WA Museum Records and Supplements | Updated 1 decade ago

Abstract - Neopomacentrus aquadulcis, new species is described from 40 specimens, 15.1-45.7 mm SL, collected from the tidal reaches of freshwater streams in Milne Bay and Morobe provinces. It is clearly separable from other members of the genus on the basis of its very dark overall coloration and characteristic, broad-lobed caudal fin shape. It is also the only Neopomacentrus possessing a blackish caudal fin compared to the yellow (or yellow with dark margins) caudal fin seen in other members of the genus. It is only the fourth pomacentrid species known to occur in freshwater.
