A new spinicaudatan species, Eulimnadia pampa sp. nov., is described from Argentina mostly based on the differential egg morphology. This species was collected from rainwater pools from Buenos Aires City and the provinces of Buenos Aires and Entre Ríos, and compared to other Neotropical species. Previous Argentine record of E. brasiliensis is shown to belong to our new species, which represents the southernmost Neotropical Eulimnadia. We also present new records of the Paraguayan Eulimnadia ovisimilis Martin and Belk, 1989 from northeastern Argentina. Eulimnadia santiaguensis is treated as a species inquirenda, thus we recognize only three Eulimnadia species in Argentina: E. pampa sp. nov., E. ovilunata and E. ovisimilis, and we provide a brief indentification key. We present the first description and SEM images of the putative Eulimnadia spermatophore, which we found in the new species.
一种新的叶足鲎虫物种，即潘帕叶足鲎虫新种（Eulimnadia pampa sp. nov.），主要基于不同的卵形态从阿根廷被描述出来。该物种采集自布宜诺斯艾利斯市以及布宜诺斯艾利斯省和恩特雷里奥斯省的雨水池，并与其他新热带区物种进行了比较。之前阿根廷记录的巴西叶足鲎虫（E. brasiliensis）被证明属于我们的新物种，该新物种代表了新热带区最南端的叶足鲎虫。我们还给出了巴拉圭叶足鲎虫（Eulimnadia ovisimilis Martin and Belk，1989）在阿根廷东北部的新记录。圣地亚哥叶足鲎虫（Eulimnadia santiaguensis）被视为一个有待进一步研究的物种，因此我们在阿根廷仅认可三种叶足鲎虫物种：潘帕叶足鲎虫新种、卵形叶足鲎虫（E. ovilunata）和似卵叶足鲎虫（E. ovisimilis），并提供了一个简要的鉴定检索表。我们展示了在新物种中发现的疑似叶足鲎虫精荚的首次描述和扫描电子显微镜图像。
