Description

The type series of ''C. kopsteini'' consists of two adult males measuring in snout-to-vent length (SVL) and an adult female measuring SVL. 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. The 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

''C. 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.
