Platycheirus aurolateralis Stubbs, 2002 View in CoL ( Fig. 2–4)

Material examined. Russia: Moscow Region, Tabolovo , 55.915N 36.049E, in the grass, 27– 30.07.2018, 4 ♂ ( A. Prokhorov) GoogleMaps .

Distribution. Ireland, Great Britain, Nederland, Norway, Sweden, eastwards through Germany to the Alps ( Austria, France, Switzerland, Italy) and on to Slovenia, Czech Republic (on the border with Poland) and Turkey ( Doczkal et al., 2002; Smit, 2003; Speight, 2017); Russia (first record).

Diagnosis. Platycheirus aurolateralis belongs to the P. scutatus complex within the P. albimanus species group (Young et al., 2016), which is recognized by the following characters: the male second fore tarsomere length is less than ¼ of the basotarsomere; a finger-like process on the anterior edge of the male mid coxa; male (also female but less distinct) with a small projection on trochanter 1 apicoventrally bearing a hair tuft; male and female katepisternum with hairs on the lower patch being much shorter than those of the upper patch ( Doczkal et al., 2002).

Male: differs from P. scutatus by the frons covered by dark erect microtrichia, strongly contrasted with facial pollinosity ( Fig. 3) (in P. scutatus , the frons densely covered with light grayish or yellowish adpressed microtrichia not contrasting with facial pollinosity); facial hairs mainly dark (in P. scutatus , facial hairs mainly pale); tergite 2 often lacking paired spots or with small yellow spots ( Fig. 2 A) (in P. scutatus , tergite 2 always with two large paired yellow spots); the black area between the spots on tergite 3 is about as long as wide or shorter than wide (as on Fig. 2 A) (in P. scutatus , the black area between the spots on tergite 3 is about 1.5–2 times as long as wide) ( Doczkal et al., 2002; Bartsh et al., 2009).

From similar P. speighti it differs by only slightly swollen mid tibia (as on Fig. 4) (in P. speighti , mid tibia strongly swollen); the apical part of the mid tibia bent downward at an angle of about 20° (in P. speighti , the apical part of the mid tibia bent downward at an angle of about 30°); trochanter 1 apicoventrally right-angled (in P. speighti , trochanter 1 apicoventrally pointed); fore tibia with a submedian dark spot of more or less rectangular shape (in P. speighti , fore tibia with a submedian dark spot of more or less triangular shape) ( Doczkal et al., 2002).

From most similar P. splendidus it differs by mid tibia ventrally with rather long, silvery white hairs ( Fig. 4 B) almost as long as tibia width (in P. splendidus , mid tibia ventrally with sparse and short hairs); the anterodorsal side of the mid tibia at the base with distinctly long black hairs, its length exceeding the thickness of the tibia ( Fig. 4 A) (in P. splendidus , the anterodorsal side of the mid tibia at the base with few relatively short hairs); entire posterodorsal side of the mid tibia with long black hairs ( Fig. 4 A) (in P. splendidus , posterodorsal side of the mid tibia with two groups of long hairs); tergite 2 often without paired sports (in P. splendidus , tergite 2 always with paired sports) ( Doczkal et al., 2002; Bartsh et al., 2009).
