Ichthyophis biangularis

Ichthyophis biangularis, the angular caecilian or Metang caecilian, is a species of amphibian in the family Ichthyophiidae endemic to Borneo (Malaysia): it is only known from its type locality, Mount Matang in Sarawak, where the holotype was collected in 1872 by Alfred Hart Everett. New specimens were collected from the type locality only in 2009. In addition, one larval sample was collected from the same region and identified as likely Ichthyophis biangularis using genetic methods.

This is a little known species. It is presumed to inhabit tropical moist forests.
