Revision of North American Aleiodes (Part 9): the pallidator (Thunberg) species-group with description of two new species (Hymenoptera: Braconidae, Rogadinae).

The Aleiodes pallidator species-group is defined, and an identification key is provided for the five species known to occur in the U.S.A. and Canada. Two new species are described: Aleiodes martini Shaw and Marsh, from Florida, and A. xanthoclypeus Shaw and Marsh, known from Canada and Wisconsin, and reared from Lymantriidae species including Dasychira plagiata (Walker) and Olene grisefacta (a new host record for the genus Aleiodes). Five species are illustrated, and their host associations are summarized.
