First records of Acrotaphus fuscipennis (Cresson) and of A. tibialis (Cameron) from the United States (Hymenoptera: Ichneumonidae)

J. Brambila, C. C. Porter

Abstract


Acrotaphus fuscipennis (Cresson), distinctive because of its black wings and bright red body, is recorded for the first time from the United States. It was reared from araneid spiders collected in Florida, which constitutes the first host record for this species. Acrotaphus tibialis (Cameron), collected in Texas, is also recorded for the first time in the United States. New U.S. localities are given for A. wiltii (Cresson). A key is provided for the identification of the three species of Acrotaphus in United States. The adults of all three species and the cocoon of Acrotaphus fuscipennis are illustrated.
