Abstract
A new species of East African caeciliid caecilian, Boulengerula niedeni spec. nov. (Amphibia: Gymnophiona) is described based on a series of 11 specimens from Sagalla Hill, an isolated mountain block of the Taita Hills in southern Kenya. It differs from all other Boulengerula, except B. taitanus (Loveridge), in being pigmented with whitish marked annular grooves and from B. taitanus by its distinctive brownish colouration, an exposed sphenethmoid, a higher mean number of annuli and vertebrae, and different phallus morphology.References
