I do not see any indication of P. breitensteini with this specimen, but it is showing some unusual traits. The reddish colored eyes and single supraocular over each eye is not commonly seen in P. brongersmai. However, I don't see any other characteristics that would lead me to believe it was not. In my opinion this is definitely not a Malaysian specimen as it has the look of a Sumatran brongersmai.
