look like separate maculae (in H. ingrica, female tergites 2 and often 3 with pale maculae that look like a separate maculae (fig. 6), especially on tergite 2).	en	Prokhorov, A.

Prokhorov). D i s t r i b u t i o n: uncertain at present, due to confusion with M. aerosa (Loew, 1843) until recently, but known from Bosnia-Herzegovina, Czech Republic, Finland, France, Germany, Montenegro, Norway, Poland, Romania, Slovakia, Sweden, Switzerland (Maibach et al., 1994; Holinka & Mazánek, 1997; Vujić et al., 2001; Stănescu & Pârvu, 2005; Bartsch et al., 2009; Mielczarek, 2009; Haarto & Kerppola, 2014; Speight, 2018; Wakkie, 2019); Ukraine (first record). Diagnosis. Both sexes of M. parumplicata are very similar to M. aerosa (figs 11, 12, 15, 16, 19, 20). Male of M. parumplicata is similar to M. aerosa male in having thorax with black pile and surstyli without elongated apex, differing from M. aerosa by: weakly developed flattened facial tubercle (fig. 13) (in M. aerosa, facial tubercle distinctly elongated and pointed, as on fig. 15), scutum shining black (in M. aerosa, scutum, especially notopleuron and lateral side of scutum posterior to transverse suture with a slight bronze or copper tint), face broader (fig. 17), ratio of the maximum head width to the face width at the level just below the antennal base 1.95 – 2.0 (in M. aerosa, face narrower (fig. 19), this ratio is 2.2), surstylus (in lateral view) shorter and almost straight, with blunt apex (Maibach et al., 1994: fig. 8) (in M. aerosa, surstylus more elongated and slightly curved, with a more pointed apex; Maibach et al., 1994: fig. 3), superior lobe of hypandrium with short appendages (Maibach et al., 1994: fig. 9) (in M. aerosa, superior lobe of hypandrium with long appendages; Maibach et al., 1994: fig. 4). Genitalia of both species are prepared and compared with figures in Maibach et al. (1994). Other characters differing M. parumplicata male from M. aerosa male, such as conjunction of the vein M 1 with R 4 + 5 or the mesoanepisternal pilosity (Maibach et al., 1994; Van Veen, 2010) seems to be vague in our opinion. The most reliable and convenient characters are the shape and size of the facial tubercle, and genital structures.	en	Prokhorov, A. V., Popov, G. V., Shparyk, V. Yu.

03CE87F1744CFFE4C4A5FEBCFDCB9B69.taxon	description	Female of M. parumplicata is similar to M. aerosa female (figs 12, 16, 20) in having mesonotum with short adpressed pale pile; can be distinguished from it by: the scutum shining black (in M. aerosa, scutum is not so shining with bronze or copper tint), tergite 5 with mainly erect to semi-decumbent long pile (Bartsch et al., 2009), their length approximately equal to the width of hind basitarsus (in M. aerosa, tergite 5 with mainly adpressed short pile (Bartsch et al., 2009), their length less than the width of hind basitarsus), transition from upper to lower part of the face (lateral view) is smooth (fig. 14) (Bartsch et al., 2009) (in M. aerosa, transition from upper to lower part of the face is angular, as on fig. 16 (Bartsch et al., 2009 )), face broad (fig. 18), ratio of the maximum head width to the face width at the level just below the antennal base 1.9 – 2.0 (in M. aerosa, face narrow (fig. 20), this ratio is 2.1 – 2.15). Unfortunately, transition from upper to lower part of the face varies quite a lot (checked on own material). The clearest characters are shine and coloring of scutum (in females this character is more pronounced than in males), and pilosity of tergite 5. Note. Listed as a threatened species on the Balkan Peninsula by Vujić et al. (2001). Here we offer an updated key to males of the European species of the genus Melanogaster including a little-known species M. jaroslavensis (Stackelberg, 1922) with Eastern European distributional range.	en	Prokhorov, A.

