4.4.13 Lasius psammophilus Seifert 1992 Lasius psammophilus Seifert 1992 [type investigation] Type material: Holotype plus 4 paratype workers labelled “GER: Kr. Weisswasser 4 km N Steinbach: N 135 30.7.1991, leg. Seifert“; 26 paratype workers from the same locality and date labelling but with nest 082, sample numbers N 005, N 023, N 027, N 029, N 048, N N 206, N 215; depository SMN Görlitz. All material examined . A total of 150 nest samples with 528 workers were subject to NUMOBAT investigation. These originated from Belgium (1 sample), Georgia (1), Czechia (3), Denmark (5), England (3), Finland (2), France (10), Germany (86), Greece (7), Italy (14), Norway (2), Slovenia (1), Spain (1), Sweden (7), Switzerland (4), Turkey (3). For details see supplementary information S1. Geographic range . European, temperate-submeridional. From British Isles and France across Central and East Europe. Rapid postglacial immigration into North Central Europe via sand dunes and the outwash plains of big ancient river valleys is highly probable. In Central Europe and S Fennoscandia most abundant in sandy regions of the planar and colline zone but penetrating also mountain areas along river valleys: in the S Schwarzwald ascending to 1000 m and in the Alps to 2030 m (in S Tyrol at 46.5°N). Competing with L. paralienus in the High Apennine grasslands. Absent from Iberia and probably also the S Balkans, in N Greece at 40°N between 1600 and 1900 m. Main border of northern distribution in Sweden and Finland at 63.5°N but ranging north to 65.8° along the shores of the Gulf of Bothnia. Sympatric occurrence with Lasius obscuratus in Asia Minor and Great Caucasus, here easternmost known site at 52.52°N, 44.94°E. Sympatric occurrence with L. piliferus occurs in the Pyrenees. Diagnosis (Tab. 3, Figs. 25 –26; key; images in www. antWeb.org with specimen identifiers CASENT0172733, CASENT0179885, FOCOL0752): Absolute size rather small (CS 826 µm). Scape and head length indices and number of mandibular dents medium (SL/CS 900 0.960, CL/CW 900 ...
