Genus
Abroscelis
12 species
*Abroscelis* Hope, 1838 is a small genus of six slender tiger beetles patrolling the intertidal and supratidal sand flats of East and Southeast Asia, from Japan and Korea south to Indonesia and the Philippines. Their extraordinarily long, delicate legs — the origin of the genus name, from Greek *habrós* (delicate) and *skélos* (leg) — are a hallmark adaptation for rapid movement across unstable coastal substrates. Diurnal hunters, these beetles are tied to the narrow and demanding interface between land and sea. Their elongate, matte-coloured bodies render them remarkably cryptic against pale, wet sand.
Diagnosis
DIAGNOSIS — *Abroscelis* Hope, 1838. Body 9–15 mm; elongate-cursorial, L:W ratio >3.0; cylindrical in cross-section. Coloration dark to matte, pale bronze, sand-yellow, or pale greenish. Head wider than pronotum; eyes very large, strongly protuberant. Labrum subquadrate. Pronotum subquadrate. Legs extremely long and slender (diagnostic; cf. genus name). Fully winged. Diurnal. Habitat strictly intertidal and supratidal sand; tidal-zone restriction is the primary ecological diagnostic character for genus-level separation within Oriental Cicindelina.
Etymology
From Greek *habrós* (delicate) + *skélos* (leg) — "delicate-legged".
