A new species of Pelidnocoris (Hemiptera: Heteroptera: Pentatomidae) from the Brazilian Atlantic Forest

In this work a new species, Pelidnocoris paradisicola sp. nov., of the genus Pelidnocoris Stål, 1868 (Hemiptera: Heteroptera: Pentatomoidea: Pentatomidae: Discocephalinae) is described from the southeastern Brazilian state of Minas Gerais. An up-to-date diagnosis of the genus and its species is provided, comparing them with similar-looking Discocephalini genera. This is the first record of the genus for the Atlantic Forest, in southeastern South America, and increases the number of species in Pelidnocoris to four. The other species of Pelidnocoris are distributed from southern North America to northern South America, with records from Mexico, Colombia, Costa Rica, Panama, and northern Brazil. Photographs from the citizen science platform iNaturalist indicate the genus is also distributed in the state of São Paulo, Brazil, as well as in Belize, Ecuador and Peru, all representing new records. An identification key to the species of the genus is included, based on characters of general morphology and external male genitalia. Identification of the genus and its species from photographs in online repositories and databases is addressed.
