Abstract Aim Similar environmental selection pressures drive the occurrence of convergent evolution among species. However, studies on this phenomenon are scarce at the population level. Here, we used two waist‐shaped bugs to test the hypothesis that similar high‐elevation habitat environments could lead to similar genetic adaptations among populations of different species. Location East Asia. Taxa Malcus sinicus Štys, 1967 & Malcus insularis Štys, 1967. Methods Population genetic structure was determined by phylogenetic and phylogeographical analyses. Demographic history was inferred by comparing simulated history models. Suitable habitat from the last interglacial period (LIG) to the present was predicted by ecological niche modelling (ENM). Convergent evolutionary processes were jointly assessed by the comparison of population ecological differences and the principal component analysis of environmentally related single‐nucleotide polymorphisms (SNPs). Results Our results showed that the land bridge in the Pleistocene helped ancestral populations of M. sinicus and M. insularis diffuse from mainland China to Taiwan Island. Subsequently, the geographical barrier imposed by the Taiwan Strait promoted the species differentiation. Geographic isolation and adaptive evolution jointly promoted the population differentiation in M. sinicus . Genetic similarity was found between the populations of M. sinicus in southwestern China (sin‐YN) and M. insularis on Taiwan Island (ins‐TW)...
