We met with A. albitarsis, A. darlingi, A. triannulatus, A. oswaldoi, A. noroestensis, A. pessoai and A. intermedius in Campos city, Rio de Janeiro State; indoors catches: darlingi, albitarsis and triannulatus, the last in small numbers in buildings where men and domestic animals cohabitate; as malaria vectors: darlingi (6.8% oocyst-, 4% sporozoit- indices) and albitarsis (2% oocyst, 0% sporozoit-indices). We are reporting a short study of the breeding places and pointing out that darlingi larvae breed in greater water collections, pond and channels as well as in small pools and drainage ditches under open sky. We are presenting a revision of the literature concerned with darlingi as a vector and with the ecology of their larvae.
