A surprising new fightless stag beetle (Coleoptera: Lucanidae: Lucaninae) genus and species from Peru

A new beetle genus was found from the lucanid tribe Chiasognathini (Coleoptera: Lucanidae: Lucaninae) in the Peruvian high plateaus. Here we first describe Orotrupes Amorim and Paulsen, new genus, and its type species, O. asenjoi Amorim and Grossi, new species, compare it to other species of the tribe and speculate on the biogeographical history of the new taxa. Additionally, we provide a new generic key to the tribe and a map to chiasognathine beetles found in Peru.
