Belongs within: Gymnophiona.

The Caeciliidae are a pantropical group of caecilians in which a true tail is absent (Frost et al. 2006).

Characters (from Frost et al. 2006): Tail absent; premaxillae and nasal bones fused; septomaxillae usually reduced or absent; pterygoid absent; basiptergygoid process usually large; fused third and fourth ceratobranchials greatly expanded; vent usually circular or transverse, not longitudinally oriented.
