Abstract
Two specimens of Pterygotrigla cajorarori Richards and Yato, 2012 (Perciformes: Scorpaenoidei: Triglidae) were collected from the Pacific coast, off Shizuoka Prefecture, one from Suruga Bay, and the other from Enshu Nada, Japan. The specimen from Enshu Nada is small (152.8 mm in standard length), lacking hyper-ossification on the rostral projection, and having characteristic coloration of small yellow ocelli scattered on the dorsal surface of the body and a small black blotch on the membrane between the second to third and the third to fourth rays of the second dorsal-fin. Until recently, this species had been collected in Japan only from Kochi Prefecture but, in the recent two years, it has been collected from Shizuoka Prefecture. We consider that this species has extended its distribution northward as a result of the increase in marine temperature. The specimen from Suruga Bay represents the northernmost distribution of this species.
