discussion
Remarks. The most similar species is Platytyphlops racovitzai, which is also known from the Antarctic. However, in P. racovitzai the carapace ridges have a tall, narrow hyaline margin, while in P. rossi the ridges are not tall and do not have a hyaline margin. Platytyphlops crosnieri is also similar to P. rossi; however, in P. rossi there is a ridge present on the pseudorostrum, while in P. crosnieri there is no ridge on the pseudorostrum.
