Ceratothoa retusa (Schiœdte & Meinert, 1883) is redescribed from the lectotype (here designated) collected from Mozambique, and the range is extended to include the Gulf of Suez in the Red Sea. Ceratothoa retusa is distinctive within the genus with a manifestly small head deeply immersed into pereonite 1, which has prominent, but variable, projecting anterolateral margins. Ceratothoa retusa has a tropical and subtropical Indian Ocean distribution, extending from eastern Africa (and now the Red Sea) eastwards to northern Australia and Indonesia. The only known hosts are the halfbeaks, Hemiramphus far (Forsskål, 1775) and H. robustus Günther, 1866 (Hemiraphidae).

Abstract (French): Ceratothoa retusa (Schioedte & Meinert, 1883) est redécrite à partir du lectotype (désigné ici) collecté au Mozambique, et sa répartition est étendue pour inclure le Golfe de Suez dans la Mer Rouge. Ceratothoa retusa se distingue à l'intérieur du genre par une tête manifestement petite, profondément enfoncée dans le péréonite 1, qui possède des bords antérolatéraux proéminents et saillants, mais variables. Ceratothoa retusa a une répartition tropicale et subtropicale dans l'Océan Indien, allant de l'Afrique orientale (et maintenant la Mer Rouge) vers l'Est jusqu'au Nord de l'Australie et l'Indonésie. Les seuls hôtes connus sont les Hemiramphidae, Hemiramphus far (Forsskål, 1775) et H. robustus Günther, 1866.
