Studies on Neotropical crickets: Aclodes paz n. sp. a new phalangopsid cricket (Orthoptera: Phalangopsidae) from the Santander caves, Colombia.

Aclodes paz n. sp. a new troglophilous species from the caves of the municipalities of La Paz and San Vicente del Chucur, Santander, is described. An overview of the taxonomic history of the tribe Aclodini and the genus Aclodes is provided, to understand the recent taxonomic changes in the group. The species is named in honor of La Pazs municipality and the desire of Colombians and other inhabitants of the world who have conflicts in their territories (the cricket of peace). Finally, the habitat and taxonomy of the genus are discussed.

Studies on Neotropical crickets: A new Gryllotalpella species (Orthoptera: Gryllotalpidae) from Brazilian Amazon.

The genus Gryllotalpella is redescribed, and Gryllotalpella mendesi n. sp. is described from the Brazilian Amazon. The key to the species is also updated, and the status of the specimen identified as Gryllotalpella minor by Rehn in 1917 is clarified. Finally, a map with the distribution of the currently known species is provided, and the status of the species described in past centuries is discussed.

Studies on raspy crickets: Caudafistulus rubrinervosus (Serville, 1838) n. comb. (Orthoptera: Gryllacrididae).

Caudafistulus n. gen. is described to accommodate Brachybaenus rubrinervosus, a species of Raspy Cricket from the Colombian Andes, endemic to the highlands of the Aburra Valley and the eastern subregion of the department of Antioquia. Caudafistulus rubrinervosus n. comb. differs from Brachybaenus species, due to its conspicuous frontal ocellus, male terminalia with processes on the tenth tergite, subgenital plate modified, and genitalia with sclerotized areas, being one of the few genera of gryllacridids known with this peculiarity in the world. Finally, the similarity of copulatory structures with old-world taxa and their possible function for mating is discussed.

Studies on Neotropical Pseudophyllinae: The status of the genus Brachyauchenus Brunner von Wattenwyl, 1895 and its species (Orthoptera: Tettigoniidae: Pseudophyllinae: Platyphyllini).

In this contribution to the subfamily Pseudophyllinae in the Neotropics, we focus on reviewing the status of the genus Brachyauchenus and its four included species. After this revision, the genus remains monotypic, including only B. castaneus (type species), so it is necessary to provide a new diagnosis, since the current has characteristics of species that in the past was moved to Triencentrus, in addition to the characteristics of the species that are being excluded here. B. castaneus is redescribed to complement the characteristics of the genus, the unknown female is described, and new distribution data are provided, refuting the presence of this species in Bogot, Colombia, its type locality. Brachyauchenus festae and B. minutus are grouped into the new genus Mikrischyrum n. gen. (Platyphyllini) which is similar to Baliophyllum and Drepanoxiphus, and a key is provided to differentiate these species. Brachyauchenus varicosus is being moved to the genus Stenoschema (Pleminiini), restricting the distribution of Brachyauchenus to the center and north of the eastern slope of the Colombian Andes and the new genus in Panama and the Peruvian Amazon. A map is included with the distribution data of the species studied here. Finally, the variation of the coloration of some species and the current taxonomic panorama of the tribe Platyphyllini are discussed.

The status of Micronotus Hancock, 1902 species (Orthoptera: Tetrigidae).

In this contribution, we focus on the status of the genus Micronotus and its four species. After this revision, the genus only includes two of the four species, being synonymized Micronotus dubius n. syn. under M. quadriundulatus; includes within the genus M. andeanum n. comb. (transferred from the genus Tetrix) and confirming the status of M. asperulus. Micronotus is redescribed, including additional characters, and a key is provided to identify the three species considered as valid. Micronotus caudatus, is located in the new genus Danielatettix n. gen., by differing from and not fitting the diagnostic characteristics of Micronotus or another known genus of Tetriginae. The color variation of Danielatettix caudatus n. comb. is documented, and under this species its synonymized: Paratettix attenuata n. syn., P. hastata n. syn. and P. ignobilis n. syn. Finally, the distribution of the studied species and the taxonomic panorama of Tetriginae in the Neotropics are discussed.
