This dataset contains the digitized treatments in Plazi based on the original journal article Amaoka, Kunio, Su, Yo, Ho, Hsuan-Ching (2026): A new lefteye flounder of the genus Crossorhombus (Teleostei, Bothidae) from Penghu Islands, western Taiwan. ZooKeys 1273: 15-25, DOI: 10.3897/zookeys.1273.167628AbstractA new lefteye flounder, Crossorhombus pescadores sp. nov., is described based on five specimens collected from Penghu Islands. This new species differs from the other four congeners by having a pair of small black spots on the caudal fin, a horizontal triangular bluish-black marking on the blind side of body in male, the front wings of the marking reaching the base of dorsal and anal fins, and a combination of morphometric characters, including a larger head, deeper body, smaller eyes, fewer dorsal- and anal-fin rays and lateral-line scales, and other characters. A key to all five nominal species of Crossorhombus is provided.
