Abstract:
We describe the first case of dicephalism in a caecilian larva, Ichthyophis bannanicus, from southeastern Guangxi, China. The two heads of the larva are united at the anterior one-third of the body. It is measured as: body mass 0.6 g, total length 42.4 mm, body width at middle 5.4 mm, head length 2.1 mm, head width 2.5 mm, snout length 1.5 mm, internarial distance 0.9 mm, and interorbital distance 1.7 mm. Compared to normal conspecific larvae, it is smaller except for the internarial distance, body mass and body width at midbody.
