by Gerald R. Allen, Mark V. Erdmann and Ni Putu Dian Pertiwi – aqua 28 (1) pp. 1-26 Three new species of Pomacentrus, allied to P. philippinus, are described from the eastern Indian and western Pacific oceans. The current study, our third dealing with the P. philippinus group of species, concludes that it contains at least 10 allopatric species, which are mainly separable on the basis of colour pattern, slight meristic differences, and in most cases, mitochondrial DNA (mtDNA) evidence. Pomacentrus umbratilus n. sp. is described on the basis of 27 specimens, 15.0-80.5 mm SL from the East Andama ..read more
