Rhinatrematidae, the family of Neotropical tailed caecilians or beaked caecilians, are found in the equatorial countries of South America.
They are usually regarded as the most primitive of the caecilian families, with numerous characteristics lacking in the other groups. For example, they still possess tails, and their mouths are not recessed on the underside of their heads. They lay their eggs in cavities in the soil. The larvae have external gills, and live in seepage areas until they metamorphose. The adults live in moist soil and leaf litter.[1]
Taxonomy
The nine species in two genera are:
- Genus Epicrionops - beaked caecilians
- E. bicolor - two-coloured caecilian (Peru, Ecuador, Venezuela, and Colombia)
- E. columbianus - El Tambo caecilian (Colombia)
- E. lativittatus - eastern Peru caecilian (Peru)
- E. marmoratus - marbled caecilian (Ecuador)
- E. niger - black caecilian (Guyana, Venezuela, and possibly Brazil)
- E. parkeri - Parker's caecilian (Colombia)
- E. peruvianus - Marcapata Valley caecilian (Peru)
- E. petersi - Peters' caecilian (Ecuador, Peru, and possibly Brazil and Colombia)
- Genus Rhinatrema
- R. bivittatum - two-lined caecilian (Brazil, French Guiana, Guyana, and Suriname)
- R. shiv - Shiv’s rhinatrema (Guyana)[2]
