Genus
Waltherhornia
2 species
*Waltherhornia* is a rare, monotypic Afrotropical tiger beetle genus whose single species inhabits open, wet habitats on compacted laterite, clay-pan, and sandy substrates across sub-Saharan Africa. Small-bodied and metallic in coloration, these beetles are nocturnal hunters with large, protuberant eyes suited to low-light pursuit. Named in honor of the German entomologist Walther Horn (1871–1939), the genus stands as a tribute to a founding figure of Cicindelidae systematics.
