A morphology-based cladistic analysis was conducted of the coastal rove-beetle subgenera Emplenota Casey and Triochara Bernhauer of the genus Aleochara Gravenhorst. We used 36 adult characters from the all ten Emplenota and three Triochara species, and two outgroups, resulting in a single tree. The topology within the Emplenota clade shows a clear pattern of species diversification that correlates well with the biogeographical distribution of this taxon. The Emplenota clade 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 Triochara remains unclear due to a paucity of information and difficulties in interpreting the distributional data.

Kistnerella malayensis Kanao & Maruyama, gen. et sp.n. (Coleoptera: Staphylinidae: Aleocharinae) is described from Ulu Gombak, Selangor, Peninsular Malaysia. This new genus belongs to the termitophilous subtribe Compactopediina in the tribe Aleocharini, and is associated with Longipeditermes longipes (Haviland, 1889) (Isoptera: Termitidae: Nasutitermitinae). A key to the genera in Compactopediina is given. The phylogenetic relationships of the genera are investigated, and the host termite relationships and the systematic position of Compactopediina are discussed.
