One hundred and two species and thirty two genera of the four subfamilies of Pompilidae wasps, collected at localities of eight municipalities of Tamaulipas, México were recorded. Twenty one species of these are new records for the country meanwhile 88 species are new records for the state of Tamaulipas. The most abundant species were Aporus notabilis notabilis y Episyron conterminus posterus. Thirty three species are Neotropical. The results suggest that others species will be present in this region of the country and therefore more studies must be necesary to make in order to know the richness of this group of wasps.
