Lasius turcicus species complex

Mean number of mandibular dents low (MaDe 900 7.3– 7.7). Petiole scale in lateral view thin and forming an acute tip; its dorsal crest in anterior view straight or slightly emarginate. Clypeal pubescence dilute (sqPDCL 900 5.1– 5.5). Mean length of pubescence hairs on frons larger (PLF 900 30–38 µm). Dorsum of scape without or with only very few setae. Setae numbers on head and mesosoma larger than in the L. brunneus complex (nOcc 900 + nGu 900 + nSt 900 11.8–29). Six species: Lasius turcicus Santschi 1921, Lasius neglectus Van Loon et al. 1990, Lasius austriacus Schlick-Steiner 2003, Lasius tapinomoides Salata & Borowiec 2018, Lasius precursor sp. nov. and Lasius israelicus sp. nov.
