Summary:
A dark bluish-grey damselfish shading to a white tail with darker scale margins forming a network pattern on the body, a large black spot covering the pectoral-fin base and pectoral-fin axil, and a narrow dark margin on the tail.
This species is currently only known from reefs in the Coral Sea in the Australian EEZ. Images in many publications are of Pomacentrus flavioculus, from Fiji and Tonga, which has a yellow tail.

Imitator Damsel, Pomacentrus imitator (Whitley 1964)

More Info


Distribution

Endemic to reefs in the Coral Sea in the Australian EEZ. The type material was collected "from beyond the reef crest".

Remarks

The similar Pomacentrus flavioculus (from Fiji and Tonga) differs from P. imitator in the following characteristics: a bright yellow ring that encircles the pupil, a more uniform body color (vs. contrasting pale scale centers and dark scale margins in P. imitator), a yellowish caudal fin (vs. whitish in P. imitator), and a small orange marking immediately above the large black spot that covers the pectoral-fin base (absent in P. imitator).
