Formerly identified as S. heterorhinos(Bleeker), type locality Ambon, Indonesia, it is separated from this species by its more evenly dark-barred color pattern and having a snout length greater instead of less than the eye diameter. It is most similar in color to an undescribed species from the islands of Micronesia that has also been misidentified as S. heterorhinos, differing mainly by

its lower lateral-line scale count of 98–115 and 50 or 51 vertebrae. S. dori was also differentiated from S. multifasciatus (Kaup), described from one specimen from India, and S. nigrostriolatus (Steindachner and Kner) from Fiji by color and meristics (Ref. 79000).
