Pratigi aristeui, a new Neotropical genus and species of Stenopodainae (Hemiptera: Heteroptera: Reduviidae)

Abstract

Pratigi aristeui gen. & sp. nov. (Hemiptera: Heteroptera: Reduviidae: Stenopodainae) is described based on a male from the state of Bahia, Brazil. Pratigi gen. nov. differs from all other New World genera by the conspicuously elongated clypeus and the subpentagonal shape of the head. Other diagnostic features of Pratigi gen. nov. include: body somewhat broad, about three times as long as maximum width, flattened dorsoventrally; postocular part of head with a ramose setigerous process posterolaterally; prosternum elongated behind fore coxae; fore femora strongly incrassate, fusiform; fore tibiae curved; all tibiae without fossula spongiosa; fore tarsi three-segmented. A revised key to New World Stenopodainae genera is presented.
