Odorrana graminea

Large odorous frog, Odorrana graminea, is a species of frog in the family Ranidae. It is found in southern China (from southern Anhui and northern Zhejiang west to extreme southern Gansu, southeastern Sichuan, and southern Yunnan to the border of Vietnam, Laos and Myanmar, although it has not yet been recorded in the latter two countries. Its type locality is the Wuzhi Mountain in Hainan.[3] Until the revision of "Rana livida" in 2003,[4] this frog was considered a synonym of Odorrana livida.[3] The species occurs near fast-flowing rivers and streams in montane (sub-)tropical forests.[1]

Description

Odorrana graminea have a dorsoventrally compressed body with large eyes. Dorsum is green with smooth skin; flanks are brown with yellow marbling and with slight granulations. They are relatively large frogs, particularly the females: females grow to a snout–vent length of 78–100 mm (3.1–3.9 in), whereas males attain a more modest length of 42–53 mm (1.7–2.1 in). Apart from size, males differ from females by their relatively smaller digital disks, strong forearms, relatively larger tympanum, velvety nuptial pads on thumb, and paired gular pouches below jaw articulations.[4]

Odorrana graminea can produce ultrasonic calls. This is very rare among non-mammalian vertebrates, but has been shown for the related concave-eared torrent frog Odorrana tormota. However, it does not have recessed ears, a feature believed to be important for ultrasonic hearing in O. tormota. Exactly how O. graminea detects ultrasound remains to be determined.[5]
