Decapod crustacean specimens from the middle Eocene San Juan Formation in central Chiapas represent the first record of Eocene decapods in southern México. New taxa include:Dardanus mexicanusnew species (Diogenidae),Lophoranina cristaspinanew species, Notopus minutus new species (Raninidae);Verrucoides stenohedranew genus and new species (Xanthidae);Stoaplax nandacharenew genus and new species (Goneplacidae); andViapinnixa alvarezinew species (Pinnotheridae).Verrucoides verrucoidesnew genus and

In addition, the fauna includesCallianassasensu lato sp.,Laeviraninasp.,Calappiliacf.C. hondoensisRathbun, 1930,Eriosachilasp., and indeterminate calappid and xanthoid taxa. This assemblage bears close relationship with coeval faunas in the Tethyan region of southern Europe and southern North America and with Paleocene faunas of Greenland, strengthening the evidence for previously described patterns of dispersal within the Decapoda.
