Rhacophorus translineatus is a frog from the family of row frogs (Rhacophoridae). It occurs in the Tibet Autonomous Region and in the Indian state of Arunachal Pradesh .

features

The head-torso length is 49 to 57 mm in the males. The females are slightly larger. The back is reddish brown. The belly is brownish yellow. The sides of the body have round oval spots. The triangular head is slightly longer than it is wide. Nine to twelve chocolate-brown transverse bandages run from the snout to the cloacal opening. The front and rear limbs are conspicuously banded in black. The pointed end of the snout shows a small, conical skin attachment that protrudes far beyond the lower jaw. The canthus rostralis is protruding. The side nostrils are at the same distance from the eyes and the tip of the snout. The Loreal area is oblique and concave. The eardrum and the supratympanic fold, a bulge in the skin that begins above the eardrum (tympanum) and often continues above the eyes, are noticeable. The tympanic diameter is half to two thirds of the diameter of the eye. The vomer teeth are arranged in oblique rows. The medium-length tongue is diamond-shaped and bilobed. At the base of the tongue there is a tooth-like protrusion on the lower jaw. The front limbs have a number of tiny glandular spots in the elbow area. At the cloaca there are four pairs of conspicuous glandular cusps above and two pairs below. The thighs have round, cream-colored spots. The flat, wide fingers are almost completely webbed. The fingertips have large adhesive discs. Their diameter is 1.5 to 2 times the tympanic diameter. The hind limbs are long and slender. The tibiotarsal articulation extends between the eye and the nostril. The toes are completely webbed. The webbed feet have conspicuous black markings. The calcar (a spur on the ankle joint) is claw-shaped. The inner heel hump is present, the outer one absent. Sexually mature males have milky white oestrus calluses on the first and second fingers, a throaty , internal vocal sac and a pink band of fibrous connective tissue along the midline of the back, the so-called linea masculinea. The skin on the back is smooth, the skin on the abdomen is granular. The tadpoles are blank.

distribution

The species is known from Lake Xigong in Mêdog County in the Tibet Autonomous Region and from the north of West Siang District in the Indian state of Arunachal Pradesh .

Habitat and way of life

Rhacophorous translineatus lives in subtropical primary forests at altitudes of 1,500 meters. It climbs small trees and can also be found on the leaves of banana trees. Its breeding grounds are on the banks of the lake. In case of danger, the frogs drop into the water.

status

The IUCN lists Rhacophorous translineatus in the category “insufficient data” ( data deficient ) because there are uncertainties regarding the distribution area, the status and the ecological requirements.
