Abstract

The adult, pupa, and final-instar larva of Trichothaumalea elakalensis sp.nov. (Diptera: Thaumaleidae) are described and illustrated. This is the first record of this genus from eastern North America and first description of the immature stages. In addition, reinterpretation of the homologies of the male terminalia and preliminary observations on the male reproductive system of Thaumaleidae are presented and the phylogenetic implications upon the monophyly of the Chironomoidea are discussed.

Résumé

On trouvera ici la description illustrée de l’adulte, de la nymphe et de la larve de dernier stade de Trichothaumalea elakalensis sp.nov. (Diptera : Thaumaleidae). Il s’agit là de la première espèce du genre trouvée dans l’est de l’Amérique du Nord et la description des stades immatures de ce genre est inédite. Une nouvelle interprétation des homologies entre les genitalia mâles et des observations préliminaires du système reproducteur mâle des Thaumaleidae remettent en question le monophylétisme des Chironomoidea.
