 Phylogenetic analysis of Indian caecilians | AmphibiaTree
As judged by bootstrap proportions, decay indices, and leaf stabilities, well-supported relationships of the Indian caecilians are recovered from the alignment.
The data (1) corroborate the hypothesis, based on morphology, that the Uraeotyphlidae and Ichthyophiidae are sister taxa, (2) recover a monophyletic Ichthyophiidae, including Indian and South East Asian representatives, and (3) place the Indian caeciliid Gegeneophis ramaswamii as the sister group of the caeciliid caecilians of the Seychelles.
Rough estimates of divergence times suggest an origin of the Uraeotyphlidae and Ichthyophiidae while India was isolated from Laurasia and Africa and are most consistent with an Indian origin of these families and subsequent dispersal of ichthyophiids into South East Asia.

  192ABSTRACT   (Site not responding. Last check: 2007-10-27)
The presence of an endo-nuclear canal containing a perforatorium is a plesiomorphic feature of caecilian spermatozoa that is shared with urodeles, some basal anurans, sarcopterygian fish, and some amniotes.
Spermatozoal synapomorphies are identified for 1) the Uraeotyphlidae and Ichthyophiidae, and 2) the Caeciliidae and Typhlonectidae, suggesting that the members of each pair of families are more closely related to each other than to other caecilians.
Although caecilian spermatozoa exhibit the clear amphibian synapomorphy of the unilateral location of the undulating membrane and its axial fiber, they have no apomorphic characters that suggest a closer relationship to either the Urodela or Anura.

Evol., 23: 401-407, provided evidence that Uraeotyphlidae and Ichthyophiidae were sister taxa.
Monogr., 3: 31, suggested that Caudacaecilia and Ichthyophis might both be polyphyletic inasmuch as they are based solely on single characters of known variability.
Sci., 269: 1563-1569, suggested that the Ichthyophiidae is paraphyletic with respect to the Uraeotyphlidae.
