in 1924. Common name Kopstein's callulops frog has been coined for this species.

Description

The type series consists of two adult males measuring and an adult female measuring in snout–vent length. The overall appearance is stocky. The head is somewhat wider than it is long. The snout is rounded but slightly protruding. The tympanum is distinct. The finger and toe tips bear small discs; webbing is absent. Skin is smooth. The upper parts are dark brown. There are two eye spots; other markings are vague. The underside is dirty gray-brown, with diffuse, light gray spots.

Habitat and conservation

''Callulops kopsteini'' has not been recorded after it was first collected (i.e., 1924). It presumably occurs in lowland forest. Development is assumed to be direct (i.e., there is no free-living larval stage). This species is likely to be threatened by extensive logging taking place on Sanana Island. However, there is no recent information on its status.
