RESUMO
Ultraestrutura dos ovos de duas espécies de Anopheles (Anopheles) Meigen, 1818 (Diptera, Culicidae). A ultraestrutura dos ovos de duas espécies morfologicamente semelhantes da Série Arribalzagia, Anopheles (A.) costai Fonseca & Ramos, 1939 and A. (A.) mediopunctatus (Lutz, 1903), é descrita e ilustrada usando-se microscopia eletrônica de varredura.. Embora sejam morfologicamente semelhantes nos estádios adulto, estruturas da genitalia masculina, larva de quarto estádio e pupa, os ovos destas duas especies são distintos. Os ovos de A. costai e A. mediopunctatus são comparados com os de A. forattinii Wilkerson & Sallum, 1999. Apresenta-se a ilustração incompleta do ovo de A. forattinii para comparação com os ovos das outras duas espécies.

Anopheles galvaoi, a member of the subgenus Nyssorhynchus, is redescribed based on morphological characters of the adults male and female, fourth-instar larva and pupa. Female, male genitalia, larval and pupal stages are illustrated. Data about medical importance, bionomics, and distribution are given based on literature records. Adult female of An. galvaoi can be easily misidentified as An. benarrochi Gabaldón and An. aquasalis Curry. A few characters are indicated for identifying female and immatures of An. galvaoi. Phylogenetic relationships among An. galvaoi and six other species of the Oswaldoi Subgroup are estimated using COII mtDNA and ITS2 rDNA gene sequences. Lectotype of An. galvaoi, an adult female from Rio Branco, State of Acre, is invalidated

The ultrastructure of the eggs of Anopheles (Nyssorhynchus) galvaoi Causey, Deane, and Deane and Anopheles (Nyssorhynchus) evansae (Brethes) are described and illustrated with scanning electron micrographs. The eggs of these species are similar to those of Anopheles (Nyssorhynchus) aquasalis Curry, Anopheles (Nyssorhynchus) oswaldoi (Peryassu), and Anopheles (Nyssorhynchus) konderi Galvão and Damasceno in having floats long, widely joined posteriorly on the dorsal surface, the frill encircling the anterior end of the egg, and the crown absent. A few distinctive characters to distinguish An. evansae from An. galvaoi are given.
