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.

Biology

Espadaler (2007) - Three colonies from this Canarian endemic were collected: two were nesting under mosses on a stone; the third was nesting under a small stone. The morphology and coloration of workers and queens fits the description of T. gracilicornis, not of the darker and shinier var. nivarianus, that Wellenius (1955) collected at Frontera. As I have not seen type material of both taxa and samples from Tenerife show varying coloration—from yellow to brownish, thus including both names—and body surface shininess, I refer the samples of El Hierro to the nominal species. This is not a formal proposal of synonymy.
