Abstract

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.

Resumen:
Acrotaphus fuscipennis (Cresson), especie notable por sus alas negras y cuerpo rojo intenso, se cita por primera vez de los Estados Unidos. Fué obtenida de arañas de la familia Araneidae (género Neoscona) colectadas en Florida, lo que constituye el primer registro de los hospederos de esta especie. Acrotaphus tibialis (Cameron), que fué colectada en Texas, también se cita por primera vez de los Estados Unidos. Se dan nuevas localidades en los Estados Unidos para Acrotaphus wiltii (Cresson). Se presenta una clave para la identificación de las tres especies de Acrotaphus para los Estados Unidos. Se ilustran los adultos de las tres especies y el capullo de A. fuscipennis.
