چکیده
Thripenema fuscum n. sp., a parasite of the tobacco thrips, Frankliniella fusca, is described and illustrated from material collected from peanut (Arachis hypogaea) in Marianna, Florida. Thripenema fuscura can be distinguished from all other previously described Thripenema spp. by the dorsal curvature of the male and the presence of a stylet in the male. Highest parasitism rates of F. fusca by T. fuscum in peanuts were 51% in 1995 and 68% in 1996.
