Genus
Pronyssa
7 species
*Pronyssa* Bates, 1874 is a small genus of roughly eight Neotropical tiger beetles found in the forests of Colombia, Ecuador, and Peru. Unlike most cicindelids that hunt on open ground, *Pronyssa* is arboreal, stalking prey on tree bark under cover of darkness. Larvae develop in burrows excavated within bark — a striking departure from the sandy or muddy substrates favored by their relatives. These metallic, medium-bodied beetles represent one of the most ecologically distinctive lineages in the Neotropical tiger beetle fauna.
Diagnosis
DIAGNOSIS — *Pronyssa* Bates, 1874 Body medium, 9–16 mm; form elongate, notably depressed (flattened). Integument metallic. Labrum transverse. Eyes medium, laterally directed. Fully winged. Nocturnal; arboreal on bark in Neotropical forests (Colombia, Ecuador, Peru). Larvae in bark burrows. Assigned to Cicindelini: Cicindelina. Type species: *Pronyssa belti* Bates, 1874 (by monotypy). No confusion genera recorded for this genus.
Etymology
From Greek *pro-* (forward) + *nyssa* (nymph) — coined name by Bates 1874; possibly evoking the swift-running predatory habits.
