This species is known only from a short type series that lacks biological data on its labels (Borowiec and Salata 2022).
Identification
Borowiec and Salata (2022) - Lasius karpinisi is difficult to identify as it lacks unambiguous identification characters. It is distinguished from other species with antennal scapi lacking erected setae and dense pubescence of clypeus by a combination of characters: elongate scape (Sl/HL 0.998-1.014), head broad with shallowly concave occipital margin, well developed clypeal carina and mesosoma reddish brown. Only Lasius illyricus have similar combination of characters but differs in antennal scapi with at least partly erect or semierect hair or setae and usually with more than 4 erected setae on hind tibiae.

Description
Worker
Head: single 25-35° genal setae may be present; occipital hairs distributed frontad to eye. Clypeal carina clearly developed, lateral profile convex. Mandibles with 8, in one specimen with 9 teeth. Head broad, with slightly concave occiput; scape long, HL/HW (900) 1.045, SLIHL (900) 1.009. Mesosoma: rather compact, mesopropodeal depression deep, propodeal dome rather hemispheric, posterior slope of propodeum rather straight. Scale: sides weakly convex, only slightly converging dorsad (almost parallel); dorsal crest slightly emarginate; in lateral view with slightly convex frontal and straight posterior profile. Scape: pubescence smooth, 0-20°, setae on dorsal plane completely absent. Hind tibia: pubescence surface smooth, 5-10°; few setae (25-65°, max. 49 /lm) present. Surface characters: frontal head weakly shining, with clearly visible microreticulum but shallow micropunctures (2-4 /lm diameter, 11-14 /lm central distance) at base of pubescence hairs and with a rather dense, smooth pubescence (l0°, PLF 26-39 /lill). Frontal pronotum with weak microreticulum. Colour: Head and gaster dark brown with reddish tinge; mesosoma, petiole, coxae and femora reddish brown; scape and tibiae reddish-yellowish; distal half of funiculus blackish brown. Data of 4 workers: HL 926.0 ± 41.9, HL/HW 1.0398 ± 0.0229, SL/HL 1.0058 ± 0.0117, CLCA 0.80 ± 0.04, PDCL 16.12 ± 2.67, nHS 0.0, nHHT 3.75 ± 2.50, nBH 9.50 ± 2.04, nUH 2.50 ± 0.58, UHL/HL 0.0917 ± 0.0040, PNHL/HL 0.1005 ± 0.0210.
Seifert (2020) - Absolute size rather large (CS 912 µm). Scape length index large (SL/CS900 1.024) but head length index, in contrast, very small (CL/CW900 1.037). Terminal segment of maxillary palps moderately long (MP6/CS900 0.177). Number of mandibular dents medium (MaDe900 8.30). Clypeal pubescence moderately dense, intermediate between the situation in the Lasius paralienus and Lasius obscuratus species complexes (sqPDCL900 4.18). Pronotal setae very short (PnHL/CS900 0.108). Setae number on hind margin of head moderate (nOcc900 8.0). Gular setae few (nGu900 2.6). Dorsum of scape without and extensor profile of hind tibia with few semierect setae (nSc900 0.0, nHT900 4.2). Metapleuron below propodeal spiracle with few setae (nSt900 3.5). Coloration: Head and gaster medium brown with a reddish tinge; mesosoma, coxae and femora reddish brown; scape and tibiae reddish-yellowish, distal half of antennal funiculus darker.

Borowiec and Salata (2022) - Large, HL 0.899-0.916 (mean 0.928), HW 0.850-0.977 (mean 0.897). Scape elongate, SL 0.897-0.993 (mean 0.932). Color. Head and gaster medium with a reddish tinge, mesosoma, coxae and femora reddish brown, scape and tibiae reddish yellow, distal half of antennal funicle darker than basal part. Structure and setation. Head almost as long as wide, with convex sides and shallowly concave posterior margin. Terminal segment of maxillary palpi moderately long with length of sixth segment 0.155-0.168 (mean 0.160). Occipital part of head with 12-16 erected setae. Gena with up to two erected setae, underside of head with 1-3 erected setae. Mesosomal dorsum with rather short erected setae (length of the longest seta 0.078-0.121, mean 0.099). Below propodeal spiracle 0-3 erected setae. Masticatory border of mandibles with 8-9 teeth. Antennal scapi with smooth pubescence lacking erected setae. Hind tibiae on external surface in basal parts without or with 1-4 erected setae. Pubescence on the whole body and appendages dense and whitish. Pubescence of clypeus dense, clypeus well visible. Surface of gastral tergites distinctly sculptured , first gastral tergite in central part with numerous erected setae. Propodeum in lateral view conical, metanotal groove deep.
