Oxycheila

Overview

*Oxycheila* Dejean, 1825 is a robust, metallic Neotropical tiger beetle genus of approximately 52 species, haunting moist riparian banks and humid forest floors across South America. Nocturnal pursuit hunters, adults shelter near clay-loam substrates where larvae excavate vertical burrows. Males bear strikingly elongated mandibles, a sexually dimorphic feature linked to copulatory grasping behavior.

Type species: Cicindela tristis Fabricius, 1775 [by subsequent designation (Dejean 1825)]
