[1][2] The specific name grylloides, from Latin gryllus ("cricket") and Greek suffix -oides ("resembles"), alludes to its cricket-like, high-pitched advertisement call.

Skin of the upper surfaces bear scattered low, rounded tubercules; the venter is smooth.

The holotype, as seen at night, had black dorsal medial area, grading laterally to medium brown, and contrasting with the orangish-brown snout, thighs, and posterior of the dorsum.

[1] The male advertisement call is high-pitched, with dominant frequency of 4845–5115 Hz, giving it a cricket-like sound.

[1] Given the availability of suitable habitat, this species has probably a broad distribution along the northern slopes of the New Guinea Highlands.
