Abstract

The rove beetle subfamily Aleocharinae is the largest subfamily of animals known in terms of species richness. Two small aleocharine tribes, Gymnusini and Deinopsini, are believed to be a monophyletic clade, sister to the rest of the Aleocharinae. Although the phylogenetic relationships of the extant lineages have been well investigated, the monophyly of Gymnusini has been questioned due to a series of previous studies and the recent discovery of the aleocharine †Cretodeinopsis Cai & Huang (Deinopsini) from mid-Cretaceous Burmese amber. Using an additional specimen of †Cretodeinopsis and well-preserved specimens of †Electrogymnusa Wolf-Schwenninger from Eocene Baltic amber, we present here two types of morphology-based phylogenetic analyses, employing all extant/extinct genera of Gymnusini and Deinopsini for the first time. The maximum parsimony and Bayesian analyses recovered a monophyletic clade of the two tribes combined, but each analysis suggested nonmonophyly of Gymnusini. In agreement with the results of the present study, we synonymize Deinopsini syn.n. under Gymnusini sensu n., by priority.
