Abstract

Abstract - Etheostoma punctulatum (Stippled Darter) was recently redescribed to recognize 2 additional species, E. autumnale (Autumn Darter) and E. mihileze (Sunburst Darter), as part of the E. punctulatum species complex. This taxonomic update rendered the collection of Stippled Darters in the Arkansas Tech Fish Collection (ATFC) inaccurate since the stored specimens were collected well before and just after the redescriptions. Upon reassessment, we found that the ATFC did not contain any specimens now considered as Stippled Darters but, instead, contained specimens of the 2 newly described species and misidentified Nothonotus juliae (Yoke Darter). We concluded that the collection consisted of 54 Autumn Darters, 96 Sunburst Darters, and 220 Yoke Darters. Additionally, external quantitative and qualitative characteristics did not exactly follow the expected trends as laid out in the study that described the new species. This study serves as a small, but clear, example of the importance of curating and updating natural history collections like that of the ATFC, for they play a vital role in a number of different areas of study including biogeographic range changes, phenological shifts, evolutionary changes, and more.

适应短吻鳄（Etheostomatinae）分类的变化：重新评估自然历史收藏品中保存的标本

摘要--Etheostoma punctulatum（条纹箭鱼）最近被重新描述，将另外 2 个物种 E. autumnale（秋箭鱼）和 E. mihileze（旭日箭鱼）认定为 E. punctulatum 种群的一部分。由于阿肯色技术鱼类保藏中心（ATFC）所保藏的条纹镖鱼标本是在重新描述之前和之后采集的，因此这次分类学更新使得阿肯色技术鱼类保藏中心（ATFC）所保藏的条纹镖鱼标本不准确。经过重新评估，我们发现 ATFC 中并不包含任何现在被认为是条纹镖鱼的标本，而是包含了 2 个新描述的物种和被误认为是 Nothonotus juliae（Yoke Darter）的标本。我们的结论是，采集到的标本包括 54 条秋短吻鳄、96 条旭日短吻鳄和 220 条轭短吻鳄。此外，外部的定量和定性特征并不完全符合描述该新物种的研究中提出的预期趋势。这项研究是一个很小但很明显的例子，说明了整理和更新像 ATFC 这样的自然历史藏品的重要性，因为它们在生物地理范围变化、物候变化、进化变化等多个不同的研究领域发挥着至关重要的作用。

期刊介绍： The Southeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the southeastern portion of North America, roughly bounded from North Carolina south to Florida, west to Texas, north to Oklahoma, and east back to North Carolina. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion.
