Diversification deep in the heart of Texas: seven new grasshopper species and establishment of the Melanoplusdiscolor species group (Orthoptera, Acrididae, Melanoplinae)

Melanoplusdiscolor and Melanopluskendalli were previously placed in the texanus species group. Here seven new species are described from central Texas and the combined nine species placed into the discolor group based on emergence time and shape of the male terminalia and genital structures. Six of these new species are from the Edwards Plateau, a known area of high endemism. Species of the discolor group are inhabitants of shortgrass or mixed-grass prairies, Ashe juniper or oak savannas.
