Speciation of Euphaea damselflies.

Allopatric speciation has been a dominant geographic mode of speciation over several decades. Allopatric mode of speciation emphasizes the prominent role of physical barriers and restriction of gene flow upon divergence. Gene flow is often considered as an impediment for speciation. A few recent studies, however, showed that speciating process can proceed in the face of gene flow. Thus, it raises the issue that whether the importance of physical barriers in species formation has been overemphasized. In this study, we used two morphologically similar pairs of Euphaea damselflies, E. formosa and E. yayeyamana, E. decorata and E. ornata, to investigate the amount of historical gene flow occurred during their speciational process. Euphaea formosa, E. yayeyamana, and E. ornata are each endemic island species of Taiwan, Ishigaki and Iriomote of Japan, and Hainan of China, respectively. Euphaea decorta is a continental species distributed in Vietnam and Southeast China. The reconstructed phylogeny based on cox2, ITS, and arr genes suggested that E. formosa and E. yayeyamana, as well as E. decorata and E. ornata, are both valid sister species pairs. We then used the ‘Isolation with Migration’ (IM) model to estimate the effective population sizes (θ), migration rates (m), and divergence times (t) of these two species pairs using two mitochondrial and ten nuclear loci. These population genetic parameters were estimated to test the predictions based on a strict allopatric hypothesis (i.e. m1 = m2 = 0) versus a speciation with gene flow model (i.e. m1 ≠ m2 ≠ 0). Our results showed that the existence of asymmetric gene flow between E. formosa and E. yayeyamana, as well as E. decorata and E. ornata. The estimated gene flow from E. formosa to E. yayeyamana and from E. decorata to E. ornata were both higher than the reverse. The effective population sizes of E. formosa and E. decorata are larger than that of E. yayeyamana and E. ornata, respectively. The divergence time of E. decorata and E. ornata are more recent than that of E. formosa and E. yayeyamana. In contrast to previous studies of island endemics, which usually conclude an allopatric mechanism, our study of island damselflies rejects a strict allopatric model and further suggests that speciation with gene flow may play a more important role on diversification of island taxa. Further studies thus should focus on identifying the potential ecological selection in promoting divergence of these island damselflies.
