Chikilidae

4 species in 1 genus

Commonly Called Northeast Indian Caecilians

This family was recently described in 2012 (Kamei et al) after extensive survey efforts in the Northeast India. A total of 1177 person hours were dedicated in the discovery of the caecilian Chikila fulleri, the first described species in the new family Chikilidae. From molecular phylogenetic analyses (both mitogenomic and nuclear DNA) and comparative cranial anatomy, they determined chikilids were more closely related to the African family Herpelidae than Indotyphlidae, diverging about 140 ± ca 20 Ma. Further, they propose this family represents an ancient radiation in wet tropical forests and thus evidence for the persistence of Cretaceous Period habitat in the northeastern India region.
