Andrena antoinei is an extinct species of mining bee in the family Andrenidae described from a single fossil found in a Late Oligocene lake in present-day France that existed in semi-arid conditions.

[1] Along with other well preserved insect fossils, the A. antoinei specimen was collected from layers of Late Oligocene lacustrine rock belonging to the "calcaire de Campagne Calavon" sediments.

The paleoflora preserved in the shales suggest the lake was surrounded by a mixed-mesophytic forest, though the vertebrate fauna found in the formation is more typical of a semi-arid environment.

The specific epithet antoinei is a patronym coined in honor of Antoine Michez, for the support he provided melittology.

[1] A. antoinei is one of four bee species described by Dehon and team in the PLOS ONE article, the others being Bombus cerdanyensis, Euglossopteryx biesmeijeri, and Protohabropoda pauli.
