|scientific name Pteroloma nebrioides |
Specimens were collected from shaded leaf litter beside a stream.
This is the only Alberta agyrtine with a cordate pronotum, with a large depression in each posterior corner and one in the middle of the base. Additional important features are that the mandibles have pre-apical teeth; the antennae are gradually thickened, with the apical segments irregularly hairy [without a uniform vestiture of microsetae] and without a sharp ridge around the apex of the penultimate segments; and the frons bears a pair of pale eyespots, just where some staphylinoids have ocelli. There is a single large paramere on the aedeagus.
This species has a limited range in the Rocky Mountains and associated ranges. In Alberta it has been found in the mountains and foothills.
Meaning of name: "like Nebria". It refers to this species' similarity in shape to the ground beetle genus Nebria, whose species also have a cordate pronotum.
