We assign the only Australian leptestherid clam shrimp, Eoleptestheria ticinensis (Balsamo-Crivelli, 1859) to a new species status, Leptestheria timmsi sp. nov., based on the latest molecular phylogeny of spinicaudatan clam shrimps from a previous study. We provide a redescription of the species, highlighting morphological details not explored previously for this species. We also present a comparative account of all Eoleptestheria species and populations throughout the world. The head morphology of Leptestheria timmsi sp. nov. overlaps with other populations of Eoleptestheria and a few Leptestheria species. The telsonic and cercopod marginal spines seem to increase in size posteriorly in L. timmsi sp. nov., unlike in many other Eoleptestheria populations.
基于先前一项研究中对叶足介目蚌虾的最新分子系统发育分析，我们将仅分布于澳大利亚的叶足介目蚌虾，蒂奇内斯叶足介（Eoleptestheria ticinensis (Balsamo-Crivelli, 1859)）重新分类为一个新物种，即蒂姆西叶足介（Leptestheria timmsi sp. nov.）。我们对该物种进行了重新描述，突出了此前未探究过的形态学细节。我们还对全球所有的蒂奇内斯叶足介物种和种群进行了比较说明。蒂姆西叶足介的头部形态与蒂奇内斯叶足介的其他种群以及一些叶足介物种存在重叠。与许多其他蒂奇内斯叶足介种群不同，蒂姆西叶足介的尾节和尾足边缘刺似乎在后端会增大。
