Genus
Poecilochila
16 species
In the leaf-littered understorey of Neotropical forests, *Poecilochila* beetles move after dark, hunting from low vegetation and forest floor alike. This small genus of around four species spans the Neotropical region, their metallic bodies gleaming against bark and foliage in torchlight. Semi-arboreal habits set *Poecilochila* apart from most ground-hunting tiger beetles, with larvae developing in soil close to plant bases. Medium-bodied and fully winged, these nocturnal hunters represent a distinctive thread in the rich Odontocheilina radiation of the Americas.
Diagnosis
DIAGNOSIS — *Poecilochila* (Poecilochila) Rivalier, 1969 s.str. Body medium, 9–13 mm; habitus cylindrical, elongate-compact (L:W ratio 2–3). Coloration metallic with pale spots. Labrum subquadrate. Eyes medium, moderately protuberant. Pronotum slightly elongate, sides weakly rounded. Elytra elongate, fully developed; hind wings fully developed (macropterous). Activity nocturnal; semi-arboreal. Larvae in soil near plant bases. ~4 species; Neotropical.
Etymology
Greek poikilos (variegated, many-colored) + cheilos (lip), referring to the variably colored labrum; Sumlin (1979).
