DNA barcode. The COI gene was amplified and sequenced for three specimens, which were subsequently assigned GenBank accession numbers: O1: PV351610, O3: PV351611, and O4: PV351612. Distribution. Southeastern to south-central China (Guangdong, Guangxi, Yunnan, Fujian, Zhejiang, Hainan, Jiangxi, Guizhou, Hunan); northern Vietnam (Ha Giang, Nghe An, Hoa Binh, Vinh Phuc); northern Laos (Xam Neua). Our specimens from Hainan represent the first provincial record of O. platynota. Additionally, while scattered literature (Fujita 2010; Maruyama 2024; Mizunuma & Nagai 1994) mentions O. platynota in Sichuan Province, these are limited to a few historical reports with no recent corroboration. Given the species’ core distribution across eastern Indochina and southeastern to south-central China, we consider reports of O. platynota in western China’s Sichuan Province biogeographically implausible. These isolated historical records likely represent fake data.
