Chaetophractus vellerosus present cylindrical ovaries with rounded extremities, a ventral parenchymatous zone "cortex" and a dorsal vascular one "medulla? with typical structure. In D. hybridus they are bean-shaped, the concavity corresponding to the parenchymatous zone and the convexity to the vascular zone. The presence of polyovular follicles in C. vellerosus and Z. pichiy is usual. Structures associated with the ovary (epoophoron, rete ovarii) are similar in the three species. While the features of the ovaries of C. vellerosus and Z. pichiy are comparable with those of C. villosus (Desmarest the ones of D. hybridus are similar to those of D. novemcinctus Linné, 1758.
