Cophixalus salawatiensis 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 island of Salawati in the Raja Ampat archipelago . This group of islands belongs to the Indonesian part of New Guinea .

features

The head-trunk length of Cophixalus salawatiensis is between 19.6 and 22.5 millimeters in males. 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. There are no webbed feet between the frog's fingers and toes . The adhesive discs on the fingers are the same size as on the toes or even larger in this type.

The frog's snout is pointed and appears slightly protruding in profile. The back color is beige to orange with gray spots mainly on the flanks. The skin is smooth and shows irregular tubercles that may be arranged in dorsolateral rows. 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. A whitish stripe runs from the snout along the canthus rostralis to behind the eye. A short, dark brown stripe begins there and extends backwards. This delimits a round, cream-colored area behind the eye that extends to the base of the upper arms. Noticeable is an orange spot in each of the upper arms. A gray-brown "mask" in living specimens covers the skin region from the snout and below the eye to the round, light spot. The throat is gray.

Way of life

After heavy rainfall, the males climb leaves at a height of 30 centimeters to 1.5 meters above the ground. Their call is a sequence of six to eight tones which, due to their high frequency of 2.9 kHz, result in a beeping sound. The calls are repeated at intervals of up to one minute. A hermaphroditic specimen was also found that behaved like the other males and shouted for females from a leaf, but also contained eggs in various stages of development.

Research history

The type specimen of Cophixalus salawatiensis discovered on the island of Salawati in the Raja Ampat archipelago at the end of June 2005 was described in 2015 by Rainer Günther from the Museum für Naturkunde Berlin and his Australian and Indonesian colleagues. In the same work, the species Cophixalus rajampatensis , which was also discovered in 2005 on the neighboring islands of Batanta and Waigeo , was described. Despite the proximity of the islands to each other, there is no overlap in the range of the two species. This is probably due to the different geological development of different parts of the archipelago .
