134E05500C09FFE3FF13FBEDFC2DFB3E.taxon	diagnosis	Diagnosis. Species of the E. tarsalis species group differ from other species groups by the peculiar shape of the elevated supraclypeal area between antennal sockets, where the frontal carina is more or less enlarged laterally in lobes (Figs 1 – 3). The development of these lobes is different among species of the group: from partially covering insertion of the antennae to not reaching the edges of the antennal sockets.	en	Astafurova, Yulia V., Proshchalykin, Maxim Yu.

134E05500C0AFFE6FF13F9DCFE0DFE6E.taxon	description	Variation. The females of this species exhibit considerable intraspecific variation in integument coloration and degree of development of the tergal tomentum spots. According to the description (Yasumatsu 1938), the redescription (van Lith 1956) and additional illustrations (Mitai 2014) the Japanese female specimens are mostly black. Unlike these black forms, the continental specimens from Russia and Mongolia possess redder body coloration. All female specimens examined from these territories have entirely or partially red axilla, mesoscutellum, pronotum and mesepisternum (Figs 9, 11), sometimes red patterns can be developed on the mesoscutum (along lateral margins and a pair of spots near posterior margin). The red pattern of mesepisternum varies from a small spot (rare) on upper half to entirely red integument (usually). Two examined females from China (Inner Mongolia) are close to the black Japanese form. The males are black and not variable in coloration. There is some variation in the size of tergal tomentum spots and bands. In the females, T 2 lateral fascia (Fig. 11) is often reduced to two lateral spots (Fig. 9), and two lateral spots on T 3 and T 4 are reduced to one small spot (Fig. 9). Among the male specimens we have not found any reduction of the T 2 lateral fascia, but lateral fasciae on T 3 and T 4 are usually reduced to just spots and only a few specimens have complete lateral fasciae on these terga.	en	Astafurova, Yulia V., Proshchalykin, Maxim Yu.

134E05500C0EFFE4FF13FF55FD8FF87B.taxon	description	Variation. The female of this species exhibits a considerable intraspecific variation in punctation of vertex, ocelloocular area and hind femora, degree of development of tergal tomentum spots, and coloration of mesoscutellum and axillae (Pittoni 1947; van Lith 1956). In our materials from Siberia and Russian Far East, females exhibit almost no variation in coloration, most of species have entirely red mandibles, labrum, tegulae, axilla and mesoscutellum, pronotal lobe and legs (except of dark spurs and partially brownish coxae) (Figs 8, 10), a few specimens with red apical margin of clypeus, black labrum, axilla and partially black pronotal lobes. In terms of integument coloration, examined specimens correspond to the description of female of Epeolus tarsalis himukanus by Mitai & Tadauchi (2009), except in having a black hypoepimeral area. Lateral fascia on T 2 is complete (not reduced on to lateral spots), but the paired lateral spots on T 3 vary in size or rarely are reduced to one spot (Fig, 10). The punctation of the ocello-ocular area slightly varies from entirely confluent to with interspaces ca a half puncture diameter. The punctation of hind femora on anterior surface varies from mostly confluent (Fig. 4) to punctures separated by 1 – 2 puncture diameters (Fig. 5). In the males lateral fasciae of T 3 and T 4 are often narrow medially (Fig. 6) and sometimes reduced to paired spots (Fig. 7).	en	Astafurova, Yulia V., Proshchalykin, Maxim Yu.

Bischoff (1930), Pittioni (1947), and van Lith (1956) considered this name as valid. However, van Lith (1956) noted that E. sibiricus is presumably not more than a subspecies of E. tarsalis. Quest (2009) listed E. sibiricus as a valid species and recorded it from Primorskiy Territory based on several specimens determined by M. Schwarz (Ansfelden, Austria). Warncke in his notes (unpublished, P. Bogusch, personal communication) suggested the synonymy of E. sibiricus with E. tarsalis. Bogusch and Hadrava (2018) listed E. sibiricus as a synonym of E. tarsalis, but without comments and indicated that types were not examined. In the “ Annotated Catalogue of the Hymenoptera of Russia ” (Levchenko et al. 2017) this name was omitted. The re-examination of syntypes is required to clarify this synonymy and until this action we treat E. sibiricus as a possible synonym of E. tarsalis. The type materials of E. sibiricus were deposited in Museum für Naturkunde, Berlin (Germany), but they were borrowed by F. Gusenleitner in 1998 and probably are still in Oberösterreichisches Landesmuseum, Biologiezentrum, Linz (Austria). According to Pittoni (1947) E. sibiricus differs from E. tarsalis by the red pronotal lobe in males, the entirely red mesepisternum in females and the reduction lateral fasciae on T 2 and T 3. Among specimens of E. tarsalis examined by us from Siberia and Far East, there are no males with red pronotal lobes and there are no females with red mesepisternum. Also, there are no females with lateral fascia on T 2 reduced to two spots as in E. sibiricus. It should be noted that such red coloration of the mesepisternum and reduction of the tergal lateral fascia are typical for female specimens of E. melectiformis collected in the Primorsky Territory (Figs 9, 11), and which are relatively common there. So, the female syntype (s) of E. sibiricus may belong to E. melectiformis. However, the male of E. tarsalis (? = sibiricus) is well distinguished from E. melectiformis by lacking long setae just before the posterior margin of the last sterna. This important feature was mentioned by Pittoni (1947) in diagnosis of the E. tarsalis species group, so the male syntype (s) of E. sibiricus cannot be E. melectiformis. Quest (2009) recorded several specimens of E. sibiricus in the Lazovsky Nature Reserve (Primorsky Territory), but did not list E. tarsalis and E. melectiformis. In our material, we only have a male from the Lazovsky Nature Reserve belonging to E. tarsalis.	en	Astafurova, Yulia V., Proshchalykin, Maxim Yu.
