本文报道了印度尼西亚苏拉威西岛一新种，记录了其遗传特征和形态特征。这种新物种在岛上分布广泛，在岛上5个特有地区的9个一般地点有证实的记录。从形态上看，这一新物种很容易与其他已描述的苏拉威西鳄蜥区分开来，因为它的体型中等，皮毛灰色，尾巴长而多毛。新物种主要是在地下的陷阱中捕获的，但我们也获得了证据，表明它很容易爬树，并且在运动习惯上可能是掠食的。从整个岛屿取样的新物种种群是密切相关的，未经校正的线粒体p距离< 0.02。这个新物种是苏拉威西岛特有的鼩鼱种群的一员，目前已知有6个有效物种和几个未被描述的物种，都属于Crocidura属。这种辐射的物种限制和系统发育关系的解决受到模式地点栖息地丧失，使用非常小的样本量的新物种的历史指定以及缺乏模式标本的遗传数据的阻碍。
We describe a new species of Crocidura (Soricidae) from Sulawesi Island, Indonesia, documenting its novelty with both genetic and morphological characters. The new species is widespread on the island, with vouchered records from nine general localities distributed among five of the island’s areas of endemism. Morphologically, the new species is readily distinguished from all other described Sulawesi Crocidura by its intermediate body size, gray pelage, and long, hairy tail. The new species was mainly captured in pitfalls placed in the ground, but we also obtained evidence that it readily climbs trees and may be scansorial in its locomotor habits. Populations of the new species sampled from across the island are closely related, separated by< 0.02 uncorrected mitochondrial p-distances. The new species is one member of an endemic radiation of shrews on Sulawesi now known to contain six valid species and several undescribed species, all within the genus Crocidura. Resolution of species limits and phylogenetic relationships in this radiation is hindered by habitat loss at type localities, historical designation of new species using very small sample sizes, and a lack of genetic data from type specimens.
