Chromosomal differences among species of Anopheles mosquitoes. Mosq Syst

ABSTRACT. All of the anopheline species thus far studied have distinctive cy-togenetic features which permit identification to species. In some cases the cytogenetic differences are the only sure methods of distinguishing among mem-bers of a complex of sibling species. Easily seen cytogenetic differences are found in the X-chromosomes and in the autosomes, which often contain character-istic and unique inversions. Many of the banding pattern similarities occur in distantly related species and may extend to subgeneric levels. Most thoroughly studied thus far include: AnopheZes macdipennis (nearctic and palearctic); sub-genus Ce ZZia, including the An. gambiae complex and several other species groups; subgenus Ste thomyia; and subgenus.Uyss~rhynchus~ The Anophe Zes macdipennis complex. The cytogenetic approach to anopheline identification begins with the Ano-pheles maculipennis Meigen complex and with the classical morphological, ecolog-ical, physiological and hybridization studies of'Falleroni, Missiroli, Hackett, Bates and their colleagues. These studies ultimately culminated in the recog
