In the process of speciation, divergent selection can either alter or maintain the level of differentiation between two populations. For two morphologically different subspecies, the divergence between them could either result from sexual selection favouring specific phenotypic traits (i.e. sexual selection hypothesis), or that individuals exhibiting alternative phenotypic traits have different fitness imposed by environmental variations (i.e. ecological speciation hypothesis). Two such sister subspecies of Psolodesmus mandarinus damselflies, northern P. m. mandarinus and central-southern P. m. dorothea were found in Taiwan. These two subspecies differ remarkablely in wing traits, indicating that sexual selection may favour wing traits specific to each subspecies, which could lead to divergent evolution. The different meteorological characteristics between their distributed areas may also alter natural selection favouring subspecies-specific phenotypic traits. From July to September in 2016, we marked and monitored 610 male P. m. mandarinus and 592 male P. m. dorothea. For each damselfly, we measured their body size indicators (i.e. weight, thorax width and length, abdomen length) and wing characteristics (i.e. wing length and wing width, indicating the overall size of the pigmented wings). The results of our generalized linear mixed models showed that within each subspecies, larger individuals have higher mating success and longer lifespan than smaller individuals, but no differences could be found in wing characteristics. These results suggested that, although these two subspecies diverged in their wing traits, their wing characteristics - or at least the overall size of the pigmented wing - were not likely to be the major component under the divergent selection in their speciation process.
