Genus
Oxygoniola
1 species
On leaf-littered trails in Neotropical forest, *Oxygoniola* is a small, metallic tiger beetle of Amazonian shadows. Representing a compact, oval-bodied lineage allied to *Oxygonia*, it inhabits forest floors across Brazil, Colombia, and Peru. Nocturnal and rarely encountered, this diminutive genus rewards patient observers in the wet-season night.
Diagnosis
