Comment(s) on data
Carvacho (1982: 18) - On la signale souvent associé à des espèces de Pinna. - Host record (cf. Fransen, 2002, Zool. Verh.) - Recorded inside the gill cavity of Pinna carnea (Gmelin, 1791) (cf. Criales, 1984; Rodriguez, 1980; present records), Atrina seminuda (Lamarck, 1819) (present record), Pinna rigida (Lightfoot, 1786) (present record), and from unidentified specimens of Pinna (cf. Holthuis, 1951a).
Fransen (2002, Zool. Verh.) - P. mexicana is closely related to P. pinnophylax. Actually their is no clear distinction between the species regarding their morphology or in the colour pattern. (P. pinnophylax is from East Atlantic).
The host mentioned for a specimen from Bonaire by Holthuis (1951; Ophiuroid Astrophyton muricatum) is unusual; Fransen (200: 145) indicates that the corresponding specimen was not located in the RMNH collection.
