Abstract
A single specimen of Parapercis randalli Ho and Shao, 2012, previously known only from the type locality (Taiwan), was collected from Yoron-jima island, Amami Islands, Kagoshima Prefecture, Japan. It represents the first record of the species from Japan and the northernmost record for the species. The specimen is described in detail and the new Japanese name “Homura-toragisu” is proposed. Parapercis randalli resembles P. basimaculata and P. rubromaculata, but differs from both in fresh coloration and the following morphological characters: greater pre-pelvic-fin length [26.3–27.7% of standard length (SL)], shorter longest soft dorsal- and anal-fin ray length (12.4–15.9% SL and 11.4– 13.1% SL, respectively), shorter pectoral-fin length (19.3–20.9% SL), shorter pelvic-fin length (18.0–22.2% SL) and shorter caudal-fin length (20.2–22.1% SL).
