Both morphological and molecular data support its validity. The new species is characterized by： （1） presence of keratinized nuptial spines on the thenar region of the hands in males of the new species, in contrast to F. taihangnica and F. quadranus; （2） of females, the ratios of UEW, INS, NSD and IPTL to SVL ofF. kangxianensis were significantly less than those of F. taihangnica and F. quadranus （P 〈 0.05）, while the ratio of IOS to SVL of the new species was significantly larger than that of the latter two species （P 〈 0.05）; and （3） of males, the ratios of INS, NSD, IPTW to SVL of the new species were significantly less than those ofF. taihangnica and F. quadranus （P 〈 0.05）, while the ratio of HL to SVL of the former was significantly larger than that of the latter, and the ratio of HW to SVL ofF. kangxianensis was significantly larger than that of F. taihangnica but less than that of F. quadranus, the ratio of OPTL to SVL of F. kangxianensis was significantly less than that of F. taihangnica but larger than that of F. quadranus （P 〈 0.05）. The three species of Feirana can be easily identified and significantly differ from each other by the canonical discriminant analyses with high correct classification （〉92%）. Concurrently, based on partial mitochondrial ND2 gene sequences, the result of the molecular phylogenetic analyses of the Feirana indicates that the F. kangxianensis is sister to F. taihangnica.展开更多
