沖縄島で採集された日本初記録のヒカリキンメダイ科オオヒカリキンメPhotoblepharon palpebratum

抄録

A single specimen of Photoblepharon palpebratum (Boddaert, 1781), formerly limited to the tropical western Pacific, was collected from Okinawa Island, Japan at a depth of 1 m. The specimen was characterized by the following combination of characters: single dorsal fin with 3 spines; a black shutter lifting to cover the subocular organ; a large white spot on the dorsal corner of the opercle; pelvic-fin rays I, 6. The tiny first dorsalfin spine was identified from a radiograph. The specimen represents the first record of P. palpebratum from Japan and is the northernmost record of the species. The specimen produced a total of 273 eggs, but those were probably postmaturity.
