The eggs of Anopheles galvaoi and Anopheles evansae, two species of the subgenus Nyssorhynchus.
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.
