Synonyms

This species nests under stones, and is a guest in the nests of Myrmica fracticornis and Myrmica incompleta. Apparently it cannot live without its host in the laboratory, although it can be found nesting alone in the field. Sexuals occur in the nests in July and August. (Mackay and Mackay 2002)

At a Glance • Xenobiotic  

Identification

This species has several erect hairs on the eyes, and the clypeus of the worker is weakly depressed in the middle and is without a medial carina, although several lateral carinae are present. The scapes have numerous suberect hairs. The propodeal spines are well developed, and thickened throughout. The anterior face of the petiole meets the dorsum in a sharp angle, the posterior face is also straight. The dorsum of the postpetiole is nearly completely free of sculpture. The mesosoma has heavy and dense sculpture, con-sisting of punctures interspersed among poorly defined striae. (Mackay and Mackay 2002)
