Genus
Naviauxella
21 species
Hidden in the forested laterite clearings and sandy riverbanks of South and Southeast Asia, *Naviauxella* is a small but distinctive genus of tiger beetles comprising roughly 23 species. Named in honor of Roger Naviaux, the French entomologist whose monographic work transformed our understanding of Asian Cicindelidae, the genus wears its metallic bronze and coppery elytra like armor against the leaf litter. Active after dark, these medium-sized beetles patrol bare sandy and clay-loam substrates across the Indo-Malayan region, from Myanmar and Thailand east to Vietnam and Cambodia.
Diagnosis
DIAGNOSIS — *Naviauxella* Cassola, 1988. Body medium, 8–14 mm; habitus elongate-cursorial. Head wider than pronotum; eyes large, protuberant. Labrum subquadrate. Pronotum subquadrate. Elytra elongate; ground color metallic bronze, greenish, or coppery; maculation typically with humeral lunule, median band, and apical marking. Fully winged. Nocturnal; forest habitats on bare sandy, clay-loam, or riverine substrates (Oriental). Aedeagus and labrum morphology key for species separation. Type species: *Naviauxella schillhammeri* Cassola, 1988, by monotypy.
Etymology
Named after R. Naviaux (French entomologist, monographer of Asian tiger beetles 1981-2009); diminutive feminine ending -ella.
