Nests of L. uzbeki have been found under stones in two habitats: open grassy areas with bushes and alluvial sites with trees or bushes.
Identification
Seifert (2020) - The combination of very large eyes, rather short terminal segment of the maxillary palps, and long gular setae are not found in any other Palaearctic species of Lasius.

Description
Worker
Seifert (2020) - Absolute size rather small (CS 861 µm). Scape long but terminal segment of maxillary palp rather short (SL/CS900 0.994, MP6/CS900 0.172). Postocular distance very small (PoOc/CL900 0.219). Eye very large (EYE/CS900 0.264), even larger than in species related to Lasius emarginatus. Number of mandibular dents medium (MaDe900 8.14). Pubescence on clypeus dilute (sqPDCL900 5.01) but on postocular head sides and frons much denser than in Lasius schulzi. Setae on dorsum of scape and extensor profile of hind tibia thin and often difficult to distinguish from semierect pubescence which causes high variance in setae counts. Pronotal setae long (PnHL/CS900 0.163). Setae on underside of head very long and numerous (GuHL/CS900 0.132, nGu900 6.7). Coloration: polymorphous; the light morph, as represented by the type sample, has a light yellowish mesosoma with a brownish tinge, a pale yellowish-brown head, and a slightly darker gaster; the dark morph, as represented by the majority of samples, typically shows a dirty brown mesosoma with a yellowish component, a dark brown head, and blackish brown gaster.
See table 5 in Seifert 2020 for additional morphometrics. The abbreviated names of various quantitative data shown above are defined here: Seifert 2020 Lasius characters.
