By combining different research disciplines, biologists can understand natural processes in a broader way. Here, we combine both taxonomic and bioacoustic methodologies to provide the first observations of the morphology, geographical distribution, and the acoustic behavior of the monotypic genus Andeophylloides n. gen.

The tribe Otteiini is a group of cave crickets, that were believed only to inhabit the Greater Antilles (Cuba, Cayman Islands, and Hispaniola). However, when reviewing and studying similar cave crickets in Mexico, their relationship was proven with island taxa, expanding their distribution to the continental area, from the Yucatan Peninsula to the Gulf and Northeast of Mexico. Herein, the genus Paracophus is divided, and three additional genera are described: Hubbellcophus n.

The Batrachideinae subfamily is a well-defined and taxonomically stable taxon, with a pantropical distribution and an important representation in the Neotropical region. In this study, the characters and distributions of the genera and species are discussed based on a morphological analysis and a key to genera of the American Batrachideinae is also provided. New synonymies are established: Tettigidea Scudder, 1862 = Eotetrix Gorochov, 2012 syn.

Lophotettiginae is a small, peculiar taxon of the Neotropical region, characterized mainly by median carina compresso-cristated or leaf-like crest, antennae flattened laterally and expanding from the base to the apex (incrassate shape). This subfamily has only one genus known as Lophotettix Hancock, 1909 that comprises five species. Here, we reviewed the types of the five known species, highlighting morphological aspects that distinguish the species from each other and from other tetrigids.

In this contribution to the study of gryllacridines or raspy crickets (Orthoptera: Gryllacrididae), a new proposal for classification of this family is provided, dividing it into two subfamilies and ten tribes that includes most of the 114 known genera to date (including the new genera described here). It describes and redefines two subfamilies: Hyperbaeninae n. subf.

We describe a new species of Pachyphloea from the Natural National Park (NNP) Chicaque, Cundinamarca in the Colombian Andes, providing data on the structure and variability of its eggs. In addition, we synonymize Grylloclonia n. syn.

The Amazon rainforest is the world's most extensive tropical rainforest, holding a considerable ecological and taxonomic diversity. Speciation in this region arises from multiple factors, such as topography, climate fluctuations, oceanic transgression, vegetation and the delimitation of zones circumscribed by sub-basins within the greater Amazon basin. Different scenarios have been proposed to better understand the diversification of Amazonian taxa, whether by Pleistocene refugia or by areas of endemism.
