利用mtDNA 12 S和16 S rRNA序列以及cyt-b基因对来自印度、孟加拉国、泰国、老挝、中国、台湾和日本琉球群岛的装饰姬蛙（Microhyla ornata）进行了系统发育研究。本种内有两个独立的分支，一个由来自印度和孟加拉国的种群组成，另一个包括其余的种群。在后一个分支中，来自琉球群岛的种群与其他种群（来自台湾和大陆的种群）明显分离，具有相当程度的遗传分化。这三个谱系中的每一个都被认为是代表了一个好的物种，而装饰姬蛙这个名字仅限于南亚种群。对于来自台湾和从中国到东南亚的广泛地区的种群，应使用Microhyla fissipes的名称，而琉球种群最适合称为Microhyla okinavensis，尽管在这最后一个物种中的一些岛屿群种群之间存在进一步的实质性遗传分化。
A molecular phylogenetic survey was conducted using mtDNA sequences of 12S and 16S rRNA, and cyt-b genes to examine taxonomic relationships among populations of the Pan-Oriental microhylid, Microhyla ornata, from India, Bangladesh, Thailand, Laos, China, Taiwan, and the Ryukyu Archipelago of Japan. Two discrete clades are recognized within this species, one consisting of populations from India and Bangladesh, and the other encompassing the remaining populations. In the latter clade, populations from the Ryukyu Archipelago are clearly split from the rest (populations from Taiwan and the continent) with considerable degrees of genetic differentiations. Each of the three lineages is judged to represent a good species, and the name Microhyla ornata is restricted to the South Asian populations. For the populations from Taiwan and a wide region from China to Southeast Asia, the name Microhyla fissipes should be applied, whereas the Ryukyu populations are most appropriately referred to as Microhyla okinavensis, although further substantial genetic differentiations are recognized among some island group populations within this last species.
