Temnothorax angulinodis

Nothing is known about the biology of .

Identification
Csösz et al. (2015) - A member of the angulinodis species-complex. Due to the unique combination of the long spine, high petiole, and sharp transversal crest on the dorsum of the petiolar node this species is easily distinguishable from related taxa even by simple visual inspection.

Distribution
This species is known only from the Peloponnese peninsula.

Distribution based on Regional Taxon Lists
Palaearctic Region: Greece.
