[1][2][3] The specific name tandyi honours Robert Mills Tandy, biologist, herpetologist, and wildlife photographer.

The venter is clear brown to yellowish gray with tiny white or yellow spots.

[5][3] Werneria tandyi lives by fast-flowing streams in submontane forest and degraded secondary habitats at elevations of 1,000–1,750 m (3,280–5,740 ft) above sea level.

Several individuals have been found clustered together on rocks in the splash zone of waterfalls during the breeding season.

[1][3] Previously, Werneria tandyi was common on Mount Manengouba, but it has not been observed there after 2010.
