以DNA條碼技術重新評估澳洲產星尺蛾之多樣性且避免破壞模式標本

Revision of the Australian Oenochroma vinaria Guenée, 1858 species-complex (Lepidoptera: Geometridae, Oenochrominae): DNA barcoding reveals cryptic diversity and assesses status of type specimen without dissection.

最近研究者利用全球鱗翅目生命條碼計畫(All Leps)的資料庫發現產於澳洲的尺蛾Oenochroma vinaria Guenée, 1858其實包含了兩個種。透過分析近年採集的標本以及150年前採集的的雌性選模標本的生命條碼片段,作者確認上述兩種之一是vinaria,另將Monoctenia decora處理為O. vinaria的同物異名,並指定了一隻選模標本。另一種是新種,作者將之命名為Oenochroma barcodificata sp. nov.,文中並有詳細的生活史描述,目前所知分布於塔斯馬尼亞以及新南威爾斯。

Abstract
The assembly of a DNA barcode library for Australian Lepidoptera revealed that Oenochroma vinaria Guenée, 1858, as currently understood, is actually a mix of two different species. By analyzing DNA barcodes from recently collected specimens and the 150 year-old female lectotype of O. vinaria, we propose a reliable assignment of the name vinaria to one of these two species. A lectotype is designated for Monoctenia decora, a confirmed synonym of O. vinaria, and a new species, Oenochroma barcodificata sp. nov., is described. This species is only known from Tasmania and New South Wales; its biology and immature stages are described in detail.
