We describe Odorrana liboensis sp.nov.,a new species from the Maolan National Nature Reserve,Libo County,Guizhou Province,China.Phylogenetic analyses based on DNA sequences of the mitochondrial 12S rRNA,16S rRNA,and ND2 genes supported the new species as an independent lineage,closely related to O.lipuensis.The uncorrected genetic distances between the 12S rRNA and 16S rRNA in the new species and its closest congener,O.lipuensis,were 6.06％ and 5.19％,respectively.The new species is distinguished from its congeners by a combination of the following morphological characters:(1) having medium body size,with the snout-vent length (SVL) of adult females approximately 1.2 times as long as males at 56.9 ±1.0 (55.8-58.2 mm,n =9) in females and 48.7 ± 12 (47.1-49.9 mm,n =5) in males;(2) head length greater than width in males and females;(3) tympanum distinctly visible,greater than one-half the diameter of the eye;(4) eyes big and prominent,width of upper eyelid (UEW) approximately 3/4 of eye diameter (ED);(5) dorsolateral folds absent;(6)two metacarpal tubercles;(7) relative finger lengths:Ⅱ ＜ Ⅰ ＜Ⅳ ＜ Ⅲ;(8) subarticular tubercles on fingers prominent:1,1,2,2;(9) one metatarsal tubercle;(10) tibiotarsal articulation reaching to between the eye and nostril when the leg is stretched forward;(11) toes with entire webbing to disks;(12) subarticular tubercles on toes prominent:1,1,2,3,2;(13)dorsal surfaces of limbs with distinct brownish-black bands;(14) smooth,grass-green dorsum with irregular brown mottling;(15) venter smooth,lacking black spots;and (16)lacking pectoral spinules,lacking vocal sacs,and light white nuptial pad present on finger Ⅰ in males.The new species is currently only known from the type locality.
