Genus
Cosmodela
17 species
*Cosmodela* Rivalier, 1961 is a genus of medium-sized, brilliantly metallic tiger beetles found across the Indian subcontinent, mainland Southeast Asia, southern China, and the Sundaland archipelago. These nocturnal hunters patrol the clay-loam and sandy banks of streams and rivers, their robust bodies glinting under moonlight. With roughly fifteen species, *Cosmodela* represents one of the most visually striking elements of Oriental riparian beetle fauna.
