Losaria coon (Fabricius, 1793) is currently comprised of ten subspecies, which were originally described under two names, Papilio coon and P. doubledayi before 1909, when they were combined as one species. The main difference between them is the colour of abdomen and hindwing subterminal spots—yellow in coon and red in doubledayi. Wing morphology, male and female genitalia, and molecular evidence (DNA barcodes) were analysed for multiple subspecies of L. coon and three other Losaria species—rhodifer, neptunus, and palu. Our molecular data support the separation of L. coon and L. doubledayi stat. rev. as two distinct species, with L. rhodifer positioned between them in phylogenetic analyses. Wing morphology and genitalic structures also confirm the molecular conclusions. Our findings divide L. coon into two species occupying different geographic ranges: with L. coon restricted to southern Sumatra, Java, and Bawean Island, while L. doubledayi occurs widely in regions from North India to northern Sumatra, including Hainan and Nicobar Islands. Hence, future conservation efforts must reassess the status and threat factors of the two species to form updated strategies.

黄色和红色标记的Club-Tail Losaria浣熊是同一物种吗？

Losaria浣熊（Fabricius，1793年）目前由十个亚种组成，最初以两个名字进行描述，Papilio浣熊和P. doubledayi于1909年合并为一个物种。它们之间的主要区别是腹部和后侧的子末端斑点的颜色-浣熊黄色，双大叶猴红色。翼形态，雄性和雌性生殖器，以及分子证据（DNA条形码）分析了L. coon和其他三个Losaria物种的多个亚种-Rhodifer，neptunus和palu。我们的分子数据支持L. coon的分离和L. doubledayi 统计。转速 作为两个不同的物种，在系统发育分析中将杜鹃花置于它们之间。机翼的形态和生殖器结构也证实了分子结论。我们的研究结果将浣熊分为两个物种，分别占据了不同的地理范围：浣熊局限于苏门答腊南部，爪哇岛和巴旺岛，而doubledayi则广泛存在于印度北部至苏门答腊北部，包括海南和尼科巴群岛。因此，未来的保护工作必须重新评估两个物种的状况和威胁因素，以形成更新的策略。
