The Ryukyu island arc, originally a continental margin arc, separated from the Chinese continent by the rifting of the Okinawa trough, a process which began at 1.55 million years ago (Ma) and continues to the present. In addition, the Ryukyu arc was simultaneously divided into the northern Amami-Okinawa and southern Yaeyama islands by the Kerama rift valley, and consequently formed two isolated island units. The Kuroshio warm current began to flow into the Okinawa trough from the Yonaguni Strait, and flow out through the Tsushima and Tokara straits also at 1.55 Ma, and these seaways effectively acted as barriers between the Ryukyu islands and Taiwan, China and Japan. Through this geological process, vicariant speciation generated Ryukyu endemic animal species. We support this hypothesis by drawing linearized maximum likelihood (ML) phylogenetic trees of the species in four endemic insect groups (peacock butterfly, Chinese windmill butterfly, golden-ringed dragonfly, window firefly) using GenBank sequence data. We determined the precise branching ages for these phylogenetic trees, and show simultaneous speciation at 1.55 Ma for Amami-Okinawa and Yaeyama units. The Taiwan and Tsushima straits, barriers between Taiwan and China, and Japan and Korea, respectively, did not form sufficient barriers to migration during glacial low stands, and species were intermingled. A marine embayment may have posed as a migration barrier between northern and southern China in the Quaternary or a little earlier. From our study we also estimate the precise molecular evolution rate and justify the molecular clock.

“…). Firefly evolution is considered to be toward the loss of adult luminescence (Stanger‐Hall, Lloyd & Hillis, ; Oba, Branham & Fukatsu, ). However, the reason for this basic evolutionary process is uncertain and cannot be resolved based on the present analyses, although it may be related to the beginning of glacial–interglacial cycles and of four distinct seasons during the Quaternary.…”

We performed molecular phylogenetic analyses based on the mitochondrial COI gene (687 bp) and the nuclear 28S rRNA gene (715 bp) and reconstructed phylogenetic trees of the Pyrocoelia fireflies in the Ryukyu Islands and eastern Asia. Age calibration was done using a robust geological constraint: the Okinawa trough and associated straits began to rift at 1.55 Ma, isolating the Ryukyu Islands from the Chinese continent, Japanese islands, Taiwan island and some of the islands from each other. We suggest that the physical isolation of these islands began to generate the allopatric speciation within these islands, so the timing of this isolation was assigned to an appropriate node. The topology is completely concordant among phylogenetic trees reconstructed using MEGA (maximum-likelihood), raxmlGUI (maximum-likelihood) and BEAST (Bayesian inference; including combined analysis of COI and 28S rRNA genes). Two lineages are recognized, related to their emergence time; spring to summer, and autumn. In each lineage, vicariance is inferred to have begun at 1.55 Ma from our phylogenetic and geological analyses. In lineage 1, P. oshimana (Amami), P. matsumurai (Okinawa), P. discicollis (W. Japan), P. fumosa (E. Japan) and P. abdominalis (Yaeyama) were differentiated. In lineage 2, P. rufa (Tsushima and Korea), P. miyako (Miyako-jima), P. atripennis (Ishigaki-jima) and P. praetexta (Taiwan and HongKong) were differentiated. Pyrocoelia analis (Taiwan and China) emerges throughout the year except for winter, and constitutes another lineage. We suggest that Pyrocoelia fireflies differentiated at 2 Ma to generate these three lineages. The base substitution rate for the COI gene is estimated as 4.48% Myr -1 and that for the 28S rRNA gene is 0.394% Myr -1 , and these rates were used in a combined BEAty analysis in BEAST.
