Rhinolophus yunanensis Dobson, 1872 Rhinolophidae Burgin, Connor 6WTQV Dobson 1872 [2778,3410,1562,1623] Mammalia Rhinolophidae Rhinolophus Animalia Chiroptera 52 331 Chordata species yunanensis   106. Dobson’s Horseshoe Bat  French: Rhinolophe duYunnan/  German: Dobson-Hufeisennase/ Spanish: Herradura de Yunnan  Taxonomy.  Rhinolophus yunanensisDobson, 1872,  “  Hotha, Yunan,” China.    Rhinolophus yunanensisis included in the  pearsoniispecies group. Populations now attributed to  thailandensiswere previously considered to represent R yunanensis,incorporating specimens from Thailand. The study that described  R. thai- landensisonly examined specimens of  R. yunanensisfrom Yunnanand Sichuan, China, and Thailand; this leaves some ambiguity regarding the rest of the distribution attributed to  R.yunanensis.The paper restricted  R.yunanensisto China, but the rest of the distribution is here included tentatively under this species, until a revisionincorporating specimens from the whole range is undertaken. Monotypic.    Distribution.Known with certainty only from S China( Sichuanand Yunnan), butpopulations from NE India( Arunachal Pradeshand Mizoram) and N & E Myanmarare tentatively included in this species; a dubious record in Guizhou(S China) and itmay occurin Laos.  Descriptive notes.Head—body 52- 4—72 mm, tail 18-28 mm, ear 19- 9—27 mm, hindfoot 10-8-14- 7 mm, forearm 55-5—59- 2 mm; weight 20-22 g. Fur is woolly, glossy, and dense; dorsal pelage is light grayish brown to dark gray (hairs unicolored), while ventral pelage is paler. Ears are medium-sized to large. Noseleaf has a long, triangular, straight-sided lancet; connecting process forms a low, rounded arch; sella has a wide base that narrows toward the middle and tapers slightly toward the tip; horseshoe is wide (12- 5—14 mm), covering the whole muzzle, and has a deep and distinct median emargination. Lower lip has one mental groove. Baculum is relativelyshort but strong ( 4 mmlong) and has a strong basal cone (strong compared to the ThailandHorseshoe Bat,.  thailandensis)and a roughlycylindrical shaft; tip is narrowly rounded offand laterallywidened. Skull is large and heavily built (zygomatic width much greater than mastoid width); anterior median swellings are longer than wide(width is less than in the ThailandHorseshoe Bat); lateral swellings are much larger than the anterior ones; sagittal crest is strong, especially anteriorly; frontal depression is relativelyshallow; supraorbital crests are low but well defined. C1 is strong and well developed; P2 is large and in the tooth row; P3 is moderate in size and more or less extruded from the tooth row, or very rarelyabsent. Dental formula is the typical of 32 teeth or 30 when a lower premolar is missing. Chromosomal complement has 2n = 46 and FNa = 60 (Sichuan) or 2n = 44 and FNa = 60 (Guizhou, possibly refers to Pearson’s Horseshoe Bat,  R.pearsonii).  Habitat. Commonly found in dense hilly forests among bamboo clumps, and is often recorded around limestone caves. Dobson’s Horseshoe Bat is known from bamboo thickets in China, where it may roost. Typically found at elevations of 600-1300 m.  Food andFeeding. No information. Breeding. No information.  Activity patterns.Dobson’s Horseshoe Bat roosts in limestone caves and has been captured in bamboo thickets and thatched roofs. An echolocation call from Sichuanwith a peak F of 48 kHz probably represents this species.  Movements, Home range and Socialorganization. No information.   Status and Conservation.Classified as Least Concern on The IUCNed List.Dobson’s Horseshoe Bat appears to be uncommon throughout much of its distribution. It greatest threat is probably local habitat loss due to commercial logging and agricultural expansion; there do not appear to be any majorthreats identified at the moment.   Bibliography.Bates & Harrison (1997), Bates, Bumrungsri, Csorba, Molur & Srinivasulu (2008b), Bates, Thi Mar-Maret al.(2004), Csorba et al.(2003), Francis (2008a), Gu Xiaoming (2006), Hill(1986 b), Molur etal.
