Gen. Simonus Ritsema, 1881

N.B.: Roewer (1955b: 601) listed Ctenonima Franganillo, 1946 as a corinnine genus (for unknown reasons, as Franganillo's description immediately follows one of a Syrisca species under a "Liocraninae" heading). However, Franganillo did not describe a new genus for the species he described as Ctenonima cubana, and evidently did not intend to do so. His statement (1946: 102) that "Dice E. Simon que la única especie del género es de Nueva Caledonia" indicates that Ctenonima is merely a lapsus for Ctenomma Thorell, 1890, which was listed in Simon's Histoire naturelle as having a single species, from New Caledonia (Franganillo's only illustration for the species, of the eye pattern, shows a ctenid-like arrangement); Ctenomma was placed as a junior synonym of Simonus and transferred here from the Ctenidae by Lehtinen, 1967: 264.
