Diagnosis | Diagnosis: Juveniles of Rhabdophis callistus can be identified almost exclusively on the basis of their striking colour and pattern. Since pictures of adult specimens are not available, for them we have to rely upon the above description of body characteristics and the head and body scales counts. Further, the 21 mid-body scale rows distinguish both R. callistus and R. chrysargoides from the doubtful Sulawesi species R. chrysargos (19 scale rows) and R. subminiatus subminiatus (19, rarely 17 rows). Juveniles of Rhabdophis callistus may be confused with juveniles of Rhabdophis chrysargoides, which have more or less the same pattern, but different colours. The most striking differences are in the vertebral band (greenish-olive in R. callistus, pink-orange in R. chrysargoides), the yellow longitudinal band beneath the dark band on the sides (present in R. callistus, absent in R. chrysargoides) and the two black longitudinal bands on the belly (present in R. callistus, present or absent in R. chrysargoides).

Comment | Some species of this genus are venomous although we do not have information about this particular species. Synonymy: Boulenger 1897: 219 thought that Tropidonotus callistus “is nothing but the young of T. chrysargoides” (see description), |
