Piebald odorous frog
© 2015 Sandra Goutte (1 of 5)
Description: O. schmackeri has a snout-vent length of approximately 42 mm. It is characterized by the presence of vomerine teeth, an oblique loreal region that is somewhat concave, the nostril being closer to the snout than the eye, a narrow interorbital region, and a distinct tympanum. The canthus rostralis is obtuse. The first finger is longer than the second and the fingers have expanded discs. The toes are webbed and the species has an indistinct inner metatarsal tubercle, but no outer tubercle. The skin is smooth or slightly corrugated (Boulenger 1920).
Coloration: It has a bluish green-grey dorsum, with black marbling. Its head and back also have brown or black spots. The sides have sharply defined round black spots and the limbs have dark cross-bars. The glandular fold below the tympanum is greenish white. The ventral sides are dirty white and the limbs are orange (Boulenger 1920).
Variation: Males have vocal sacs and spines all over the throat, thorax and belly. The body length in males is in the range of 37-46 mm (Liu 1950).
Distribution and Habitat
Life History, Abundance, Activity, and Special Behaviors
Odorrana schmackeri is capable of hearing much lower auditory frequencies than are heard by sympatric torrent species O. livida and Amolops tormotus. It does not respond to higher frequencies than 8.5 kHz, suggesting that the three species have unique responses to selection pressures (Yu et al. 2006).

Phylogenetic Relationships: The genus Odorrana and Eburana were initially both subgenera of Asian cascade frogs, within the genus Rana. After the first investigation of phylogenetics, Eburana was placed within Odorrana. In the light of phylogenetics, subgeneric reassessment of Southeast Asian Rana has been suggested (Matsui et al. 2005). Relationships within Odorrana have been found to coincide well with distribution patterns, indicating the Guizhou Plateau as the center from which the group radiated (Ye and Fei 2005)
