See account by Iskandar, 1998, Amph. Java Bali: 28-29, who noted that the species has not been recollected since the types and this may mean that the specimens did not originate on that island or that they have been extirpated there.

Evol., 63: 714-723, commented on the distinctiveness of this lineage (as Ichthyophis cf. hypocyaneus) from other members of this clade (e.g., their Ichthyophis cf. kohtaoensis, Ichthyophis cf. supachaii, and Ichthyophis unnamed species 1).
