Genus
Callytron
15 species
*Callytron* Gistl, 1848 is a medium-sized tiger beetle genus of roughly eleven species distributed across a remarkable combined range spanning the Palaearctic, Oriental, and Afrotropical regions. These metallic, depressed beetles favour open wet habitats, foraging nocturnally across bare soil and mudflats from Iran and Pakistan eastward through India, Sri Lanka, and Southeast Asia to China, Japan, and the Philippines. Larvae develop in characteristic vertical burrows excavated in open substrates. With their large, protuberant eyes and flattened bodies, *Callytron* species are well-adapted hunters of poorly vegetated, often brackish or riparian terrain.
Diagnosis
DIAGNOSIS — *Callytron* Gistl, 1848 Body 10–18 mm, depressed-elongate, metallic. Head wider than pronotum; eyes very large, strongly protuberant. Pronotum subquadrate. Elytra elongate, parallel-sided; hind wings fully developed. Labrum transverse. Nocturnal; open wet habitats, bare soil; larvae in vertical burrows. Distinguished from *Cylindera* by more depressed habitus and larger eyes; from *Cicindela* by combination of depressed body form, nocturnal activity, and wetland-bare-soil habitat association. ~11 species; PAL+ORI+AFR.
Etymology
From Greek *kallytron* (a broom, brush) — referring to setose mouth-parts or pronotum.
