Remarks
Remark This species has only 14 presacral vertebrae, making it one of the shortest-bodied urodels known worldwide. Wang and Evans (2006b) considered P. sinensis a metamorphosed urodelan. This book considers the two pairs of ossified ceratobranchials and longitudinal vomerine tooth row to both be typical paedomorphic features. Therefore P. sinensis should be a paedomorphic urodelan.
