Synonyms

Consistently collected and observed on trees, this species is an arboreal nester. Longino found a nest inside a large, deep knothole and records prey items of the following: Heteroptera: Pentatomidae, Aradidae; Coleoptera: Cerambycidae, Histeridae, Platypodidae, Chrysomelidae, Tenebrionidae, and Passalidae. One observed foraging group was made up of 9 workers and a dealate queen. Observations of group foraging of up to 40 single-file workers, plus the following Longino observation, indicate trail and/or recruiting pheromone communication in this species. “The foragers walked with their gasters curled and touching the substrate. When they were together near the prey I could often make out a tiny white area (gland?) exposed at the very tip of the gaster, which other workers would investigate”. (Lattke 1995)

Identification

A member of the concinna species group. A large finely striate species with transverse striae on propodeum, declivity medianly smooth; Promesonotal suture weakly impressed or absent; mesometanotal suture deep and wide; metacoxal tooth absent, low crest or tubercle at most. Color can vary from ferruginous to light-brown, and the striae on the posterior nodal face may be effaced. (Lattke 1995)
