 Megophrys mangshanensis Fei et Ye, new species 



Holotype: No. 75 I 0689, adult female; collected in Mangshan, Yizhang County, 

 Hunan province at 1000m elevation on June 10, 1975. 



Allotype: No. 75 I 0907, adult male; collected in the same place as holotype on 

 June 25, 1975. 



Diagnostic characters: The main distinguishing differences of this new species 

 from its similar species M. lateralis (Anderson) are: no lateral fringes on toes and no 

 webbing between toes; a very distinct dark spot on mid-dorsal body, "X"-shaped, 

 connects anteriorly with triangular spot on head; nasals are far separated from each other; 

 nasals in contact with frontoparietal and sphenethmoid, from dorsal view, sphenethmoid 

 does not enter the orbit. In contrast, M lateralis has lateral fringes on toes; webbing basal; 

 dark spot on mid-dorsal body "Y"-shaped, not in contact with triangular spot on head; 

 nasals in contact with each other, but not in contact with frontoparietal or sphenethmoid, 

 from dorsal view, sphenethmoid enters the orbit. 



Morphological description: body length of holotype, adult female, is 73mm, 

 allotype male is 62.5mm; head flattened; snout tip shield-like, short and round, clearly 

 extends over mandible; canthus rostralis very distinct, loreal region vertical and concave; 

 tympanum clear; tongue pear-shaped; posterior end weakly notched; vomerine ridge very 

 distinct, its posterior end large, bearing 3—4 teeth. 



Finger tips ball-like, second finger shorter than first and fourth fmgers; no 

 subarticular tubercles, inner metacarpal tubercles weakly distinct. Hindlimb short, 

 tibio-tarsal articulation reaches eye; right and left heels overlap, tibia length over half of 

 body length, toe tips ball-like, third toe longer than fifth toe, no lateral fiinges on toes, no 

 webbing between toes (rudimentary web between metatarsals); no subarticular tubercles, 

 inner metacarpal tubercle flattened, slightly distinct, no outer metatarsal tubercle. 



Dorsal skin smooth, "V"-shaped narrow ridge formed by thin warts on posterior 

 part of head are not very distinct, either side of dorsal body bears a longitudinal skin ridge 

 formed by small warts, many small white spiny warts on posterior body; warts on both 

 sides of body smaller. A small horn on upper eyelid; upper lip margin bears saw tooth- 

 like papillae; supratympanic fold long, curving over tympanum to shoulder (it is more 

 straight and flattened in males compared to females), its hind part a little thicker, no bean- 

 like gland; white warts on temporal region. Dorsal body of hindlimb smooth, a few warts 

 appear on posterior thigh. A pair of axillary glands and femoral glands, about equal to 

 width of finger tip and toe tip. 



Secondary sex characters: first and second fingers of males bear brown nuptial pads, 

 internal single subgular vocal sac exists, opening of vocal sac long and interrupted.
