A new genus and species of apterous Doryctinae (Hymenoptera: Braconidae) from Costa Rica

Abstract

Doryctinae are one of the most diverse and species-rich subfamilies of the Braconidae. The subfamily is diagnosed by a row of spines on the foretibia, a flange on the propleuron above the forecoxa, the presence of an epicnemial carina and occipital carina (Marsh 2002), a double node near the apex of the dorsal valve of the ovipositor (Quicke et al., 1992), and a cyclostome mouth. Most species are thought to be idiobiont ectoparasitoids of wood-boring beetles but host records are rare and show a great deal of diversity. Some are known to be phytophagus on seeds, parasitoids of Embiidinae (Shaw & Edgerly 1985) and others attack wood boring lepidopterans or sawflies. Members of Psenobolus are thought to be inquilines of fig wasps (Ramirez & Marsh 1996). Marsh (1997) provided a key to the New World genera and Marsh (2002) included a key to the genera of Costa Rica.
