A NEW SPECIES OF TREE MICE FROM YUNNAN,CHINA

This paper deals with a new species cf the gents Chiropocomys Peters collected from Yunnan in 1981. The type specimens are deposited in the Ecological Department of Kunming Branch, Academia Sinice, Kurming,Chiropodomys jingdongensis, sp. nov. Holotype. No. 81369, an adult male collected on June 14, 1981, uy authors from Jingdong (alt. 2430m.), Yunnan.Faratypes:Ncs. 81360, 81424, 81433, three adult females collected from the same locality in June, 1981.Specimens examined; A sutadult male and an adult female collected from the same locality.Diagnosis. The new species is similar to C. gliroides, but differs in having larger skull and bulla; at least there are plenty of lateral stiff hairs on the terminal half of tail and they are so long that make the tail feather-like.Remark. The classification of this genus wasn't clear; until the monograph of this genus was published by Musser in 1979. According to Musser who examined 379 specimens obtained from a lot of localities of Indochina and the Malay Archipelage, this genus has contained 5 species occurring from Assam, Burma, Siam, Laos, South China, Annam, to Sumatra, Java, Borneo and Philippines. In the course of making comparison, the following results may be found.First, all known forms living on the islands differ from the new species in size and color. C. karlkoopmani, C. major and C. calamianensis are significantly larger than the new species, nevertheless C. muroides is smaller. The underparts of C. karlkoopmani and C. muroides have pale gray and buffy dark gray, respectively, but that of the new species is white; the tail of the former, basal 1/3 is brown and the rest white, but that of the new species is brown. In addition the upperparts of C. calamionensis is rather bright, bright buffy brown or chestms, end that of the new species is grayish buff-brown.Next, the new species is similar to C. gliroides occurring on the mainland uniquely in size, but the average length of the skull and the bulla is larger. Also, the stiff hairs on the terminal half of the tail for new species are mere plentiful and longer than trat cf the latter just as it's shewn in the figure.So far as we have studied, it can be concluded that the tree mice collected in Jingdong, Yunnan must be a new species,
