Identification

Yellowish with the head often brown and the gaster characteristically having a dark band across the first gaster segment. The propodeal spines are short but strong and distinct. The outline of the alitrunk is more flattened than in L. interruptus and the petiole node in the worker has a distinct dorsal truncate area which meets the anterior face at a clearly defined angle. Length: 2.8-3.5 mm (Collingwood 1979).

Distribution

An abundant species throughout Central and South Europe from Spain, Kazakhstan, Turkmenistan, Switzerland to the Caucasus and from South Italy to North Germany and the Netherlands (Collingwood 1979).

Distribution based on Regional Taxon Lists

Palaearctic Region: Albania, Andorra, Armenia, Austria, Belarus, Belgium, Bulgaria, Channel Islands, Croatia, Czech Republic, Denmark, France (type locality), Georgia, Germany, Greece, Hungary, Iberian Peninsula, Israel, Italy, Jersey, Kazakhstan, Liechtenstein, Lithuania, Luxembourg, Malta, Montenegro, Morocco, Netherlands, Poland, Portugal, Republic of Macedonia, Republic of Moldova, Romania, Russian Federation, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, Turkmenistan, Ukraine, United Kingdom of Great Britain and Northern Ireland.

Biology

Collingwood (1979) - This widely distributed and common species is rather similar to Temnothorax tuberum but is slightly larger and in the female castes easily distinguished by the banded gaster. It nests among rocks and under stones but also frequently occurs under bark. Individual colonies are usually more populous than the other North European Leptothorax species with workers numbering 200 or more. Alatae are found in July and August.

Fungi

This species is a host for the fungus Myrmicinosporidium durum (a pathogen) (Espadaler & Santamaria, 2012).

Taxonomic Notes

Plateaux, L. & Cagniant, H. 2012: 436: We conclude from all these observations that Leptothorax tuberum unifasciatointerruptus is a hybrid of Temnothorax unifasciatus and Temnothorax albipennis. Hybridization works in both directions, parents may be alternately of the two species, and males are from the parthenogenetic egg of the queen mother. Note that both species exist also in places (especially in Luberon and Ventoux) where the where the form was found. We therefore ask: T. albipennis x T. unifasciatus = L. tuberum unifasciatointerruptus Forel.
