Abstract Orthoptera have some of the largest genomes all insects. At same time, architecture their remains poorly understood. Comparative cytological data across a wide range taxa, even for basic parameters such as chromosome number, may provide important insights into evolution these and help answer question why species attained large genome sizes. We collected compiled more than 1,000 records...

Based on the examination of types and additional materials, the morphology of Pternoscirtapulchripes Uvarov, 1925 and Flatovertex species were reviewed. As a result of our study, the genus Flatovertex Zheng, 1981 was synonymized with the genus Pternoscirta Saussure, 1884, the species Flatovertex cyaneitibialis Zhang & Han, 2010 was synonymized with Pternoscirta caliginosa (Haan, 1842), Flatover...

Patterns of colonization and diversification on islands provide valuable insights into evolutionary processes. Due to their unique geographic position and well known history, the Galapagos Islands are an important model system for evolutionary studies. Here we investigate the evolutionary history of a winged grasshopper genus to infer its origin and pattern of colonization in the Galapagos arch...

The Andean Mountain range has been recognized as one of the biodiversity hotspots of the world. The proposed mechanisms for such species diversification, among others, are due to the elevation processes occurring during the Miocene and the intensive glacial action during the Pleistocene. In this study we investigated the diversification history of the grasshopper Trimerotropis pallidipennis spe...
