[1][3] The specific name stictogaster is derived from the Greek stictos (="spotted") and gaster (="belly").

[1][3] Callulops stictogaster is a relatively large species that can reach 80 mm (3.1 in) in snout–vent length.

[2] Callulops stictogaster occurs in hill and montane rainforests at elevations of 1,400–2,580 m (4,590–8,460 ft) above sea level, often in steep terrain.

It is not a common species but can nevertheless occur in large numbers in suitable habitat.

It is not exposed to significant threats, although it is used as pig feed in the Chimbu Province.
