526787B8B456357CFF13F91AFB61FB71.taxon	diagnosis	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).	en	Prokhorov, A.
