    摘要:

    2024年5月和7月,于西藏亚东县和墨脱县采集到一批蝙蝠标本,包括2只明显无尾,形态特殊的个体。其中,GZHU24066号标本体小、无尾、具复杂鼻叶结构,前臂长为41.84 mm;耳大而圆,耳廓半透明;背腹毛各异,背毛毛尖黑褐色,腹毛毛尖偏白;头骨较小,枕孔位置低平,与颅面近似平行,符合无尾蹄蝠(Coelops frithii)形态特征。另一标本GZHU24298,体型较大,前臂长为53.96 mm;无尾、无鼻叶结构;眼大而明显,耳缘与耳廓同色,鼻孔略呈管状;背毛灰褐色,腹毛颜色较浅,呈褐色;头骨较大,眼眶大,鼻骨前端上翘,颧骨较薄,符合泰国无尾果蝠(Megaerops niphanae)形态特征。基于Cyt b基因1 140 bp序列所构建的系统发育树支持上述鉴定结果。本发现为无尾蹄蝠和泰国无尾果蝠在中国西藏分布的新记录。

    Abstract:

    To investigate the distribution of Chiroptera in the Xizang Autonomous Region of China, a series of field surveys were conducted in 2024. A Coelops bat (GZHU24066) was captured in May from Yadong County (27°20′49.55″ N, 88°59′17.05″ E, 2 413 m elevation) and a Megaerops bat (GZHU24298) was captured in July from Motuo County (29°12′36.86″ N, 95°6′29.16″ E, 739 m elevation). Morphological and cranial measurements were performed, including body weight, head and body length, forearm length, tibia length, ear length, hind-foot length, greatest skull length, condylo-basal length, condylo-canine length, palatal length, rostral height at C1, braincase breadth, braincase height, mastoid width, interorbital width, zygomatic width, anterior canine width, third molar width, maxillary toothrow, mandibular toothrow, mandibular length, and mandibular height. Genomic DNA was extracted using the Maibo DNA Extraction kit, and the cytochrome b (Cyt b) gene segment was amplified for sequence alignment and phylogenetic analysis. GZHU24066, identified as Coelops frithii, is small and tailless, with a complex nose-leaf structure and a forearm length of 41.84 mm (Table 1). It features large, rounded, translucent ears, dorsal fur with blackish-brown tips, and lighter ventral fur. The skull is small, with a low-positioned foramen magnum nearly parallel to the facial plane, aligning with C. frithii characteristics (Fig. 1). GZHU24298, identified as Megaerops niphanae, is larger, tailless, and lacks a nose-leaf, with a forearm length of 53.96 mm (Table 1). It has prominent eyes, ears with matching edge coloration, slightly tubular nostrils, grayish-brown dorsal fur, and lighter brown ventral fur. The skull is larger, with wide eye sockets, an upturned nasal bone, and a slender zygomatic arch, consistent with M. niphanae (Fig. 1). Phylogenetic analysis ofCyt b sequences corroborated these identifications (Fig. 2). These findings confirm the presence of Coelops frithii and Megaerops niphanae in Xizang, China, extending their known distributional ranges and enhancing knowledge of regional biodiversity.
