    Abstract:
    The egg of Anopheles nuneztovari is described from scanning electron micrographs of specimens collected from western Venezuela. Morphometric measurements of egg samples from 3 localities in Venezuela, one in Suriname, and 4 in Brazil are compared and relationships analyzed by multivariate statistics. Morphological characters were similar in 2 geographical groups, one Venezuelan and the other Amazonian, that were distinguishable on the basis of differences in size and density of tubercles in the anterior deck region and area of pores in the dorsal plastron. Eggs from western Brazil did not cluster with other Amazonian collections. The distinction of Venezuelan from Amazonian eggs of An. nuneztovari is consistent with chromosomal, ecologic, and molecular evidence for regional genetic differentiation in this species.
