Pseudomyrmex villosus

Known only from the holotype worker

Identification
This species can be recognized by its large size, broad head, short eyes, and rather conspicuous (subdecumbent) pubescence. The short petiole and sublucid integument are also distinctive. (Ward 1989)

Distribution
This taxon was described from Brazil.

diagnosis. A large species (for the P. subtilissimus group) with broad head and relatively short eyes. Sides of head broadly convex, rounding into the distinctly concave occipital margin. Fore femur broad; metanotal groove rather shallow; basal face of propodeum slightly convex (lateral view), rounding into the much shorter declivitous face. Petiole relatively short and high, with a distinct anteroventral tooth; postpetiole broader than long.

Mandibles striato-punctate, subopaque. Head densely punctulate, sublucid, with shiny interspaces between the fine, partially effaced punctulae. Remainder of body punctulate to coriarious-imbricate, largely sublucid. Erect pilosity sparse, distributed as in Pseudomyrmex spiculus (q.v.). Pubescence common on most of body, many hairs decumbent to suberect, and thus more conspicuous than in other members of the P. subtilissimus group. Body brown, mandibles, tarsi, petiole, postpetiole, and (to a lesser extent) pronotum and antennae lighter (luteous-brown) in color.
