Description

One adult (184.1 mm in standard length) and three postflexion larvae (9.9-18.1 mm in standard length) of the telescope fish, Gigantura indica Brauer, 1901, which has not previously been treated as Japanese fishes, were collected off south-east Kyusyu and east of Boso Peninsula, respectively. Descriptions based on these specimens are provided and a new Japanese name for the species proposed. Gigantura indica is distinguishable from the only other confamilial species (Gigantura chuni Brauer, 1901) by the numbers of anal fin (11-14) and pectoral fin rays (36-43), and several body proportions (e.g., caudal peduncle depth). The above specimens are the northernmost records of G. indica from the western North Pacific. The occurrence of postflexion larvae from east of Boso Peninsula (Kuroshio Extention region) is a firm indication that the species reproduces in waters associated with the Kuroshio Current.
