The Australian Orchesellidae includes only 11 nominal species in four genera: Australotomurus Stach, 1947, Alloscopus Brner, 1906, Heteromurus Wankel, 1860, and Falcomurus Mandal, 2018. Here we describe Dicranocentrus dolosus sp. nov. from Cocos and Keeling Islands, the first species of the genus to be recorded from Australia. The new species is similar to D.inermodentes (Uchida, 1944) and D.indicus Bonet, 1930, but differs from both by the combination of the ventral head, mesothoracic and dental chaetotaxy. We also revisit Australotomurus based on previous studies to better interpret the dorsal macrochaetotaxy of the genus, and provide a synthetic map of chaetae to guide future studies on scaleless Orchesellidae. Finally, we present updated diagnoses to all genera and species of Australian Orchesellidae, as well as an identification key to all species.
澳大利亚Orchesellidae 科仅包括四个属中的 11 个学名种：Australotomurus Stach, 1947、Alloscopus Brner, 1906、Heteromurus Wankel, 1860 和 Falcomurus Mandal, 2018。本文描述了来自科科斯（基林）群岛的 Dicranocentrus dolosus sp. nov.，这是该属在澳大利亚的首次记录。新种与 D.inermodentes (Uchida, 1944) 和 D.indicus Bonet, 1930 相似，但与这两个种的区别在于头腹面、中胸和齿状毛的组合。我们还根据先前的研究重新审视了 Australotomurus，以更好地解释该属的背面宏观毛序，并提供了一个毛序综合图，以指导未来无鳞 Orchesellidae 的研究。最后，我们提供了澳大利亚 Orchesellidae 所有属和种的更新诊断，并提供了所有种的鉴别特征。
