Boltonia Camacho and Feitosa new genus

Type Species: Boltonia microps (Borgmeier) new combinationtion ( Fig. 3 )

Diagnosis (Females): Ants of comparatively small size (head width 0.42-0.53, head length 0.53-0.67). Mandible subfalcate. Palp formula 3,2. Frontal lobe expanded, completely covering antennal insertions. Antennal club with three antennomeres. Antennal scrobe absent. Eye drastically reduced, without conspicuous limits between ommatidia. Propodeum unarmed. Tarsal claw simple, without conspicuous preapical teeth nor a basal lobe. Petiole unarmed. Anterior face of abdominal segment III without an arched carina above the helcium.

Species: microps .

Distribution: Exclusively Neotropical, from Costa Rica to northern Argentina and southern Brazil.

Notes: We here propose the new genus Boltonia to accommodate a single species, B. microps ( Borgmeier 1957) , formerly a member of Heteroponera . This species represents a divergent lineage at the base of Heteroponerini and is the sister-group of all the remaining species in the tribe. The genus name is an homage to Barry Bolton, legendary ant taxonomist and author of Bolton’s Catalogue of Ants of the World, which is the very foundation of all taxonomic papers published in myrmecology since 1994.
