New distribution records of Cerambycinae (Coleoptera: Cerambycidae) in the Brazilian Amazon

We present new records for 42 species of longhorn beetles (Cerambycinae) in the Amazon Region, including the first report of Tomopteropsis cerdai Peñaherrera-Leiva & Tavakilian, 2003 in Brazil (Rondônia). New state records are provided for Amapá (one species), Amazonas (six species), Pará (one species), Rondônia (seven species), Roraima (13 species), and Acre (17 species). The new records expand the known distribution of the species and illustrate the important role played by inventories like the thematic network "Biodiversidade de Insetos na Amazônia" (Rede BIA) in helping us understand the biodiversity of the Amazon region.(AU)

Validation of Eclipta dendensis Nascimento & Santos-Silva, 2017 (nomen nudum) (Coleoptera, Cerambycidae, Cerambycinae, Rhinotragini)

ABSTRACT Eclipta dendensis Nascimento & Santos Silva, 2017 (nomen nudum) is validated. The Neotropical Eclipta Bates, 1873, together with five other genera, composes a generic complex in Rhinotragini, which were previously allocated in Ommata White, 1855. In Brazil, many species of Eclipta are distributed in the Amazon and Atlantic forest regions. In this work, Eclipta dendensis sp. nov. from the Brazilian Atlantic Forest is described and illustrated.
