摘要: 鼩鼱类动物多样性丰富,但因体型小、外形相似使其物种鉴定比较难。本文利用数码互动显微系统,对鼩形目鼩鼱科6 个物种背部针毛的鳞片和髓质微观结构进行比较。结果表明,6 种鼩鼱鳞片结构类型分为花瓣型、椭圆型、斜长方型、长戟型、竹节型、草芽型、波浪型、平滑型、锯齿型9 种类型,具有种的特异性,能
够用来鉴定这6 个鼩鼱物种;而髓质结构类型多数表现为条纹型,不能单独用来鉴定物种。鼩鼱针毛的鳞片微观结构作为鼩鼱科动物的分类指标,具有可行性。

Abstract: Shrew diversity is rich in China. We often encounter difficulties in shrew species identification due to their small size and similar morphological characteristics. Here,scale and medulla patterns of dorsal guard hairs of six shrews in Soricidae were studied using microscopic digital interaction system. Scale patterns of dorsal guard hairs showed nine shapes,including petal shape,oblong shape,rhomboid shape,long hastate shape,bamboo-like shape, bud-like shape, wavy shape,smooth shape and serrated shape. The six shrews could be reliably identified through these scale patterns.However, most of the medulla patterns among the six shrews showed a striped shape and could not be used for the shrew species identification. Thus,it was feasible to use scale patterns of guard hairs as taxonomic characteristics to identify shrew species.
