CUCULLANUS-PALMERI N-SP (NEMATODA, CUCULLANIDAE) FROM THE BATFISH OGCOCEPHALUS-NASUTUS IN THE GULF-OF-MEXICO

Cucullanus palmeri n. sp. is described from the shortnose batfish, Ogc ocephalus nasutus, in the Gulf of Mexico. This species is anatomically most similar to Cucullanus gendrei but differs from it In having a sh orter esophagus and longer tail. Males differ in having a smaller gube rnaculum and a different arrangement of a lateral caudal papilla. Cucu llanus palmeri is readily distinguished from Cucullanus lophii, also f rom a lophiform fish host, in that the deirids and excretory pore are not posterior to the posterior end of the esophagus like in C. lophii.
