Genus
Habroscelimorpha
35 species
*Habroscelimorpha* Dokhtouroff, 1883 is a genus of roughly twenty tiger beetle species tied to coastal and saline habitats, where intertidal and supratidal sands serve as both foraging ground and larval nursery. These medium-to-large beetles (12–17 mm) wear a pale metallic livery patterned with contrasting spots — cryptic camouflage against sun-bleached shoreline. Enormously protuberant eyes give them exceptional visual acuity suited to the open, structurally sparse tidal zone. Unusually among tiger beetles, adults are nocturnal hunters, prowling wet sand margins after dark.
Diagnosis
DIAGNOSIS — *Habroscelimorpha* Dokhtouroff, 1883. Body 12–17 mm, cylindrical, elongate-cursorial; L:W ratio 2–3. Fully winged. Head wider than pronotum; eyes very large, strongly protuberant. Labrum transverse. Pronotum subquadrate. Elytra elongate, often parallel-sided; ground colour pale metallic with spots. Nocturnal. Habitat: intertidal and supratidal sand; larvae in moist sand above tideline. Separated from *Cicindela* by pronounced eye protuberance, pale colouration, and strict tidal-substrate association; from *Ellipsoptera* by larger body size, more cylindrical habitus, and nocturnal activity pattern.
Etymology
From Greek *habrós* (delicate, graceful) + *skélos* (leg) + *morphḗ* (form) — "of delicate-legged form".
