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.
