Records from Equatorial Guinea and Gabon are uncertain, possibly belonging to Petropedetes euskircheni.

[2][3] P. parkeri is named after Hampton Wildman Parker, a British zoologist and herpetologist from the Natural History Museum, London.

The femora and lower legs have large darker spots divided by thin, bright coloured transversal bars.

[3] Information on the ecology of Petropedetes parkeri suffers from uncertain species identifications.

It appears to be a forest dweller, although during the breeding season, adults aggregate on humid rocky surfaces near torrents.
