Abstract

Two new nematodes of the family Tetradonematidae, parasitic in aquatic dipterous insects in Louisiana, are presented. Corethrellonema grandispiculosum n. gen., n. sp., from the chaoborid fly, Corethrella brakeleyi Coquillett, and Aproctonema chapmani n. sp., from the sand fly, Culicoides arboricola Root and Hoffman, are described and illustrated. The biology and life histories of these nematodes show that the adults occur in the last larval instar of the insect host. The adult nematodes mate in the body cavity of the insect, and later the female nematode, replete with eggs, exits from the larval fly causing the death of the insect. Male nematodes usually remain in the insect cadaver.
