Canonical variate, eigenshape, relative warps, and thin plate spline analyses were applied to the ostracods Cyamocytheridea? sp., Digmocythere omarai Cronin and Khalifa and D. ismaili Bassiouni. These analyses suggest that Cyamocytheridea? sp. is more similar to D. ismaili than D. omarai and, according to its taxonomy, should be described in a new species: Digmocythere cronini. The morphometric analyses support the suggestion of Boukhary et al. (1982) in placing D. omarai Cronin and Khalifa as the ancestor of D. ismaili (Bassiouni).
