Maximum-likelihood of phylogenetic tree of different specimens in the G. pacifica assemblage with D. diesingiana as the outgroup. Seasonality for each specimen in the G. pacifica assemblage is highlighted in bold. The analyzed matrix merely includes 669 shared characters (i.e., nucleotides) due to the incomplete rbc L sequences for the specimen from Small Port, KNP, and southern Taiwan. Statistical supports are shown on branches. The value is 100 replicates of bootstrapping proportion values (> 50%) using ML analyses.
