Excerpt: A number of apparently related species, including the three which are newly described in this paper, belong to the large binotata group of Dobzhansky (1941). It has been found necessary to re-examine this group and to divide it into smaller, more homogeneous species clusters. These new species clusters may indicate more clearly the relationships of the species involved.
