Specimen Label

Known from a few collections this ant has been found in rainforests. Most samples are from litter samples with the exception of a collection from the base of a tree. Nothing else is known of its biology.


The only member of the genus. The worker is similar to Bothriomyrmex in having a broadly convex anterior clypeal margin, elongate anterior clypeal setae, an anteriorly-placed posterior clypeal margin, relatively small compound eyes, and in the overall shapes of the mesosomal profile, petiole and first gastral segment. However, Loweriella differs from Bothriomyrmex in having well developed frontal carina; the medial hypostoma notched rather than completely absent; the mandible with a greater number of teeth, a relatively larger apical tooth and a more poorly defined basal mandibular angle; a 6:4 palp formula; and having a keel-shaped fourth gastral sternite. These differences allow ready separation of Loweriella and Bothriomyrmex and suggest that each is distinct from the other.


Known only from northwestern Borneo (northern Sarawak, Malaysia and Brunei).