03CE87F17448FFE8C4A5FD4CFE709807.taxon	diagnosis	Diagnosis. Only four Sphiximorpha species are known from Europe, and S. garibaldii is most similar to S. subsessilis (Illiger in Rossi, 1807) (figs 31 – 34, 39 – 42) in having frons with lateral or medial black vittae (Van Steenis et al., 2016) (in S. euprosopa (Loew, 1869), frons entirely yellow). Sphiximorpha garibaldii differs from very rare sub-Mediterranean S. petronillae Rondani, 1850 by the scutellum yellow with black posterior margin (in S. petronillae Rondani, 1850, scutellum entirely yellow). Female of S. garibaldi can be separated from S. subsessilis female by: face with a lateral yellow marking in the shape of an inverted hook (usually as on fig. 30) (in S. subsessilis, face with a lateral yellow marking not hook-shaped, as on fig. 34), pedicel shorter (fig. 29), ratio of it length to the width is 1.78 (in S. subsessilis, pedicel longer (fig. 33), ratio of it length to the width is 2.0 – 2.2), hind femur slender (in S. subsessilis, hind femur ventrally near the apex with a small thickening). These characters were based on Van Steenis et al. (2016), except measurements made on our material. Additionally, S. garibaldi clearly differs from S. subsessilis by the slender tergite 2 (fig. 35): ratio of the length of tergite to its width is 1.77 (in S. subsessilis, tergite 2 more robust (fig. 39), ratio of the length of tergite to its width is 1.25 – 1.43), distance between yellow maculae on tergite 2 (fig. 35) less than width of the macula (dorsal view) (in S. subsessilis, distance between yellow maculae on tergite 2 more than width of the macula, as on fig. 39), frons with two small transverse yellow maculae separated from lateral maculae (fig. 29) (in S. subsessilis, these maculae are fused with lateral maculae, as on fig. 33), hind femur yellow at base about one sixth of its length (fig. 36) (in S. subsessilis, hind femur yellow at base of at least a third of its length, as on fig. 40), mid basitarsus ventrally with yellow setulae (fig. 37), hind basitarsus entirely pale, and hind tarsus dorsally with only pale macrotrichia (fig. 38) (in S. subsessilis, mid basitarsus ventrally with black setulae (fig. 41), hind basitarsus blackish dorsally, and hind tarsus dorsally with numerous black macrotrichia, as on fig. 42). Our specimen, unlike the description of the species (Van Steenis et al., 2016), with scutellum almost black and with only small orange maculae in anterior edge (fig. 35) (in S. subsessilis, scutellum with broad yellow fascia anteriorly, as on fig. 39).	en	Prokhorov, A.

03CE87F17448FFE8C4A5FD4CFE709807.taxon	discussion	Probably some of the above additional characters may vary, for example the color of the pile on tarsus or the presence and shape of yellow maculae on frons, but our specimen clearly differs from S. subsessilis precisely on these characters. Note. Perhaps this is one of the most incredible new species for the fauna of Ukraine over the past few years because Ukrainian record is so far from the main range of this Southern European species. The specimen was found in a mixed forest with many old trees of Quercus robur, although the preferred environment of this species cited as “ thermophilous deciduous forest of Quercus pubescens with overmature trees and Quercus suber forest with overmature trees ” (Speight, 2018). This insect has been very sparsely recorded and is probably threatened at European level (Speight, 2018).	en	Prokhorov, A. V., Popov, G. V., Shparyk, V. Yu.

Diagnosis. At first glance, C. pachymera male looks like species of the genus Brachypalpus Macquart, 1834. Among European species of the genus Criorhina Meigen, 1822, it is most similar to C. asilica (Fallén, 1816), C. brevipila Loew, 1871, and C. floccosa (Meigen, 1822), all mimicking bees. Criorhina pachymera can be distinguished from C. floccosa by the hairy katepimeron (in C. floccosa, katepimeron is bare). C. pachymera clearly differs from C. asilica and C. brevipila by hind femur thickened, <5 × as long as their maximum width (fig. 45) (in C. asilica and C. brevipila, hind femur slender,> 6 × as long as their maximum width).

Body shape, color and markings of T. angustistriatum male are very similar to T. bombylans (Fabricius, 1805) (figs 51 – 54), but clearly can be distinguished from it by the hind tibia black anterolaterally at least third of the length of the tibia (fig. 48) (in T. bombylans, hind tibia without black mark anterolaterally, or with black mark occupying no more than one sixth of the length of the tibia, as on fig. 52) (Speight & Sarthou, 2017). Additionally, T. angustistriatum male can be distinguished from T. bombylans by: mid tibia yellow with blackish incomplete ring (mostly expressed on the posterior side) just below the middle of tibia not less than a third of the length of the tibia (fig. 49) (in T. bombylans, mid tibia entirely yellow, as on fig. 53), a third of the hind femur at the apex mostly with black macrotrichia (fig. 50) (in T. bombylans, a third of the hind femur at the apex mostly with pale macrotrichia, as on fig. 54).
