A specimen collected from the Beibu Gulf in October 2016 was identified as Taeniopsetta ocellata (Günther, 1880) belonging to genus Taeniopsetta (Pleuronectiformes: Bothidae). Such genus and species are reported for the first time from the coastal waters of mainland China. Characters of genus Taeniopsetta mainly include the following: body ovate; both eyes on the left side of body; mouth rather small; teeth uniserial on both sides; scales small, lateral line only on ocular side, absent on blind side; one strong rostral and two or three orbital spines present in males, feeble or absent in females; first ray of ventral fins on the blind side opposite to the second ray on the ocular side; base of ventral fins short; and some of the rays of the dorsal and anal fins prolonged into filaments. The diagnostic features of T. ocellata are as follows: pectoral fins unequal on both sides; the 13th to 17th dorsal-fin rays and six anterior rays of anal fins elongated and filamentous in males; 2~4 irregular V-shaped or semicircular hollow blotches within yellow spots on the upper and lower body on the ocular side.
