Is a fossil species of ants ( Formicidae ), the only member of the genus Cananeuretus from the subfamily Aneuretinae ( North America , Canada , Alberta , Canadian Amber , Grassy Age , Medicine Hat, Campanian tier , Foremost Formation , Cretaceous period , age about 80 million years).

Description
Scape of the antennae 0.46 mm, head length 0.52 mm, mesosome length 3.1 mm. Mandibles of Cananeuretus primitive type with 4 teeth, of which the largest basal. The complex eyes are small, located in the lower half of the head, ocells are absent. Antennae 12-segmented. Propodeum rounded, without teeth or protrusions. The species was first described in 2005 by American Mirmecologists Michael Angel and David Grimaldi ( USA ). The generic name Cananeuretus is associated with the place of detection (Canada) and the name of the type genus of the subfamily ( Aneuretus ), and the species occidentalis is given along the western part of the location of this find (from the west, occidentalis ), since this species became the first Mesozoic representative of the subfamily from the Western Hemisphere [1 ] [2] [3] . Cananeuretus is one of the six genera and species described from the neighborhood of the village (hamlet) of Grassi Lake , along with Canapone dentata , Chronomyrmex medicinehatensis , Eotapinoma macalpini , Haidoterminus cippus and Sphecomyrma canadensis [2] [4] .
