Bryophryne gymnotis is in Peru occurring Froschlurchart from the family craugastoridae . The specific epithet is based on the Greek adjective "γυμνός" ( gymnos = naked) and the Greek noun "Ὦτος" ( otos = ear). This name refers to a characteristic of the species that is currently the only member of the genus with an eardrum .
features
The head-torso length (SVL) of Bryophryne gymnotis varies in a range between 16.0 and 22.2 millimeters in females and between 16.7 and 19.3 millimeters in males. The skin is mostly smooth. The back color varies from red-brown to gray-brown to purple-brown. The head is narrower than the body, the muzzle short and round. Typical of the species is a narrow yellowish stripe that extends along the middle of the back. There are dark brown spots on both sides of the head. The underside is dark gray-brown and has many small white spots. The relatively short extremities are brown-gray to red-brown and slightly dark marbled. Your front feet have four fingers and the back feet have five toes. With a length of about five millimeters, the second toe is noticeably long. A sound bladder and eardrum are present. Young animals show dark brown spots on the head and body, the yellow stripe on the back is hinted at. The iris shimmers golden yellow.
distribution and habitat
The way has been only in a very small area in San Luis in the Peruvian province of La Convención northwest of Cusco detected at altitudes from 3272 to 3354 meters. She lives there on the ground in the rainforest.
Way of life and development
Little is known about the way of life of Bryophryne gymnotis . The animals live hidden under moss or rocks during the day. In the morning hours, vocalizations of the males were perceived. The call is a short, single note that is repeated at irregular intervals and is sent out with a dominant frequency of 3.01 kHz and a harmonic at 4.45 kHz. One egg clutch found consisted of 19 eggs, which were 4.0 to 4.8 millimeters in diameter. The brood goes through a direct development on land without completing a tadpole stage in the water. The transformation to the finished young frog thus takes place within the egg.
Danger
Since the species has only been found in a very small area northwest of Cusco so far, no meaningful results on frequency or endangerment are available. It is therefore initially classified by the World Conservation Organization IUCN as ( data deficient = insufficient data basis). The extent to which some road construction works and agricultural activities planned in this region will have a negative impact on their habitat still has to be investigated.
