Redescription and phylogenetic position of the unusual aleocharine staphylinid Dimonomera indica Cameron, 1933 (Coleoptera : Staphylinidae : Aleocharinae : Dimonomerini)

The unusual genus and species Dimonomera indica Cameron, currently placed a s the sole member of the tribe Dimonomerini, is redescribed, and illustrati ons of habitus, mouthparts, meso-metasternal areas, tarsi and male genitali a are provided. Dimonomera shares numerous characters, some of which are un ique among aleocharines, with known members of the tribe Myllaenini. It dif fers from other myllaenines, especially the type genus Myllaena, primarily in the unusual autapomorphic tarsal structure. Tarsal structure is an insuf ficient criterion for establishing a tribe exclusively to include Dimonomer a. The results of this study support the proposal that Dimonomera should be included in the Myllaenini.
