Genus
Euryarthron
23 species
*Euryarthron* Guérin-Méneville, 1849 is a large Afrotropical tiger beetle genus comprising 22 species distributed across sub-Saharan Africa. These metallic, cylindrical beetles range from 10 to 18 mm and are active nocturnally, setting them apart from most of their diurnal relatives. Adults frequent open, wet habitats, moving across compacted laterite, clay-pan, and sandy substrates. The name derives from the Greek *eurys* (wide) and *arthron* (joint), alluding to the broad-jointed appearance of the antennae or legs.
Diagnosis
DIAGNOSIS — *Euryarthron* Guérin-Méneville, 1849. Body 10–18 mm, elongate-cylindrical; L:W ratio 2–3. Coloration metallic. Wings fully developed. Eyes medium. Labrum transverse. Nocturnal activity. Habitat: open wet ground; larvae in compacted laterite, clay-pan, or sandy substrate (sub-Saharan Africa). Afrotropical distribution; 22 species. Distinguished from all potential confusion genera by combination of nocturnal habit, metallic cylindrical body 10–18 mm, and Afrotropical open-wet habitat association.
Etymology
Greek eurys (wide, broad) + arthron (joint, limb segment), referring to broad-jointed appearance of antennae or legs; Guérin-Méneville (1849).
