Revision of the Neotropical Neurigoninae (Diptera: Dolichopodidae) I: Coeloglutus Aldrich, Neotonnoiria Robinson, and Paracoeloglutus gen. nov., with the definition of the tribe Coeloglutini stat. nov.

The Neotropical species of the tribe Coeloglutini NEGROBOV stat. nov., comprising the genera Coeloglutus ALDRICH, Neotonnoiria ROBINSON and Paracoeloglutus gen. nov. (Diptera: Dolichopodidae) are revised. Diagnoses and a key to the genera are given. The species Coeloglutus concavus ALDRICH and Neotonnoiria maculipennis (VAN DUZEE) comb. nov. are redescribed, and Paracoeloglutus chilensis spec. nov. is described as new. The following species are placed in synonymy: Coeloglutus sinuatus (PARENT) syn. nov. and Coeloglutus bicoloripes VAN DUZEE syn. nov. with Coeloglutus concavus ALDRICH; Neotonnoiria angustifacies (PARENT) syn. nov. with Neotonnoiria maculipennis (VAN DUZEE). A phylogenetic analysis of the included genera and species is given. The tribe Coeloglutini forms a distinct monophyletic group. The new genus Paracoeloglutus is probably the most ancestral clade of the tribe.
