Some representative Pselaphinae (Staphylinidae)
Members of the staphylinid subfamily Pselaphinae were for many years considered a distinct family. They are now considered to represent a terminal lineage of the omaliine branch of the Staphylinidae (Newton and Thayer, 1995). In general, pselaphines are small (0.5-5 mm) predators of forest litter and other moist habitats. There are about 9,500 described species worldwide, but a great many additional specise are undescribed, especially in tropical regions. The following is a series of representatives showing the array of body types and specialized structures that are found in this fascinating group of beetles. Museum Director Carlton is a specialist of this subfamily.
Sonoma tolulae (SE U.S.) represents one of the most primitive tribe, the Faronini, of the subfamily and is has the general appearance of a typical staphylinid.
Bythinoplectus dechambrieri (Belize) is a representative of the primitive pantropical tribe Bythinoplectini.
Pseudactium ursum (Ark., U.S.)illustrates a member of the tribe Euplectini.
Rhinoscepsis dybasi (Belize) illustrates a member of the Rhinoscepsini. Note the prominant rostrum that the antennae are attached to.
Hanfordia sp. (Belize) is a typical member of the tribe Trimiini showing a reductionist body form typical of small sized insects.
Malleoceps sp. (Dominican Republic) is a member of the Trimiini with a bizarre "hammerhead" morphology.
Endytocera cognata (Belize) is typical of the entirely neotropical tribe Jubini. Note the detail of the pronotum, showing specialized secondary sexual characters of the male.
Eupsenius sp. (Belize), of the tribe Brachyglutini, is a member of a large, mainly neotropical complex, that completely lacks body hair.
Arianops n.sp. (Ala., U.S.) is a member of the subtribe Amauropsina of the tribe Batrisini. New species of this genus of blind, wingless beetles keep turning up. Note the detail of the head showing the lack of eyes.
Arthmius bulbulus (Belize) is typical of this enormous mainly neotropical genus in the Batrisini, which contains hundreds of undescribed species. Note the dark field detail of the head showing the modified first antennal segment of the male.
Batriassymodes wagneri (Ala., U.S.) is a member of a batrisine genus endemic to southeastern U.S.
Metopioxys sp. sp. (Brazil) is a member of a bizarre neotropical batrisine genus complex of presumably myrmecophilous (ant-associated) species. For the full effect of the pronotal spines, see the side view.
