Peruzuphium n. gen. giachinoi new species of the tribe Zuphiini from Peru, with notes on Metaxidius brunnipennis Chaudoir

Peruzuphium n. gen. giachinoi n. sp., a notable new species of the tribe Zuphiini from Peru with uncertain affinities, is described. It is the first zuphiine species recorded from Peru and is compared in particular to Metaxidius brunnipennis Chaudoir, another rare South American zuphiine species with uncertain affinities, which is discussed and illustrated too. A key to all genera of South American Zuphiini is finally provided.
