HYLODIDAE - CROSSODACTYLID FROGS
A single species recorded in Paraguay. The Crossodactylid frogs were, until recently, treated as a subfamily of a larger Leptodactylidae. They exhibit 8 free procoelous, holochordal presacral vertebrae. Ribs are absent. The urostyle is free with two condyles and the pectoral girdle arciferal. Sternal elements are all cartilaginous. The clavicle does not overlie the scapular. Palatines are present. Teeth present on the maxilla and premaxilla, those on the former being pointed and pedicellate. Astralagus and calcaneum are fused only at the ends. Toes fringed. No intercalary phalanges. The sartorius is a separate and distinct muscle. Eggs deposited on land or in water. Aquatic larvae with umbrella mouth. 2n=26.
