Abstract

Trichomalopsis dubius (Ashmead) and Dibrachys cavus (Walker), pteromalid parasitoids of pupae of various muscoid flies, are reported for the first time from the hosts Musca domestica L. and Stomoxys calcitrans (L.) (Muscidae) associated with livestock manure in New York. Morphological descriptions of the male and female of both species are given, as are field and laboratory observations, biological notes and hosts summarized from the literature, and known geographic distribution. An existing illustrated key to pupal parasitoids of muscoid flies associated with livestock manure is modified to include T. dubius and D. cavus.
