Gerontoformica Nel and Perrault

Gerontoformica Nel and Perrault, 2004: pg. 24. Type species: G. cretacica Nel and Perrault, by original designation. In Albian-aged amber from France.

Sphecomyrmodes Grimaldi and Engel, 2005: pg. 5. Type species: Sphecomyrmodes orientalis, by original designation. In Burmese amber. New synonymy.

Diagnosis (Emended). Distinguished from other Cretaceous genera by an uninterrupted row of peg-like denticles on the anterior margin of the clypeus; mandibles falcate, with one large apical tooth and one preapical tooth. The revised diagnosis and new generic synonymy is based on re-examination by one author (P.B.) of the type specimen, officially housed at the National Museum of Natural History, Paris. Species formerly placed in Sphecomyrmodes [16, 20, 25] are now placed in Gerontoformica .
