Acanthoplesiops cappuccino, a new species of acanthoclinine fish from the Red Sea (Teleostei: Plesiopidae)

Abstract

Acanthoplesiops cappuccino is described from the 16.4 mm SL holotype collected from Jeddah, Saudi Arabia, Red Sea. The following combination of characters distinguishes it from congeners: dorsal-fin rays XVIII,4; anal-fin rays VII,4; pectoral- fin rays 18; caudal fin not connected to last rays of dorsal and anal fins by membrane; and caudal peduncle with a pale yellowish brown bar, which extends broadly on to caudal fin. An underwater photo of the anaesthetised holotype is provided, as well as one of the freshly dead holotype and only known specimen of the similar species A. naka. Tables summarizing diagnostic characters of the six known species of Acanthoplesiops are included. Copyright © 2013 Magnolia Press.
