We provide a taxonomic redescription of the Fawn Antechinus, Antechinus bellus (Thomas). A. bellus is the only member of its genus to occur in Australia's Northern Territory, where it can be found in savannah woodlands of the Top End. It is perhaps the most distinctive antechinus, and clearly distinguishable from the other 10 extant species of antechinus found in Australia: externally, A. bellus has pale body fur, white feet and large ears; A. bellus skulls have large auditory bullae and narrow interorbital width, while broadening abruptly at the molar row; mitochondrial and nuclear genes clearly distinguish A. bellus from all congeners, phylogenetically positioning the Fawn Antechinus as sister to Queensland's A. leo Van Dyck, 1980, with which it shares a curled supratragus of the external ear and a similar tropical latitudinal range.
我们对浅黄袋鼬（Antechinus bellus (Thomas)）进行了分类学重新描述。浅黄袋鼬是其属中唯一出现在澳大利亚北领地的成员，在该地顶端地区的热带稀树草原林地中可以发现它。它可能是最具特色的袋鼬，并且明显有别于在澳大利亚发现的其他10种现存袋鼬物种：在外部特征上，浅黄袋鼬身体皮毛浅色，足部白色，耳朵大；浅黄袋鼬的头骨有大的听泡和狭窄的眶间宽度，而在臼齿列处突然变宽；线粒体基因和核基因清楚地将浅黄袋鼬与所有同属物种区分开来，从系统发育角度将浅黄袋鼬定位为昆士兰州的利奥袋鼬（A. leo Van Dyck, 1980）的姐妹种，二者共享卷曲的外耳道上耳屏以及相似的热带纬度分布范围。
