Genus
Dromochorus
4 species
*Dromochorus* Guérin-Méneville, 1845 is a small genus of nocturnal tiger beetles inhabiting open sandy soils and forest-edge habitats across the central and southern United States and northern Mexico. Unlike most of their flashy diurnal relatives, these compact, dark-bodied beetles are brachypterous — permanently grounded, their fused elytra bearing no pale markings whatsoever. Larvae develop in vertical burrows dug into bare sand, a habit as specialized as the adults that emerge from them.
Diagnosis
DIAGNOSIS — *Dromochorus* Guérin-Méneville, 1845 Body 8–14 mm, robust, oval (L:W <2.0). Dorsal coloration uniformly dark, matte; elytral maculation absent (H04=0, H05=0). Hind wings absent (brachypterous; I01=2). Eyes moderate, less protuberant than typical Cicindelina. Pronotum subquadrate; head wider than pronotum. Nocturnal; larvae in vertical sand burrows. Separation from *Cicindelidia*: brachyptery combined with complete absence of pale elytral markings diagnostic.
Etymology
From Greek *drómos* (running) + *chorós* (dance) — "running dancer".
