Cainocreadium lariosi

Martin, Storm B., Cutmore, Scott C., Ward, Selina & Cribb, Thomas H., 2017, An updated concept and revised composition for Hamacreadium Linton, 1910 (Opecoelidae: Plagioporinae) clarifies a previously obscured pattern of host-specificity among species, Zootaxa 4254 (2), pp. 151-187 : 172

Cainocreadium lariosi (Caballero y Caballero, 1946) Cribb, 2005

Synonyms: Emmettrema lariosi Caballero y Caballero, 1946; Hamacreadium lariosi (Caballero y Caballero, 1946) Yamaguti, 1953.

Records. From an unidentified marine fish, common name “merro”, off Oaxaca, Pacific coast of Mexico by Caballero y Caballero (1946).

Remarks. Caballero y Caballero (1946) proposed Emmettrema Caballero y Caballero, 1946 for this species, described from a single specimen. Yamaguti (1953) synonymised Emmettrema with Hamacreadium , but Cribb (2005a) transferred E. lariosi to Cainocreadium on account of the median genital pore. The view of Cribb (2005b) is accepted here. The common name of the original host suggests a grouper species of Mycteroperca Gill (Serranidae) .
