On the basis of material collected over several years, 13 genera and 33 species of Melanoplinae of northeastern México are treated. Four species are considered as new records: Melanoplus arizonae Scudder, 1878, M. bivittatus (Say, 1825), M. regalis (Dodge, 1876) and M. sanguinipes sanguinipes (Fabricius, 1798). A new species is described: Huastecacris fariensis n. sp. Twenty species are endemic to México: new information on geographic distribution and relative abundance is provided for all species treated. Melanoplus Stl, 1873 and Phaedrotettix Scudder, 1897 were the most diverse genera, with 13 and five species, respectively. The most common species, in order of abundance, were Phaulotettix compressus Scudder, 1897 (231 specimens), Phaedrotettix violai Fontana & Buzzetti, 2007 (229), Huastecacris zenoni Fontana & Buzzetti, 2007 (188), Phoetaliotes nebrascensis (Thomas, 1872) (161), Melanoplus flavidus Scudder, 1878 (110) and Huastecacris truncatipennis Fontana & Buzzetti, 2007 (109). Simpson's index (D) was estimated at 0.07 and Simpson's biodiversity index (1-D) at 0.93. AFLP molecular analysis supported morphological separation for some of the taxa studied and confirmed the presence of a new species of Huastecacris: H. fariensis n. sp.
