B61887F23213300DD18EB625773FFB35.taxon	diagnosis	Diagnosis. Taken as a whole, the new species is consistent with the group of species placed in the subgenus Truncevylaeus by Pesenko (2007 a: 24) [i. e. L. clypeiferellum (Strand, 1909), L. corvinum (Morawitz, 1877), L. puncticolle (Morawitz, 1872), L. resplendens (Morawitz, 1889), L. truncaticolle (Morawitz, 1877), L. schachti (Warncke, 1984) L. villosulum (Kirby, 1802), L. medinai (Vachal, 1895), L. berberum (Benoist, 1941); the last two species were restored from synonymy of L. villosulum by Pauly et al. 2019]. In rugulose structure of mesepisternum (at least on upper half) the new species is similar to species of L. villosulum - complex and L. clypeiferellum. In the sculpture of mesoscutum (relatively dense punctuation, delicately shagreened surface at least on anterior half) L. ekaterinae sp. nov. is similar to that of L. medinai. The new species is closest to L. puncticolle in structure of the propodeum with very coarse wrinkles on the dorsal surface, including lateral angles, the dorsal surface forming a distinct right angel with the posterior vertical surface along all posterior margin. L. ciscaspum from the L. pauperatum species group also has similar structure of propodeum, but from this species L. ekaterinae sp. nov. differs by larger body size.	en	Astafurova, Yulia V., Proshchalykin, Maxim Yu.

Head (Fig. 1) transverse-elliptic, 1.14 times as wide as long; vertex not elevated, distance from top of head to upper margin of lateral ocellus ca. half lateral ocellar diameter as seen in frontal view. Clypeus 2.1 times wider than high; on lower half with coarse puncture and distinct shiny and smooth interspaces, on upper half with tiny punctures separated by less than one puncture diameter. Supraclypeal area dull, with tiny and confluent punctures. Paraocular area dense punctate, distinctly shagreened lower antennal socket and smother along eyes. Frons confluently punctate. Ocello-ocular area shiny and smooth with tiny (5 μm) relatively sparse punctures. Vertex behind ocelli delicately shagreened with hardly visible sparse punctures. Genal area expanded downward, delicately transversely rugose, smooth and tiny punctate along eyes (Fig. 2). Mesoscutum delicately shagreened, smoother to posterior margin, relatively dense punctate (10 – 15 μm / 1 – 3), sparser medially (Fig. 8). Mesoscutellum shiny and smooth, tiny (ca 10 μm) and irregularly and punctate. Inner metatibial spur with several short triangular teeth (Fig. 4). Mesepisternum rugulose, smother to posterior margin (Figs 5, 6). Propodeum (Fig. 3) short, its dorsal surface trapezoidal, as 0.7 time as long as scutellum, flat, horizontal, shiny with very coarse wrinkles, including lateral angles; lateral surface densely shagreened; posterior vertical surface densely shagreened with sparse coarse wrinkles, forming distinct right angel with vertical and lateral surfaces, sharply carinate along lateral margins. Terga (Fig. 7) shiny and smooth, with tiny punctures (ca 5 μm); T 1 sparsely punctate, almost impunctate on vertical surface and along marginal zone, marginal zone T 1 smooth and impunctate; other terga denser punctate with delicately transversely lineolate marginal zones. Sterna tessellate. Coloration. Body black; last flagellomeres on lower side brownish; wings slightly brownish infuscated, veins and stigma dark brown; marginal zones dark, not translucent, slightly lighter along posterior margin. Pubescence. Dirty whitish, on legs pale-yellowish, on head and mesosoma with relatively sparse (integument well visible), erect, relatively long setae. Terga with sparse and short setae, laterally with long erect setae; pygidial fimbria golden. Sterna with long erect setae along posterior margins. Male unknown.	en	Astafurova, Yulia V., Proshchalykin, Maxim Yu. (2025): Review of the bee genus Lasioglossum Curtis, 1833 (Hymenoptera: Halictidae) fauna of the Ciscaucasia region.

B61887F2320C3010D18EB42270F5FD10.taxon	discussion	Remarks. Blüthgen (1931: 348) described Lasioglossum haesitans from a male and suggested the possible synonymy of this species with L. korbi (Blüthgen, 1929) because of the more likely association of the male of L. haesitans with female of L. korbi. Later L. haesitans was considered as a junior synonym of L. korbi (Pesenko 1986; Astafurova & Proshchalykin 2017 a, 2018). Ebmer (2014: 347) restored L. haesitans as a valid species. Ebmer does not give a diagnosis or description of the female, but noted on misidentification with L. quadrinotatum in published data. A female of L. haesitans from Greece was illustrated in Pauly (2016). The correct identification of the species can only be done by the male, which differs from L. quadrinotatum by entirely black clypeus or only narrowly apical strip (vs wide yellow spot in L. quadrinotatum) and longer gonostylus, distinctly longer than wide (Fig. 9, vs about as long as wide in L. quadrinotatum, Fig. 10). The records of Lasioglossum korbi in Azerbaijan by Pesenko (1986) and Astafurova et al. (2024 a) refer to L. haesitans. Thus, L. korbi is known only from Turkey.	en	Astafurova, Yulia V., Proshchalykin, Maxim Yu.

The females of this species show significant variability in coloration of pubescence (from snow-white to yellowish), sculpture of T 1 (from tessellate and dull with dense punctures to polished and smooth with sparse punctures) and density punctures of the mesoscutum. Pesenko (2006: 154) synonymized L. tadschicum (Blüthgen, 1929) with L. leucozonium. Forma “ L. tadschicum ” differs from the typical form by white pubescence of the head and mesosoma (greyish yellow in typical form) and sparser punctation of the mesoscutum and T 1 in the female. This species occurs in forest, steppe and agricultural landscapes, but forma “ L. tadschicum ” usually occurs in desert and semi-desert plane areas.	en	Astafurova, Yulia V., Proshchalykin, Maxim Yu.

B61887F232063026D18EB781756CFCC9.taxon	discussion	Remarks. In steppe and forest landscapes. Taxonomical note. Two subspecies of Lasioglossum laticeps are known from the Caucasus: the nominate subspecies occurs in the North Caucasus and the subspecies hellenicus (Blüthgen, 1938) is known from the Transcaucasus. The status of L. debilior (Pérez, 1910) is unclear. The male of L. debilior is unknown [the male described by Ebmer (1972) as L. debilior actually belongs to L. pseudosphecodimorphum (Blüthgen 1923), see Ebmer 1995]. According to Ebmer (2014: 323), L. debilior (Pérez, 1910) is probably a senior synonym of L. laticeps ssp. hellenicus (Blüthgen, 1938). A. Pauly (2016), who re-examined the type, noted that the type specimens appear to be suitable. We support this opinion and consider that L. debilior is most likely a synonym of L. laticeps ssp. hellenicus. Future studies using integrated taxonomic techniques are needed to clarify the species boundaries of L. debilior and resolve these doubts.	en	Astafurova, Yulia V., Proshchalykin, Maxim Yu.
