Santos, Bernardo F. | Aguiar, Alexandre P.
The taxonomic limits of Loxopus Townes are reviewed. The genus is characterized by the lateral margin of the clypeus projecting as subtriangular lobe; lateral lobes of fourth tarsomeres distinctly longer than mesal lobes; fore wing vein 3r-m absent; hind wing vein 2-1A absent or vestigial; and first metasomal tergite with a basolateral tooth. It occurs from Mexico to southern Brazil. Nine species are recognized, of which six are described as new: L. dodecius Santos et Aguiar, L . duckei Santos et Aguiar, L. exius Santos et Aguiar, L. ichilus Santos et Aguiar, L. tenuis Santos et Aguiar, and L . venezuelanus Santos et Aguiar. The type species, L. australis Townes, and L . multicolor Kasparyan et Ruíz-Cancino are redescribed, and a diagnosis is provided for L. unicolor Kasparyan et Ruíz-Cancino, not examined. All studied species are illustrated and distribution records are mapped. An identification key for the species of Loxopus is presented.
