Redescription of the serranid perchlet Chelidoperca pleurospilus (Günther, 1880).

Chelidoperca pleurospilus (Günther, 1880) (Perciformes: Serranidae) is redescribed on the basis of the lectotype (designated herein) and 69 non-type specimens from the eastern Indian and western Pacific oceans, ranging from the Andaman Sea east to New Caledonia, and northwestern Australia north to Japan.
