The Grandisoniidae are a family of common caecilians found in Africa, Seychelles and India. Like other caecilians, they superficially resemble worms or snakes. The family was formerly known as Indotyphlidae.
The genera in this family were originally placed in family Caeciliidae. In 2011, the genera Gegeneophis, Grandisonia, Hypogeophis, Idiocranium, Indotyphlus, Praslinia and Sylvacaecilia were segregated into family Indotyphlidae, named after the tribe Indotyphlini, which was used by Lescure et al (1986) for the Indian genera, Gegeneophis and Indotyphlus.[1] However, it was later pointed out that the name Grandisoniidae is the appropriate family-group name because, according to rules of the Nomenclatural Code, a name published at higher rank, Grandisoniinae, has precedence over a name of lower rank published in the same work, Indotyphlini.[2]
