features

The adult animals reached a total length between 100 and 139 mm. The adult males had a standard length of 44 to 52 mm, the adult females a standard length of 41 to 62 mm. The tail length took up 59 to 66 percent, the head width 7.5 to 9.5 percent, the leg length 7.8 to 10.1 percent and the foot width 1.8 to 2.4 percent of the total length. The body was very slim and the legs were very short. The head was very narrow, the muzzle was short and rounded. Eyes, hands and feet were very small. There were 14 to 43 teeth in the upper jaw. The number of teeth on the ploughshare was 10 to 23. The trunk was segmented with 12½ to 15 rib furrows between the flattened limbs. The top was gray-black, the bottom gray.

Habitat and way of life

Oedipina paucidentata inhabited moist, montane rainforests at altitudes of up to 2286 m. He had a secret way of life that was probably partly adapted to digging. The smallest young animal found had a standard length of 28 mm.

status

Oedipina paucidentata is only known from the type collection that Edward Harrison Taylor brought together in 1951 and 1952 near Cartago in the extreme northern Cordillera de Talamanca in the central region of Costa Rica. The IUCN classifies it in the “critically endangered” category.
