摘要

Here we report on the first molecular phylogenetic study of the phorid genus Anevrina using a combination of nuclear (28S) and mitochondrial (12S, ND1 and CO1) genes for a total of 2220bp. Both maximum parsimony and Bayesian analyses recovered Anevrina as a monophyletic lineage within a broad sampling of phorid taxa that included 13 genera from 4 subfamilies. The higher-level relationships of phorid taxa based on the molecular tree were (Sciadocerinae + ((Hypocerinae + Phorinae) + Metopininae))). Relationships of species within Anevrina were also fully resolved with strong branch support in the form of posterior probabilities, bootstrap values, and decay indices. Two major clades were identified within Anevrina: ((A. luggeri + A. macateei) + (A. curvinervis + A. unispinosa)), which was joined as a sister group to ((A. variabilis + A. thoracica) + (A. olympiae + A. urbana)). A new and first Neotropical species, A. neotropica, from Costa Rica is described, illustrated, and included in an updated world key. Anevrina setigera (Loew, 1874) is synonymized with A. urbana (Meigen, 1830), new synonymy.
