Abstract

Ourapteryx is widely distributed in the Palearctic and Oriental regions, with the highest species diversity found in China. As of 2024, 95 described species have been recorded globally; however, no comprehensive revision of this genus has been published. Identifying Ourapteryx species based solely on wing patterns is challenging due to their extreme similarity, often leading to frequent misidentifications and the oversight of cryptic species. In this study, we utilized 68 morphological species, along with 1050 COI sequences, to develop an integrative taxonomy for Ourapteryx. This taxonomy integrates morphological, molecular, distributional, and ecological evidences. Our findings identified nine candidate species (labeled as sp1–sp7, O. horishana and O. brachycerca), increasing the total number of recognized species from 68 to 77. Using this updated checklist, we compared four molecular delimitation methods against the outcomes of morphological taxonomy. The analysis indicated that a 2% threshold produced the highest efficiency. Additionally, we explored the reasons behind morpho-molecular discordance and the presence of hidden species. Our study underscores the importance and reliability of integrative taxonomy, which relies on multiple lines of evidence for accurate species identification and classification.

基于分子和形态学证据的疏翅Ourapteryx Leach的综合分类(尺蛾科,鳞翅目
Ourapteryx广泛分布于古北和东方地区,是中国物种多样性最高的地区。截至2024年,全球已记录的物种有95种;然而,该属的全面修订尚未发表。仅仅根据翅膀图案来识别Ourapteryx物种是具有挑战性的,因为它们非常相似,经常导致频繁的错误识别和对神秘物种的疏忽。在这项研究中,我们利用68个形态学物种,以及1050个COI序列,建立了Ourapteryx的综合分类。该分类综合了形态学、分子学、分布学和生态学的证据。本研究共鉴定出9个候选种(标记为sp1-sp7、O. horishana和O. brachycerca),使鉴定种总数从68个增加到77个。利用更新后的清单,我们将四种分子划界方法与形态学分类结果进行了比较。分析表明,2%的阈值产生最高的效率。此外,我们还探讨了形态分子不一致和隐藏物种存在的原因。我们的研究强调了综合分类学的重要性和可靠性,它依赖于多种证据来准确地识别和分类物种。

期刊介绍: The Journal of Zoological Systematics and Evolutionary Research (JZSER)is a peer-reviewed, international forum for publication of high-quality research on systematic zoology and evolutionary biology. The aim of the journal is to provoke a synthesis of results from morphology, physiology, animal geography, ecology, ethology, evolutionary genetics, population genetics, developmental biology and molecular biology. Besides empirical papers, theoretical contributions and review articles are welcome. Integrative and interdisciplinary contributions are particularly preferred. Purely taxonomic and predominantly cytogenetic manuscripts will not be accepted except in rare cases, and then only at the Editor-in-Chief''s discretion. The same is true for phylogenetic studies based solely on mitochondrial marker sequences without any additional methodological approach. To encourage scientific exchange and discussions, authors are invited to send critical comments on previously published articles. Only papers in English language are accepted.
