Fig 5. Species delimitation according to the generalized mixed Yule coalescent (GMYC) single-threshold model using COI data set.

Fig 5

A. Lineage-through-time plot based on the ultrametric tree obtained from COI sequences. The sharp increase in branching rate, corresponding to the transition from interspecific to intraspecific branching events, is indicated by a red vertical line. The x- axes (both in panels A and B) show substitutions per nucleotide site. B. Likelihood function produced by GMYC to estimate the peak of transition between cladogenesis (interspecific diversification) and allele intraspecific coalescence along the branches. C. F. tonkinensis+L. rufiantennus subclade of the ultrametric tree. D. F. viridifemorata group subclade of the ultrametric tree.
