Genus
Cheiloxya
2 species
*Cheiloxya* is a small Neotropical genus of two metallic tiger beetles patrolling moist riparian banks and forest-floor substrates across South America. These nocturnal hunters, clad in metallic coloration with pale spots, favor moist clay-loam margins where their larvae excavate vertical burrows. With elongate labrum and the powerful mandibles characteristic of Oxycheilini, *Cheiloxya* is a specialist of wet, open habitats along South American waterways.
Diagnosis
DIAGNOSIS — *Cheiloxya* Guérin-Méneville, 1855. Body small, 13–17 mm, oval (L:W < 2.0). Coloration metallic with pale spots. Wings fully developed. Eyes medium. Labrum elongate, acute (etymology reflects this). Mandibles elongate, characteristic of Oxycheilini. Nocturnal; substrate moist clay-loam, riparian and forest-floor; larvae in vertical clay burrows. Two species. Synapomorphies G03=1, G04=2/3 shared with Oxycheilini. No confusion genera recorded.
Etymology
From Greek *χεῖλος* (lip) + *oxýs* (sharp) — referring to acute labrum.
