A new tiger beetle species, Eunota albicauda Duran, Roman Huber n. sp., of the tribe Cicindelini, is described from the Gulf Coast of southern Texas. It is superficially most similar to E. togata (LaFert-Snectre, 1841) and E. circumpicta (LaFert-Snectre, 1841) but is distinguished on the basis of multiple character states not shared with either species. We reconstructed a phylogeny for Eunota to address the placement of this new taxon. Little is known about the biology or distribution of this exceedingly rare species. Despite extensive tiger beetle collecting from this region, only two specimens of E. albicauda n. sp. are known, collected in the mid-20th century. Future efforts to locate additional specimens should focus on coastal salt flats and marshes in southern Texas, including areas near the United States-Mexico border, late in the season (September-October).
一种新的虎甲物种，Eunota albicauda Duran，Roman Huber n. sp.，属于 Cicindelini 部落，来自德克萨斯州南部的墨西哥湾沿岸。它在外观上与 E. togata (LaFert-Snectre, 1841) 和 E. circumpicta (LaFert-Snectre, 1841) 最为相似，但由于与这两个物种都没有共享的多个特征状态而被区分开来。我们为 Eunota 重建了一个系统发育树，以解决这个新分类群的位置问题。关于这个极其罕见的物种的生物学或分布知之甚少。尽管在该地区进行了广泛的虎甲虫收集，但仅发现了两种新种 E. albicauda n. sp. 的标本，它们是在 20 世纪中期采集的。未来寻找更多标本的努力应集中在德克萨斯州南部的沿海盐滩和沼泽地，包括靠近美墨边境的地区，在季节后期（9 月至 10 月）。
