Indotyphlidae
The Indotyphlidae are a family of caecilians ( Gymnophiona ) that is found in India, Africa, and on the larger Inner Islands of the Seychelles.
Features
Like all caecilians are the Indotyphlidae wormlike amphibians without limbs and with a sharply formed tail. From other amphibians crawl they differ by their imperfect stapes (one ossicles ), the inner row of teeth with bicuspid teeth in the lower jaw and the position of the eyes on the border between squamosal and Maxillopalatine. They are either oviparous (egg Legend) or viviparous ( ovoviviparous ). All are viviparous Indotyphlidae unbeschuppt and lack the secondary annuli. The annuli are circular folds of skin, through which the caecilians are curled and which in turn can be divided into primary, secondary and tertiary annuli.
Phylogenetically, they are defined as those caecilians, the rostratus as annulatus closer with Hypogeophis with Siphonops or Dermophis mexicanus are related.

System
Within the caecilians are the sister group of the Indotyphlidae a common clade of Dermophiidae and Siphonopidae, all three families stand together in a sister group relationship with a clade of Typhlonectidae and Caeciliidae. (See caecilians: Section taxonomy)
