The molecular phylogeny of 24 Oecophylla smaragdina populations and two O. longinoda populations was studied using 647 bp of the mitochondrial cyt b gene. The phylogenetic analysis suggested that O. smaragdina and O. longinoda were separated from each other first, and after that the first within-species divergence of O. smaragdina occurred in early stage of their history, in which the Asian, Australian, and Sulawesian groups rose. This grouping was almost coincident with the distribution of landmass in glacial periods in Pleistocene. Thereafter, each group seemed to have independently diverged into present populations on each landmass.
利用线粒体细胞色素b基因的647个碱基对，对24个黄猄蚁种群和2个长角立毛蚁种群进行了分子系统发育研究。系统发育分析表明，黄猄蚁和长角立毛蚁首先彼此分离，之后黄猄蚁在其历史早期发生了首次种内分化，形成了亚洲、澳大利亚和苏拉威西种群。这种分组几乎与更新世冰川期的陆地分布一致。此后，每个种群似乎在各自的陆地上独立分化为现在的种群。
