Chalcidoidea is one superfamily represented by 19 families in the nearctic region, being the most important in biocontrol of agricultural pests. In México, about 800 species were recorded in the Noyes 1998 CD. Only few specialists are working at the species level in this country. The authors collected information on the Chalcidoidea present in the States of Tamaulipas and Nuevo León, and also collected wasps of some families in different localities and identified them. As a result, 18 families, 196 genera and 361 species have been recorded for those States; only Tetracampidae has not been recorded. Encyrtidae (126 species, 90 genera) was the best studied, followed by Eulophidae (67 species, 36 genera), Aphelinidae (40 species, 14 genera), and Mymaridae (20 species, 7 genera). Anagyrus, Cheiloneurus, Chrysocharis, Cirrospilus, Omphale, Aphytis, Encarsia and Gonatocerus were the genera with more species. A complete list will be shown in the presentation.
