Werneria tandyi, also known as Tandy's torrent toad or Tandy's smalltongue toad, is a species of toad in the family Bufonidae. It is endemic to western Cameroon and known from Mount Manengouba and from the Rumpi Hills. The specific name tandyi honours Robert Mills Tandy, biologist, herpetologist, and wildlife photographer.
Werneria tandyi is a relatively slender-bodied Werneria. Males grow to 35 mm (1.4 in) and females to 41 mm (1.6 in) in snout–vent length. The head is straight and pointed. Parotoid glands and tympani are absent. The toes have traces of webbing. The back is dark chocolate-brown, while the flanks are very dark brown to black and separated from the back by thin, white dorsolateral lines that are well-delineated. The venter is clear brown to yellowish gray with tiny white or yellow spots.
