Taxonomy and phylogeny of the Eoneria-group (Diptera, Neriidae)

Abstract

The Eoneria-group was proposed to gather species with opaque antennal base from all biogeographical regions. Recently, the Eoneria-group was redefined to comprise only three genera from the Neotropical Region: Antillonerius, Eoloxozus and Eoneria. Herein, we redescribe the species of the Eoneria-group and perform a phylogenetic analysis based on 49 morphological characters. Our results corroborate the monophyly of the Eoneria-group (excluding Antillonerius bistriatus (Williston)), supported by nine synapomorphies. Antillonerius solitarius (Johnson) stat. rev. is revalidated from synonymy with Antillonerius cinereus (Röder) and a key for the species in the Caribbean islands is provided. New combinations are proposed for Eoloxozus sabroskyi Aczél, which is transferred to Eoneria, and Nerius bistriatus Williston, which is transferred to Glyphidops. Additionally, new records of E. aczeli Sepúlveda & de Carvalho are provided for Venezuela and of E. blanchardi, for Venezuela and Paraguay.

Revalidation and taxonomic revision of Teloneria Aczél (Diptera, Neriidae), with description of two new species

“…The inner process of pedicel is a diagnostic character for Neriidae (Buck 2010) and the differences in its shape have been broadly used as diagnostic for generic identification (Aczél 1961;Buck 2010;Sepúlveda & Souza 2020). Two main shapes have been described for Neotropical species of Neriidae: broad triangular, characteristic of Nerius Fabricius, 1805 (Fig.…”

“…The number of dorsocentral setae is a taxonomically informative character for the determination of the genera in Neriidae (Aczél 1961;Sepúlveda & Souza 2020). The presutural dorsocental seta is only present in Chaetonerius, Eoneria Aczél, 1951, Odontoloxozus Enderlein, 1922, Nipponerius Cresson, 1926, Protonerius de Meijere, 1924and Stypocladius Enderlein, 1922, and the number of postsutural dorsocentral setae is accurately constant amongst the genera of Neriidae Cerantichir Enderlein, 1922, Glyphidops Enderlein, 1922, Gymnonerius Hendel, 1913, Longina Wiedemann, 1830, Loxozus Enderlein, 1922 (Fig.…”
