Lasius paralienus

Guiliani et al. (2019) observed this species foraging on extrafloral nectaries of the invasive Reynoutria x bohemica (Polygonaceae) in Tuscany. The habitats examined were river banks and disturbed habitats.

Identification
Seifert and Galkowski (2016) - Palaearctic Lasius s. str. species belonging to the Lasius paralienus species complex. The species in this complex are separable from related species by the combination of low clypeal pubescence distance, low setae numbers on scape and differences in length of maxillary palp segments. Lasius alienus, Lasius psammophilus and Lasius piliferus are the most similar species occurring within the geographic range of the three L. paralienus complex species. L. alienus differs from the other five species by having strongly reduced setae numbers on the metapleuron below the level of the propodeal spiracle. A safe separation of individual workers is possible by a discriminant function considering head width, the length of the terminal maxillary palp segment and clypeal pubescence distance.

Distribution
Seifert and Galkowski (2016) - Lasius paralienus has a European, north meridional to temperate distribution. In the south it ranges from S France (0.7°W) over all of Italy east to Bosnia and Bulgaria (25°E). The main distribution in Central Europe reaches north to about 52.5°N. North of this line only isolated populations are known in Sweden: Södermanland (59.1°N), Öland (56.7°N) and Gotland (57.4°N). In Germany it ascends to 990 m (at 47.9°N) and at the southern slope of the Alps to 1800 m (at 46.8°N).

Distribution based on Regional Taxon Lists
Palaearctic Region: Andorra, Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, France, Germany, Greece, Hungary, Iberian Peninsula, Italy, Montenegro, Poland, Republic of Macedonia, Romania, Russian Federation, Slovenia, Spain, Sweden, Switzerland.
