Integrative revision of the montane Udea alpinalis group from the Palearctic Region (Insecta: Lepidoptera: Crambidae). Udea alpinalis group revision

DNA Barcode data for the montane Udea austriacalis and U. rhododendronalis indicate deep intraspecific splits, with specimens of both species grouping into several biogeographically separated groups. However, these allopatric splits are not reflected in the results of analyses of the two markers wingless and Elongation factor 1-alpha, except for U. austriacalis samples from the Pyrenees and the French Massif Central. Morphological investigation of the adults adds further evidence to the species status of these biogeographical groups. Accordingly, we remove the taxon Scopula donzelalis Guenée, 1854 from synonymy and reinstate the species as Udea donzelalis (Guenée, 1854) stat. rev., and delimit it from U. austriacalis Herrich-Schäffer, 1851 stat. rev. Furthermore, Udea altaica (Zerny, 1914) stat. n. from the Mongolian central Altai mountains, U. juldusalis (Zerny, 1914) stat. n. from the Tian Shan mountains of Kazakhstan, Kyrgyzstan and NW China, and U. plumbalis (Zerny, 1914) stat. n. from the Sayan Mountains of North Mongolia are raised to species level based on diagnostic morphological characters, and lectotypes of all three species are designated. We present evidence of introgression of U. alpinalis into U. uliginosalis at three localities in the Central Alps. A screening for Wolbachia using the markers wsp, gatB and ftsZ went negative for the studied specimens of the U. alpinalis species group.

针对山地类群奥地利螟蛾（Udea austriacalis）与杜鹃螟蛾（Udea rhododendronalis）的DNA条形码（DNA Barcode）数据显示其存在显著的种内深层分化，两个物种的标本均聚类为多个生物地理分隔的类群。然而，除采自比利牛斯山脉与法国中央高原的奥地利螟蛾样本外，基于无翅基因（wingless）与延伸因子1-α（Elongation factor 1-alpha）的两项标记分析结果并未反映出这些异域分化事件。对成虫的形态学研究为这些生物地理类群的物种地位提供了进一步佐证。据此，我们将分类单元*Scopula donzelalis* Guenée, 1854从同物异名中移除，并恢复其有效种地位为*Udea donzelalis* (Guenée, 1854) stat. rev.，同时将其与奥地利螟蛾*Udea austriacalis* Herrich-Schäffer, 1851 stat. rev.明确区分。此外，基于鉴别形态特征，我们将来自蒙古中部阿尔泰山的*Udea altaica* (Zerny, 1914) stat. n.、来自哈萨克斯坦、吉尔吉斯斯坦与中国西北天山山脉的*Udea juldusalis* (Zerny, 1914) stat. n.，以及来自蒙古北部萨彦岭的*Udea plumbalis* (Zerny, 1914) stat. n.提升为种级分类单元，并为这三个物种指定了选模标本。我们还在中阿尔卑斯山脉的三个采样点发现了高山螟蛾（Udea alpinalis）向沼生螟蛾（Udea uliginosalis）发生基因渐渗的证据。利用wsp、gatB与ftsZ标记对沃尔巴克氏体（Wolbachia）进行筛查的结果显示，供试的高山螟蛾类群标本均未检测到该共生菌。
