''Aphaenogaster amphioceanica'' is an extinct species of ant in the subfamily Myrmicinae known from a single possibly Miocene fossil found in amber on Hispaniola. At the time of description ''A. amphioceanica'' was one of two ''Aphaenogaster'' species known from the Caribbean islands.
==History and classification==
''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.〔 The amber was produced by the extinct ''Hymenaea protera'', which formerly grew on Hispaniola, across northern South America and up to southern Mexico. The amber specimen, number Do-4629-B; which entombs the holotype, is currently preserved in the Division of Invertebrate Zoology collections at the ドイツ語:Staatliches Museum für Naturkunde Stuttgart in Stuttgart, Germany. The holotype was collected from an undetermined amber mine, in fossil bearing rocks of the Cordillera Septentrional mountains, northern Dominican Republic.〔 The amber dates from at least the Burdigalian stage of the Miocene (16-20 Ma), based on studying the associated fossil foraminifera and may be as old as the Middle Eocene (about 40 Ma), based on the associated fossil coccoliths. This age range is due to the host rock being secondary deposits for the amber, and the Miocene age range is only the youngest that it might be.〔
The fossil ant was first studied by paleoentomologist Maria De Andrade of the University of Basel. De Andrade's 1995 type description of the new species was published in the Swiss journal ''Stuttgarter Beitrage zur Naturkunde (B)''. The specific epithet ''amphioceanica'' is a combination of the Greek "amphi" meaning ''around'' and "oceanicus" meaning ''of the ocean'' in reference to the Caribbean and the Indo-Pacific, aince the nearest related species are found in the Indomalaya ecozone.〔 The six woodlice were described as paratypes of the extinct species ''Pseudarmadillo cristatus'' in 1984.〔
