Specimen labels


Unlike congeneric species with subterranean nests, T. rogenhoferi nests exclusively inside stumps of dead wood (Lacau et al. 2008). They occur throughout Central and South America between 30°S et 20°N, a much broader distribution than other congeneric species (Brown, 1964; Lacau et al., 2004).

Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.

Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.


Sébastien Lacau studied many colonies over 11 years in French Guyana and Brazil (Para and Bahia States). Workers of T. rogenhoferi are the largest in this genus and show striking variation (2X) in body size. Colonies frequently exceed 2000 workers, which is atypical for Ectatomminae. This species is a highly opportunistic hunter inside dead stumps, and there is no cooperation during foraging. Larvae of Lampyridae (Coleoptera) live peacefully inside the nests of T. rogenhoferi, and there is no predation of ant brood or adults (Lacau et al. 2008). Workers were observed to lick the lampyrid larvae, possibly due to an attractive secretion.

Lacau et al. (2008) provided a detailed description of the sting apparatus

De la Mora et al. (2016) found this species nesting in logs found in coffee farms in the Soconusco region of Chiapas, Mexico.
