The genus Bactrophora Westwood, 1842 comprises only two species known from Central America and northern South America, with a notable scarcity of collected specimens. Herein, we provide the first records of the presence of this genus in Brazil. These new records, based on entomological collection data and photographic records, extend the known distribution of Bactrophora dominans Westwood, 1842 to include the Brazilian Amazonian region. Both records emphasize the importance of natural history collections and the significance of the iNaturalist web-based application as an instrumental tool in this discovery.

Toledopizia Chamorro-Rengifo & Braun, 2010 is a poorly known monotypic genus of Copiphorini. The only known specimen is the female type of T. salesopolensis (Piza, 1980). In this contribution, we present an updated description of this species, describing the unknown male, and provide biological and bioacoustic data. We also describe color variation, update the distribution data, and extend the known distribution of the species to two localities in Paraná State and another two in São Paulo State.

This contribution describes a new genus and three new species of Agraeciini from the Brazilian Atlantic Forest, Warimiri madiba gen. et sp. nov., Warimiri zumbi gen. et sp. nov., and Warimiri karutasywa gen. et sp. nov.. The new genus resembles the genera Hyperomerus Redtenbacher and Dectinomima Caudell and probably is closely related to them, but the internal and external male genitalia components distinguish the three taxa. We also provide a brief comment about the function of the internal components of the phallic complexes of Warimiri gen. nov. and Hyperomerus.

This paper accomplishes three tasks: Firstly, description of a new species, Uchuca almeirina sp. nov., from the Brazilian Amazon Rainforest, specifically from Monte Dourado, Almeirim, Pará. Secondly, it is proposed that Uchuca macroptera Montealegre-Z & Morris, 2003 be made a synonym of Uchuca ferreirai (Piza, 1976). Thirdly, a compilation of the generic distribution is presented, which includes new records of Uchuca amacayaca Montealegre-Z & Morris (2003) in Brazil and Uchuca similis Montealegre-Z & Morris (2003) in Colombia and Brazil, and the amplification of the occurrences of U. ferreirai.

A new genus of small phalangopsids (Orthoptera: Phalangopsidae) from the foothills of the Colombian Andes is described. Crinklyalis n. gen. is distinguished from the other genera of the subtribe Strogulomorphina (Paragryllini) by the modification in the mesal region of the tegmina, apparently an acoustic chamber; reduction of wing venation; male genitalia tubular, elongated and mostly membranous, with only the distal section sclerotized. Additionally, the key for the identification of the genera of the subtribe was updated, and the morphology of the new genus was discussed, as well as distributional gaps that currently exist for the Strogulomorphina taxa.

Here we describe a new genus and species of cricket belonging to Lernecina from the Brazilian Atlantic Forest. It is presently known only from Ubaíra, State of Bahia, Brazil. The new genus is the only known member of this subtribe having males with a mostly white and hyaline dorsal field of the forewing (an additional genus with that condition is in the process of being described).

A new monotypic genus, Mellogryllus mutus n. gen. et n. sp., is described from the dense ombrophilous forests of the Brazilian coastal Atlantic Forest. This new genus is included within the genus-group Miogryllae due to the structure of the male genitalia. The key for the genera of the Group Miogryllae is also updated. Finally, the morphological particularities of Mellogryllus n. gen. are discussed, such as the presence or absence of tympanum in the different sexes, variation in the number of spurs on the legs, and the modification of the first pair of legs for underground life.
