Interpretive Summary: Many parasitic wasps are beneficial to U.S. agriculture as biocontrol agents. This study identifies 12 species of a small family of parasitic wasps that parasitize longhorned beetles and other wood-boring beetles from northern South America. Some also may parasitize wood-boring wasps. Seven new species are described, and all species are described, illustrated, and separated in a key. A means for identification of these species will be useful for scientists involved in biological control and action agencies such as APHIS who are involved with prevention of introduced species into the United States.
Technical Abstract: Twelve species of Aulacidae, three Aulacus and nine Pristaulacus, are recorded from northern South America: Aulacus amazonicus (Roman), A. cephalus, n. sp., A. ochreus, n. sp., Pristaulacus absens, n. sp.,, A. colombianus, n. sp., P. femurrubrum, n. sp., P. haemorrhoidalis (Westwood), P. maculatus (Schletterer), P. punctatus, n. sp., P. ruficeps (Westwood), P. tridentatus, n. sp., and P. zonatipennis Roman. This study is based on recent collections from Colombia. Aulacus bicornutus Schletterer 1889 is a new synonym of Pristaulacus ruficeps (Westwood 1851). The species are described and illustrated and a key is given.
