We cloned and sequenced the rDNA internal transcribed spacer 2 (ITS2) of 4 species belonging to the neotropical Anopheles (Nyssorhynchus) albitarsis complex, that is, A. albitarsis; A. albitarsis B; Anopheles marajoara, a proven malaria vector; and Anopheles deaneorum, a suspected vector. Even though the ITS2 sequences of these species were very similar (≤1.17% divergence), we found differences suitable for species identification and intragenomic variation of possible consequence in phylogenetic reconstruction. Variation came from 2 microsatellite regions and a number of indels and base substitutions. The existence of partially correlated subsets of clones in A. albitarsis is hypothesized either to be separate rDNA loci or to be semi-independently evolving portions of a single rDNA locus. No differences were found between males and females, suggesting that similar rDNA arrays exist on both the X and Y chromosomes. In addition, highly variant clones, possibly pseudogenes, were found in A. marajoara from Venezuela.
