We here propose a new monotypic butterfly genus Nakahara & Espeland, to accommodate a new species, Lamas & Nakahara, , described and named herein. is a relatively common and widespread butterfly species which is recovered as a member of the so-called " clade" in the nymphalid subtribe Euptychiina, based on our molecular phylogenetic analysis using a maximum likelihood approach. Nevertheless, its sister group is not confidently resolved in any analysis, supporting a relatively distant relationship to any described genus as well as our decision to establish a new monotypic genus. We further discuss the proposed taxonomy in the light of frequent criticism of the description of monotypic taxa, as well as emphasize the importance of incorporating multiple evidence when describing new genera, illustrated by reference to several recent generic descriptions in this subtribe.
我们在此提出一个新的单型蝴蝶属——中原氏蝶属（Nakahara & Espeland），以容纳一个新物种——拉马斯氏蝶（Lamas & Nakahara），该物种在此处被描述并命名。基于我们使用最大似然法进行的分子系统发育分析，拉马斯氏蝶是一种相对常见且分布广泛的蝴蝶物种，它被归为蛱蝶科（Nymphalidae）尤普蒂奇亚族（Euptychiina）中所谓“进化枝”的一员。然而，在任何分析中，其姐妹群都未得到确切解析，这支持了它与任何已描述属的关系相对较远，以及我们建立一个新单型属的决定。我们根据对单型分类群描述的频繁批评，进一步讨论了所提议的分类法，并强调在描述新属时纳入多种证据的重要性，这一点通过参考该亚族最近的几个属的描述得以说明。
