Simuliidae (Diptera: Culicomorpha) in Brazil: VI - Simulium (Psaroniocompsa) siolii sp.n., Simulium (P.) lourencoi sp.n., and Simulium (P.) damascenoi sp.n.

Abstract

Three new species of the subgenus Simulium (Psaroniocompsa) Enderlein are described: S.(P.) siolii, found in the Hydrogeological Provinces of the Central Shield and West-Center (in the subprovinces of Chapada dos Parecis and Upper Paraguay), S.(P.) lourencoi, found in the Hydrogeological Provinces of the Central Shield and the Parnaiba, and S.(P.) damascenoi, found in the Hydrogeological Provinces of Amazonas and the Northern Shield. These species have some convergent characteristics during the larval stage with the subgenera Edwardsellum (Ethiopian) and Byssodon (Ethiopian and Holoarctic). This is the first time that these convergent characteristics have been observed in the neotropical region. Differential keys are presented for larvae and pupae of the subgenus Psaroniocompsa the pupae of which have 4 terminal gill filaments.
