Abstract Drosophila auraria and its sibling species, D. biauraria, D. triauraria, and D. quadraria are unique among Drosophila species in that their salivary gland chromosomes exhibit Balbiani rings. In this report we present a cytological map of D. auraria and information on the developmental profiles of its puffs and Balbiani rings. Information is presented on the existence of tandem inverted duplications involving the Balbiani ring regions and other regions of the chromosomes, and data are given concerning the puffing patterns of the duplicated bands. Possible homologies between puffs of D. melanogaster and D. auraria and certain differences between the two species in the developmental sequences of the active loci are discussed.
