37330608FF9BA9226789FC2B6437F8A1.taxon	description	Description. Holotype ♂ (Fig. 1 B). Length: 1.75 mm (from antennal insertion to posterior part of epandrium). Head. Black; occiput and vertex black; eyes dichoptic separated at vertex by distance between lateral ocelli; antennae black; scape minute; pedicel cylindrical, slightly wider than long; first flagellomere ovoid, length slightly less than twice the greatest width; second flagellomere about 0.6 × as long as first, with apical style; proboscis brown, short; palpus not evident. Thorax. Scutum with a pair of yellow admedian vittae from humeral calli to prescutellar area (Fig. 1 B); lateral sclerites, prescutellar area and scutellum yellow; legs dark brown. Wing (Fig. 1 B; 2 E, F). Hyaline; Costa ends just beyond vein R 4 + 5; vein Sc incomplete, ending about where R 2 + 3 joins R 1; R 2 + 3 joins R 1 much before midpoint; R 2 + 3 arising almost perpendicularly from Rs; R 4 + 5 with a slight curve; vein M 1 slightly curved toward wing margin; M 2 fairly straight to wing margin except for slight curve in distal fifth; crossvein dm-cu closing discal cell present; line through cell dm from attachment of r-m to attachment of M 4 almost perpendicular to longitudinal axis of wing; vein A 1 present as a curved fold; sparse fringe of rather long setulae along posterior margin of wing. Abdomen. Dorsum brown or black, with a yellow fascia on posterior margin of each tergite; venter brown or yellow. Parameral sheath long, apically bifid; a straight, strongly sclerotized, parallel-sided rod (fused gonocoxae?) almost half as long as the abdomen projects ventromedially (Fig. 1 C – F).	en	Perkovsky, Evgeny E., Sun, Haoran, Perkovsky, Alisa A., Pape, Thomas (2025): Swarming microbombyliids (Diptera, Mythicomyiidae) in amber from Ukraine: a new species and a new synonymy.

37330608FF9BA9226789FC2B6437F8A1.taxon	discussion	Remarks. Mythenteles evenhuisi differs from all other species of Mythenteles by vein R 2 + 3 joining R 1 much before midpoint; and by a unique shape of wing cell dm, where a line drawn from the attachment of r-m to the attachment of M 4 is almost perpendicular to the longitudinal axis of the wing (this line is clearly slanting in other species of Mythenteles, with anterior part more proximal than posterior part, see Evenhuis 2003). Additionally, the male terminalia of M. evenhuisi feature a long, ventromedian process, here tentatively interpreted as elongated and fused gonocoxites, not observed in any other species of the genus. Mythenteles evenhuisi has the second flagellomere about 0.6 × as long as first, R 2 + 3 arising almost perpendicularly from Rs, and the abdomen with a yellow fascia on the posterior margin of each tergite; while M. baltica has the second flagellomere about 1 / 3 as long as the first, vein R 2 + 3 arising at an acute angle from Rs, and the abdominal terga all shining brown (Evenhuis 2002). Mythenteles evenhuisi is similar to M. baltica by both having a pair of yellow admedian vittae, but in M. evenhuisi the vittae reach the entire length of the scutum to fully separate the black marking into a dorsomedian part and a pair of lateral parts (some variation is apparent, and some specimens have the anterior part of vittae very narrow). The bifid parameral tip is shared with M. baltica. The length of M. evenhuisi is 1.6 – 2.0 mm vs. 0.98 – 1.06 mm indicated for M. baltica (Evenhuis 2002), but this is partly an artefact from difficulties in measuring, and the two species are probably about the same size (Evenhuis pers. comm. 2023).	en	Perkovsky, Evgeny E., Sun, Haoran, Perkovsky, Alisa A., Pape, Thomas (2025): Swarming microbombyliids (Diptera, Mythicomyiidae) in amber from Ukraine: a new species and a new synonymy.

Holotype ♂ SIZK DU- 140 a [Rovno amber; examined]; Dubovka, Varash District.	en	Perkovsky, Evgeny E., Sun, Haoran, Perkovsky, Alisa A., Pape, Thomas (2025): Swarming microbombyliids (Diptera, Mythicomyiidae) in amber from Ukraine: a new species and a new synonymy. Zootaxa 5716 (2): 234-244, DOI: 10.11646/zootaxa.5716.2.3, URL: https://doi.org/10.11646/zootaxa.5716.2.3
37330608FF9FA9206789FADA64EFFDB4.taxon	discussion	Remarks. Amber inclusions of Mythicomyiidae are rather common in Dubovka and constitute 27 % of all known dipterans from this locality (Vlaskin & Perkovsky 2005; our data). The holotypes of both nominal species originated from a large piece of amber E- 97 (9.7 g) with several syninclusions (SIZK DU- 138: Mymaridae, Anaphes sp.; SIZK DU- 140: Rhagionidae, gen. sp.; SIZK DU- 141: Aphelinidae, gen. sp.) as well as wood particles and numerous stellate hairs. Evenhuis (2013: 375) indicated that the sample DU- 140 a (given as “ DU- 140 ”) with the holotype contains “ another Glabellula specimen unfortunately cut sagittally when the piece was originally prepared and in too deteriorated condition to make a determination ”. Still another Glabellula specimen is seen side by side with the cut one, and even a third strongly cut and undetermined specimen of Mythicomyiidae is present. In our re-examination of these pieces, we have counted a total of six better preserved specimens of Mythicomyiidae. The apical placement of the antennal style is well seen. According to our observations, no stump vein emanates from crossvein bm-cu + dm-cu into cell bm + dm. Right wing of the holotype of Glabellula perkovskyi with very short, lightly coloured fold which is not perpendicular to the edge of cell bm-dm (Evenhuis 2013: fig. 10) but runs subparallel to it. On the left wing, this fold is not touching the margin of cell bm-dm. These short folds are not visible on both wings of G. perkovskyi at the same time under any kind of lighting. These folds, unlike veins, are not visible from the wing underside. The right wing of the holotype of G. aggregata is visible in the inclusion only from the underside and only a small distal part of the left wing is visible, from underside as well. Only the left wing of one of the paratypes of G. aggregata is visible from above and in such a position that the discussed fold is barely discernible, as in the holotype of G. perkovskyi. Thus, the fold on the right wing of the holotype of G. perkovskyi is likely an artefact, and given that it was the reason to erect the second species from the same locality (both nominal species are described from the same piece of amber, but this was unknown to Evenhuis) a new synonymy is proposed: Glabellula aggregata Evenhuis, 2013 = Glabellula perkovskyi Evenhuis, 2013, syn. nov. We have chosen to give G. aggregata precedence over G. perkovskyi because the terminalia of the holotype are better seen.	en	Perkovsky, Evgeny E., Sun, Haoran, Perkovsky, Alisa A., Pape, Thomas (2025): Swarming microbombyliids (Diptera, Mythicomyiidae) in amber from Ukraine: a new species and a new synonymy.
