Aphaenogaster amphioceanica is an extinct species of ant in the subfamily Myrmicinae known from a single possibly Miocene[1] fossil found in amber on Hispaniola.

[2] Aphaenogaster amphioceanica is known from a solitary fossil insect which is an inclusion in a transparent chunk of Dominican amber along with a spider, a mite, and six woodlice.

[2] The amber was produced by the extinct Hymenaea protera, which formerly grew on Hispaniola, across northern South America and up to southern Mexico.

The holotype was collected from an undetermined amber mine, in fossil bearing rocks of the Cordillera Septentrional mountains, northern Dominican Republic.

The antennae have a long scape that extends for 3/5 of its length past the back of the head capsule and the four end segments form the antennal club.
