[email protected] 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 elonga- ted 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, fl attened 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. Key words. Heteroptera, Reduviidae, Stenopodainae, assassin bugs, Attalea funi- fera, Brazil, Neotropical Region Introduction Approximately 113 genera belonging to the assassin bug subfamily Stenopodainae (Hemi- ptera: Heteroptera: Reduviidae) are currently considered as valid, with the majority of them inhabiting the tropics (MALDONADO 1990, SCHUH & SLATER 1995), where the species diversity is greatest in Africa and America (GIACCHI 1987), particularly in the Amazon basin of South America (BÉRENGER 2001).
