The Epicopeiidae is a small geometroid family distributed in the East Palaearctic and Oriental regions. It exhibits high morphological diversity in body size and wing shape, while their wing patterns involve in various complex mimicry rings. In the present study, we attempted to describe a new genus, and a new species from Vietnam, with comments on two assumed congeneric novel species from China and India. To address its phylogenetic affinity, we reconstructed the phylogeny of the family by using sequence data of COI, EF-1α, and 28S gene regions obtained from seven genera of Epicopeiidae with Pseudobiston pinratanai as the outgroup. We also compared the morphology of the new taxon to other epicopeiid genera to affirm its taxonomic status. The results suggest that the undescribed taxon deserve a new genus, namely Mimaporia gen. n. The species from Vietnam, Mimaporia hmong sp. n., is described as new to science. Under different tree building strategies, the new genus is the sister group of either Chatamla Moore, 1881 or Parabraxas Leech, 1897. The morphological evidence, which was not included in phylogenetic analyses, however, suggests its potential affinity with Burmeia Minet, 2003. This study also provides the first, although preliminary, molecular phylogeny of the family on which the revised systematics and interpretation of character evolution can be based.
钩蛾科是一个小型尺蛾总科的家族，分布于东洋界和古北界东部地区。它在体型和翅形上表现出高度的形态多样性，而其翅纹涉及各种复杂的拟态环。在本研究中，我们试图描述一个来自越南的新属和新物种，并对来自中国和印度的两个假定同属新物种进行评论。为了解决其系统发育亲缘关系，我们以伪钩蛾（Pseudobiston pinratanai）为外类群，利用从钩蛾科七个属获得的细胞色素氧化酶亚基I（COI）、延伸因子1α（EF-1α）和28S基因区域的序列数据重建了该科的系统发育。我们还将新分类单元的形态与其他钩蛾科属进行了比较，以确认其分类地位。结果表明，这个未描述的分类单元应归属一个新属，即拟钩蛾属（Mimaporia gen. n.）。来自越南的物种，即越南拟钩蛾（Mimaporia hmong sp. n.），被描述为科学新物种。在不同的建树策略下，新属是1881年的查塔姆拉钩蛾属（Chatamla Moore）或1897年的副钩蛾属（Parabraxas Leech）的姐妹群。然而，未纳入系统发育分析的形态学证据表明，它可能与2003年的缅甸钩蛾属（Burmeia Minet）有亲缘关系。本研究还提供了该科首个（尽管是初步的）分子系统发育，可为修订的系统分类和性状进化解释提供依据。
