Abstract

Therion Curtis currently includes 26 valid species, but only three species are known from South America, with no species known from Peru. The genus is reported for the first time from Peru and two new species are described: T. bifidus sp. nov. and T. blancasi sp. nov.. Illustrations and diagnoses for all South American species is presented together with a key for the Neotropical species.
