Abstract
Gorgoderina diaster, Cylindrotaenia americana and Ophiotaenia bonariensis are reported, and C. lynchi and G. robustus described from B. marinus from 3 localities in the Republic of Colombia. All are new locality records and B. marinus is a new host for G. diaster and C. americana. C. lynchi differs from C. creptotrema in possessing smaller eggs, relatively smaller oral papillae and suckers, and elongate rather than sperhical testes. G. robustus differs from all other species in the genus in possessing a pharynx which is significantly larger than the acetabulum and tegumental spines restricted to the anterior 5th of the body. It further differs from G. facioi in possessing diagonal testes and slightly smaller eggs and from G. palmipedis in possessing an I-shaped excretory vesicle and slightly smaller eggs. The known species of amphibian platyhelminths from Colombia have affinities with both North and Central as well as South America.
