CommentSynonymy: has been considered as synonym of subspecies of X. piscator.

Although typical X. sanctijohannis differ from typical X. piscator, there are several intermediate morphs. It differs from X. piscator especially by a patternless body and a slightly higher number of ventral scales. However, the dark patternless body may be an adaptation to the ecological conditions of high mountains rather a taxonomical difference [VOGEL & DAVID 2006]. 
EtymologyNamed after Colonel Sir Oliver Beauchamp Coventry St. John (1837- 1891) who worked for the Bengal Army ofthe Honourable East India Company (1856) and who provided the types to Boulenger. Note his latinized name, “sanctijohannis”.
