Genus

Pseudoxycheila

24 species

*Pseudoxycheila* Guérin-Méneville, 1839 is a robust Neotropical tiger beetle genus of approximately 24 species distributed across Andean foothills and montane forests of South America. These medium to large beetles, measuring 12–22 mm, display striking metallic coloration with contrasting spots against a dark background. Nocturnal hunters of the forest floor, they favour moist riparian banks and clay-loam substrates, where larvae excavate vertical burrows in clay soil. With their elongate mandibles and oval body outline, they rank among the most distinctive oxycheiline genera of the Andean region.

Diagnosis

DIAGNOSIS — *Pseudoxycheila* Guérin-Méneville, 1839. Body 12–22 mm, robust, oval (L:W ratio <2.0). Head wider than pronotum; eyes medium, correlated with forest-shade habit. Mandibles elongate (Oxycheilini condition). Coloration metallic with distinct pale/orange elytral spots. Wings fully developed. Nocturnal; habitat moist forest floor, riparian clay-loam banks; larvae in vertical clay burrows. Separated from *Oxycheila* by more compact habitus and distinct elytral maculation pattern; no other confusion genera recorded.

Etymology

From Greek *pseudḗs* (false) + Oxycheila — "false Oxycheila", separated from related Oxycheila.
