| Summary: | Indies and used in cross-mating experiments. Larvae from the cross, Mexico female 3 Grenada male, died in the third instar. However, adult progeny were obtained from the reciprocal cross Grenada female 3 Mexico male. These hybrid males had testes with apparently normal appearance but some without viable sperm. Polytene chromosomes obtained from hybrid females exhibited extensive asynapsis of the X chromosomes. Previously undescribed fixed inversion differences between the two populations were noted on the X chromosome. It is concluded that the two populations belong to different species. The Grenada population is designated An. pseudopunctipennis species C, since it is the third taxon recognized in this species complex. Anopheles pseudopunctipennis s.l. Theobald is one of the main malaria vector species of the American region.1 It also has one of the longest latitudinal distributions of any malaria vector in the new world with a range that includes the Ne-arctic Region of Kansas in the United States to northern Chile and Argentina in the Neotropics.2,3 Anopheles pseu-dopunctipennis was first described by Theobald in 19014 from specimens collected on the island of Grenada in the |
