Synonyms

Casevitz-Weulersse (1990a) calculated after an ecological survey from 234 samples in 189 localities, that A. spinosa is one of the most common epigeic ant species on the island of Corsica (France). The species is dominant in nearly every habitat, especially at altitudes below 400 m, but is also present above 1200 m. (Boer, 2013)

Identification

A member of the A. testaceopilosa group. Boer (2013) - The worker of Aphaenogaster semipolita resemble A. spinosa because of their body shine, but the two can easily be separated by the characters given in the key. These species are allopatric. Aphaenogaster spinosa most resembles Aphaenogaster iberica, especially because of the sturdy propodeal spines. Both species differ in the ratio between the SI and the CI. In both species, the degree of shiny parts varies greatly. For gynes and males see A. iberica.

Keys including this Species

Distribution

Although this species is commonly collected, its distribution area is restricted to central Italy, along the Tyrrhenian Sea, Sardinia and Corsica (Rigato & Toni, 2011).

Distribution based on Regional Taxon Lists

Palaearctic Region: France (type locality), Italy (type locality), Switzerland.
