Remarks. Platytyphlops grimaldii is most similar to P. peringueyi, but can be distinguished by the pattern of ridges on the carapace. In P. peringueyi the posterior dorsal pair of ridges are produced as a blunt tooth, while in P. grimaldii the posterior dorsal pair of ridges are half the length of the carapace, and not produced as a blunt tooth. In addition, P. peringueyi is known from South Africa, while P. grimaldii is known from the North Atlantic.
