ABSTRACT
Two blackfly species Simulium (Cerqueirellum) oyapockense Floch & Abonnenc and S. (Hemicnetha) seriatum Knab are recorded from Argentina, representing the most southern register for both species. S. oyapockense is a species epidemiologically very important, as a vector of onchocerciasis in the Amazonian focus. Both species are described and illustrated and their distribution are reported, in similarity to others like S. roraimense Nunes de Mello and S. ganalesense Vargas et al. in reference to S. oyapockense and S. mexicanum Bellardi similar to S. seriatum are discussed.

Simulium (Pternaspatha) diamantinum n. sp. is described from females, males, pupae and larvae, collected at Mendoza, San Juan and Neuquen. Some specimens of this species from Laguna del Diamante were included before by Wygodzinsky and Coscarón (1967) in S. strigidorsum Enderlein. The new species is compared with closely related species of the S. (Pternaspatha) "nigristrigatum group". The following synonym is stablished: Simulium (Pternaspatha) bachmanni Wygodzinsky & Coscarón = Simulium (Pternaspatha) nigristrigatum (Enderlein).
