Description

Worker

Holotype: TL 7.5; HL 2.28; HW 2.28; EL/HW 0.19.

Head shining, dark red, contrasting with dark alitrunk and gaster. Whole of alitrunk dorsum finely transversely striate. Petiole dorsum sculptured; postpetiole and gaster smooth and shining with some superficial sculpture. The propodeal profile is steeply rounded but not angulate; the petiole is a rounded triangle and the postpetiole is simple, without a distinct anteroventral projection as seen in profile and very slightly longer than broad in dorsal view. The alitrunk has several hairs, the petiole and postpetiole each have two pairs and the first gaster tergite has seven visible in full profile. This species differs from Messor semirufus in the much darker body colour, slightly larger eyes and the longer lower postpetiole. The ants were taken from a large populous nest in a sun-exposed sheltered part of the high pass.
