One example. This species is closely related to Pomacentrus violascens 

 (Bleeker). It differs however in the almost uniform dark color, without any yellow 

 or golden on lower regions or caudal peduncle. Ventrals also differ, as they are 

 entirely dark like the other fins, except tip of first or longest ray which is pearl- 

 white beyond tip of spine. 



(AevKoo-c^Dpo?, white-footed, with reference to the white-tipped ventrals.)
