Sebastiscus vibrantus, a new species of rockfish (Sebastidae) from Indonesia and Taiwan


A new species of rockfish, Sebastiscus vibrantus, is described on the basis of 24 specimens collected from Bali, Indonesia and Taiwan. Although closely resembling Sebastiscus tertius (Barsukov and Chen 1978) in overall body appearance, and having usually 19 pectoral-fin rays and black margined white blotches scattered on the lateral body surface, the new species has thicker unbranched pectoral-fin rays, a greater pectoral-fin base length, the third dorsal-fin soft ray usually longest, the anterior margin of the scaled suborbital area not reaching level the anterior margin of the orbit, and weakly developed nuchal spines.
