Solving taxonomic Orthoptera problems by Near Infrared Reflectance Spectroscopy (NIRS): the case of Aganacris Walker, 1871 (Tettigoniidae: Phaneropterinae; Scudderini).

Over the last 50 years, the genus Aganacris has undergone several taxonomic changes. In this study, an infrared spectrum analysis as a complementary and alternative analysis method was carried out for 112 Aganacris specimens belonging to five species. Significant differences were observed between males and females of the species, thus taking into account a new taxonomic status for the genus and the revalidation of Aganacris sphex (Rehn) stat.

The tribe Dysoniini part IV: New species of Quiva Hebard, 1927 (Orthoptera: Tettigoniidae: Phaneropterinae) from Brazilian rainforest and some clarifications.

Two new species of the genus Quiva: Quiva buhrnheimi n. sp. and Quiva gutjahrae n.

New species of Microcentrum Scudder, 1862 (Orthoptera: Tettigonioidea: Phaneropteridae) from Amazon rainforest.

A regional study is performed for the Amazonian species of the genus Microcentrum Scudder, 1862, its proposed Microcentrum punctifrons Brunner von Wattenwyl, 1891 as nomen dubium n. stat. and two new species are described: Microcentrum amacayacu Cadena-Casteñada, Sovano n.
