Abstract: 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.
