Cophixalus rajampatensis is a 2015 newly described species of frogs from the subfamily of Papuan narrow-mouth frogs (Asterophryinae) within the family of narrow-mouth frogs . So far it is only known from the islands of Batanta and Waigeo . These are located in the Raja Ampat archipelago , which belongs to the Indonesian part of New Guinea .

features

With a head-trunk length between 17.6 and 19.5 millimeters in males, Cophixalus rajampatensis is one of the smaller species of the genus Cophixalus . The legs are not particularly long, but reach about half the length of the head and torso. The fourth toe is the longest, the third toe is longer than the fifth. The adhesive discs on the fingers are much smaller than those on the toes.

The back color of the frog is bronze, the skin is smooth and shows only a few irregularly scattered warts on the flanks, which appear dark brown at the base and lighter to pink at the tip. The undersides of the extremities are cream-colored, as is the abdomen. Irregular brown spots can be seen on it. The anal region is blackish in color. A cream-colored stripe runs from the snout along the canthus rostralis to behind the eye. A dark brown stripe begins there and runs along the back. A dark brown to blackish “mask” covers the skin region between the nose and eyes and the throat up to the base of the upper arms.

Way of life

The frogs live in the rainforest, even if it is affected to a lesser extent by deforestation. After heavy rainfall, the males sit on leaves up to one meter above the ground and signal their presence to the females with their calls. Your call is a sequence of two to five tones that produce a beeping sound at a frequency of 3.7 kHz. The calls are repeated every few seconds.

Research history

The type specimen of Cophixalus rajampatensis discovered on the island of Waigeo in the Raja-Ampat archipelago in early June 2005 was described in 2015 by Rainer Günther from the Museum für Naturkunde Berlin and his Australian and Indonesian colleagues. The same work describes the species Cophixalus salawatiensis , which was also discovered in 2005 on the neighboring island of Salawati . Despite the proximity of the islands to each other, there is no overlap in the range of the two species. The species name rajampatensis refers to the origin of the frog from the Raja Ampat archipelago.
