Southern Caecilian

Dermophis gracilior is a moderate-sized caecilian measuring 255–387 mm (10.0–15.2 in) in total length. It has 91–117 primary and 65–96 secondary annuli. The body is somewhat robust (length 23 to 34 times the body width). The upper surface is lead-gray in color, whereas the lower one is cream with dark mottling, or largely gray to dull black. The annular grooves are similarly colored as the adjacent areas.

Dermophis gracilior occurs in humid lowland, premontane, and montane forests at elevations 404–2,000 m (1,325–6,562 ft) above sea level. It is a subterranean species that can be found under logs and surface debris. It is probably viviparous. D. gracilior is a poorly known species known from few specimens. Deforestation might be a threat to it. It is found in the La Amistad International Park (Panama) and in the Las Cruces Biological Station (Costa Rica).
