Complete cytochrome b gene sequences (1140 base pairs) in species of Megachiroptera were ascertained in order to deduce their phylogenetic relationships, using samples of Cynopterus brachyotis, Eonycteris spelaea, Ptenochirus jagori, Pteropus vampyrus, and Rousettus amplexicaudatus collected from the islands of Luzon and Mindanao in the Philippines. Genetic divergence between samples of R. amplexicaudatus, E. spelaea, and C. brachyotis was very small. On the other hand, a large genetic distance was detected between species of Megachiroptera. The phylogenetic tree using neighbor-joining, parsimony, and maximum-likelihood methods generated similar topologies, reflecting the evolutionary associations among megachiropteran species. We estimated that Megachiroptera separated from Microchiroptera 50.2 million years ago (MYA), and split further approximately 32.4 MYA, forming three lineages: E. spelaea, R. amplexicaudatus, and P. vampyrus and the P. jagori – C. brachyotis cluster. The third lineage, composed of P. vampyrus and the P. jagori – C. brachyotis cluster, branched out 31.9 MYA. We hypothesize that R. amplexi caudatus diverged from the three members of the subfamily Pteropodinae examined, and its phylogenetic relationship with E. spelaea remains unclear.
