摘要

Discobothrium caribbensis sp. n. (Lecanicephalidea) is described from the spiral valve of the yellow- spotted stingray, Urolophus jamaicensis from Jamaica. The new species is the only member of the genus described with four testes. It is most similar in number of testes to D. japonicum Yamaguti, 1934, which has six testes and a myzorhynchus. A myzorhynchus is absent in D. caribbensis.
