( Fig. 8 ) Comments. Piza (1980) describes this species within the genus Brachyauchenus , and its existence remained unknown for a long time to entomologists due to the restricted diffusion of the journals in which Piza published his contributions. It was so difficult to achieve some contributions of the author, that in the review of tettigonids from the Salvador de Toledo Piza Jr collection, this species was cataloged as a “phantom species” because the references were not available ( Chamorro-Rengifo & Braun, 2010 ). Recently, some of Piza’s contributions were made available online, but even the identification task is arduous; due to the brief descriptions and, in many cases, without drawings of the diagnostic characters.

Brachyauchenus varicosus (Platyphyllini) is here transferred to Stenoschema (Pleminiini) . The characters observed in the type specimens compare more with the diagnostic characteristics of this genus than Brachyauchenus . When comparing the other species described in Stenoschema , it is confirmed that this species is not synonymous with any of the other species already described and remains a valid taxon. Thus, Stenoschema has seven valid species, with a mainly Amazonian distribution, but also with some records from the Andes and Atlantic Forest ( Cigliano et al ., 2021 ). The habitus and other characters are typical of the taxa of the tribe Pleminiini , as mentioned by Braun (2012) , in a scrutiny of the Orthoptera Species File.
