Intraspecific variation of second internal transcribed spacer of nuclear ribosomal DNA among populations of Anopheles (Kerteszia) cruzii (Diptera: Culicidae).

Anopheline species of the subgenus Kerteszia, including Anopheles (Kerteszia) cruzii Dyar & Knab (Diptera: Culicidae), are bromeliad-malaria vectors in the Atlantic rain forest of Brazil. Morphological, genetic, and molecular polymorphisms among different populations of An. cruzii have been reported, and it has been suggested that this taxon includes a complex of cryptic species.
