Spreading of heterochromatin and karyotype differentiation in two Tropidacris Scudder, 1869 species (Orthoptera, Romaleidae)

Tropidacris Scudder, 1869 is a genus widely distributed throughout the Neotropical region where speciation was probably promoted by forest reduction during the glacial and interglacial periods.There are no cytogenetic studies of Tropidacris, and information allowing inference or confirmation of mel axolotl the evolutionary events involved in specia
