with grayish white narrow stripe; pelvis, both anterior and posterior femur and anterior 

 part of ventral femur are all orange-red colored; finger and toe tips hght red; tarsal, 

 metatarsal and ventral toes grayish brown or black-brown; many grayish black spots 

 scattered on lateral body and whole ventral body, a grayish black short longitudinal stripe 

 in the middle of throat region is distinct; small milky white spots along lower lip edge. 

 Color marking on dorsal and ventral body in female are lighter than in male. 



Secondary sex characters: first finger of male bears gray nuptial pad, with dense 

 nuptial spines on it; internal single subgular vocal sac exists, opening of vocal sac small 

 and interrupted; posterior body has swelling which protrudes a little bit and arc-like; no 

 linea musculinae. 



Ecology : On a rainy night of July 28, 1977, in the forest about 1500m above sea 



level, following the call that was a continuous "gazhi — gazhi — gazhi — ", two male 



Megophrys were collected in the bushes and branches of shrubs; a female was collected 

 beside road which was not far away from a flowing ditch. 



New species Rana conaensis Fei et Huang, sp. nov. 



Rana liebigii Herpetology Research Section, Sichuan Institute of Biology, 1977, 

 Acta Zoological Sinica, 23(l):56-57. (specimen from Chuona) 



Type specimen : Holotype Cf (No. 770531, collected on June 30, 1977 in Mama, 

 Chuona County, Tibet at the elevation 2900m, by Huang Yongzhao), allotype 9 (No. 

 770532, collected at the same time and same place with holotype), paratype (22d'C?, 8 

 99, 26 juveniles, ova and tadpoles, collected on June 24-30, 1977 in Mama, Chuona 

 County, Tibet, at the elevation of 2900-3400m, Northwest Institute of Biology. 2 <S<S, 1 

 9, 3 juveniles and tadpoles, collected on August 7 in Mama, Chuona County, Tibet at the 

 elevation of 2900m,Chengdu Institute of Biology') 



Diagnostic Characters : The new species is smiliar to Rana liebigii Guenther. 

 Body size of new species is small, the largest body length of adult frog is not greater than 

 70mm, no dorsolateral fold; skin on both sides of anal region forms a slight "A"-shaped 

 air-filled sac, very distinct; intemal arm of male frog does not bear cone-shaped black 

 spines. Body size of Rana liebigii large, the greatest body length of an adult frog is more 

 than 100mm; dorsolateral fold exists; skin on anal region does not bear air-filled sac; inner 

 arm of male bears cone-shaped black spines. 



Descrption of morphology : Average body length is 58mm in males, 55mm in 

 females; head width slightly larger than head length, snout tip blimtly rounded, protruding 



' * In 1977, two CfC?, one 9, three juveniles collected by Mr. Wenxuan Chao of Fishery 

 Institute of Biology, Academia Sinica in Mama, Chuona County on August 7, 1974, were 

 regarded as Rana liebigii. Now after obtaining more of the same species, we think they should 

 be this new species, Rana conaensis.
