RODRIGUEZ-IBARRA, Erick; MONKS, Scott e PULIDO-FLORES, Griselda. Metacercariae of the type Paramonilicaecum (Digenea: Didymozoidae), accidental parasites in elasmobranchs (Elasmobranchii) from the Mexican Gulf of Mexico and identification of metacercarias (Didymozoidae) of the Colección Nacional de Helmintos. Rev. Mex. Biodiv. [online]. 2011, vol.82, n.2, pp.705-708. ISSN 2007-8706.
During an ongoing study of the helminths of stingrays (Elasmobranchii), 12 stingrays were collected from 3 localities in the state of Veracruz, Mexico: Laguna de Tamiahua, Laguna de Tampamachoco, and a costal reef in the Gulf of Mexico. Metacercarias were collected from the spiral valves of Dasyatis say (bluntnose stingray), Gymnura micrura (lesser butterfly ray), and Rhinobatus lentiginosus (Atlantic guitarfish). The metacercarias, accidental parasites, were assigned to type Paramonilicaecum (Digenea: Didymozoidae). Material (Didymozoidae) previously deposited in the Colección Nacional de Helmintos, Instituto de Biología, Universidad Nacional Autónoma de México, was re-identified. This is the first report of a species in larval phase of the "Type" Paramonilicaecum from the Gulf of Mexico, Veracruz, and the first report from a Mexican stingray.
