Eoneria Aczél 1951: 570 . Type-species: Eoneria blanchardi Aczél, 1951 (original designation); Aczél 1961: 276 (key); Steyskal 1968: 2 (catalogue); Buck 2010: 818 (key).

Diagnosis. Anterior margin of frons straight. Behind the ocellar tubercle is a small protuberance between the postocellar setae. Body setae longer than those in the other species of neotropical Neriidae and not spine-like. Head moderately elongate, twice as long as antennae. Three pairs of fronto-orbital setae. Antennal base clothed with a dense yellow dusting and consecuently only subshiny. Inner process of pedicel elongate, triangular, reaching the proximal half of the first flagellomere. First flagellomere yellowish and ovate, with tiny white pilosity. Arista brown and micropilose on the dorso-apical margin of the first flagellomere. Postocellar setae large and convergent. Vibrissa present. Thorax with one dorsal gray pruinose vitta equal in width with scutellum, separated by a narrow, median, yellowish brown stripe; pleuron with gray pruinescence. Six pairs of dorsocentral setae, variable in size. Scutellum with one pair of apical scutellar setae and one pair of weak subapical setae. Mid and hind coxae with two lateral setae. Basicosta with one dorsal seta and one ventral seta. Tergite 2 with one lateral seta, subequal to anterior notopleural setae and two conspicuous setae on posterior margin.

Distribution. Colombia, Brazil, Argentina.
