Abstract

A morphology-based cladistic analysis was conducted of the coastal rove-beetle subgenera EmplenotaCasey and TriocharaBernhauer of the genus AleocharaGravenhorst. We used 36 adult characters from the all ten Emplenotaand three Triocharaspecies, and two outgroups, resulting in a single tree. The topology within the Emplenotaclade shows a clear pattern of species diversification that correlates well with the biogeographical distribution of this taxon. The Emplenotaclade was phylogenetically divided into three, consisting of a Nearctic clade forming a sister group relationship with the Eastern Palearctic clade, and a basal Western Palearctic evolutionary grade. In contrast, the geographical origin of Triochararemains unclear due to a paucity of information and difficulties in interpreting the distributional data.
