    Abstract:

    The hyobranchial apparatus features of adult and subadult Hynobius guabangshanensis were observed by clearing and double-staining method. In adult,the middle of hypohyal was crossed; the end of ceratohyal was covered by a complex of hyobranchial Ⅰ and ceratobranchial Ⅰ; basibranchial plate was present; ceratobranchial Ⅱ was ossified; urohyal was also ossified and showed a"一"shape. In subadult,the middle of hypohyal was not crossed; hyobranchial Ⅰand ceratobranchial Ⅰwere present separately; basibranchial plate was not presented,ceratobranchial Ⅱ was not ossified; ceratobranchial Ⅲ and ceratobranchial Ⅳ were present,and both were cartilage; urohyal was not ossified and showed a "1 " shape. These changes of morphological characters may be caused by the function of hynobranchial apparatus in adult and subadult.
