A new species of fossil mosquito, Toxorhynchites (Toxorhynchites) mexicanus, is described from Mexican amber. This species differs from all extant species of the genus by having a strong bristle posteriorly on the postpronotum and it differs from all species of the subgenus Toxorhynchites by having the unique combination of a short rm index (1.3) and conspicuous caudal tufts of setae on the abdomen. This is the first record of the Old World subgenus Toxorhynchites in the New World.
