In May and June of 1977, based on the initial survey of the amphibians of Tibet 

 in 1973, the Northwest Institute of Biology, Academia Sinica, once again, went to 

 Yadong, Chuona, Motuo in the south part of Tibet for an important survey. We also 

 made short visits to Rikaze, Langxian, Linzi, Bomi, Mangkang, and other places. We 

 found two new species. Type specimens are kept separately in the Northwest Plateau 

 Institute of Biology, Academia Sinica, and the Chengdu Institute of Biology, Academia 

 Sinica 



New species: Megophrys pachyproctus Huang, sp. nov. 



Type species : Holotype Cf (No. 770650), Allotype 9 (No. 770652) and Paratype 

 1 (S (No. 770651), all collected on July 28, 1977 in Gelin, Motuo County, Tibet at an 

 elevation of 1530m by Huang Yongzhao. 



Diagnostic Characters : This new species is very similar to Megophrys minor 

 Stejneger. The main differences are: the new species bears a vomerine ridge, lower part is 

 swollen and bears thin teeth; the posterior end of the body of the male protrudes a slight 

 bit and has an arc-shaped swelling. However, M minor does not bear vomerine teeth, the 

 posterior body of male does not have an arc-shaped swelhng. Compared with M. 

 omeimontis, body shape of adult new species is distinctly smaller.
