Eoneria blanchardi Aczél, 1951

(Figs 1B, 2C, 8B)

Diagnosis. Head elongate, twice as long as antenna and dorsally straight. Arista dorso-apical. Inner process of pedicel triangular and narrow. Antennal base clothed with a dense pruinescence and consequently opaque. Three fronto-orbital setae. Vibrissa present. Gena and postgena wide and ventrally rounded, with a set of yellow setulae posteriorly. Parafacial wide and anteriorly rounded. Two well-developed notopleural setae. Pleuron with grey pruinescence. Scutum with five to eight presutural and postsutural dorsocentral setae that vary in size.

Material examined. Mexico. Querétaro. Barranca de Cocheros, San Juan del Río [20.332986, -100.094675], 1-29.x.2019, S. Rodríguez, C. Pedraza, E. Nuple, L. García, 3 females (2 CNIN, 1 CARF) .

Distribution. Mexico * (Querétaro), Venezuela, Brazil (Bahia, Mato Grosso do Sul, Paraíba, Pernambuco), Paraguay, Argentina (Jujuy, Chaco, Corrientes, La Rioja) (Braga et al. 2017, Sepúlveda & Souza 2020).

Remarks. For a long time, Eoneria species were know exclusively from southern South America (Paraguay, Argentina (Jujuy, Chaco, Catamarca, Corrientes, La Rioja)). More recently, new specimens have been recorded from Venezuela and Brazil (Paraíba, Pernambuco, Bahia, Mato Grosso do Sul) (Sepúlveda et al. 2013; Braga et al. 2017; Sepúlveda & Souza 2019). Our record from Mexico is the northernmost record of the species, indicating that its distribution may not only be wide in South America, but also in Central America. In addition, the genus Eoneria is closely related to the unique Neriidae fossil genus described, found in the Mexican amber ( Palaeonerius Sepúlveda & Gomes). This affinity is based mainly on the characters of the Eoneria -group, which include the presence of well-developed setae on head and thorax (e. g. occipital, discal scutellar, and anterior notopleural setae), a pruinose antennal base, and the lack of strong and short setae positioned at the marginal protuberance on syntergite 1 + 2 (Sepúlveda & Gomes 2021).
