Four trematodes, all new host records, were found in synaphobranchid eels from the continental slopes in the Gulf of Mexico and the Straits of Florida. Hypertrema ambovatum Manter, 1960 (Fellodistomidae), previously known only from near New Zealand, is reported from Synaphobranchus oregoni, including data in addition to the original description; Pseudopecoelus vulgaris (Manter, 1934) (Opecoelidae) and Hirudinella sp. (Hirudinellidae) are reported from S. affinis and S. oregoni, respectively, and commented upon briefly; and Helicometra robinsorum sp. n. (Opecoelidae) is described from S. oregoni and Ilyophis brunneus. The latter trematode most closely resembles H. antarcticae Holloway and Bier, 1968, from which it differs by having a sucker-width ratio of 1:1.7 to 2.1 rather than 1:1.2, a subterminal rather than terminal oral sucker, a cirrus sac extending to the posterior border rather than middle of the acetabulum, and eggs that are usually smaller.
