Morphological data revealed that the new species, Occidozyga shiwandashanensis sp. nov., differs from its congeners by a combination of the following characters: (1) medium body size (SVL 25.2-33.8 mm in males, 34.9-38.9 mm in females); (2) pale brown dorsum with irregular pale dark spots, especially on head; (3) creamy white ventral surface with brown spots on lateral margin and throat; (4) tongue fleshy, rounded, without notch, (5) tympanum hidden; (6) finger webbing absent and toe webbing full, but fourth toe not webbed to discs; (7) tips of fingers pointed, tips of toes rounded, slightly expanded into disc. (2021) and were taken with a digital caliper to the nearest 0.1 mm. Measurements included: snout-vent length (SVL); head length from tip of snout to rear of jaws (HL); head width at commissure of jaws (HW); distance from eye front to nostril (EN); snout length from tip of snout to anterior eye corner (SNT); diameter of exposed portion of eyeball (ED); nostril-eyelid length (N-EL); internarial space distance (IN); interorbital distance (IOD); upper eyelid width (UEW); forelimb length from elbow to tip of finger III (FLL); hand length (HAL); tibia length with flexed hindlimb (TIB); foot length from tibiofibular end to tip of fourth toe (FL); thigh length from vent to knee (THL); first toe length (1TOEL); and inner metatarsal tubercle length (IMTL). [...]we described the specimens as a new species.
