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, Ogcocephalus nasutus, in the Gulf of Mexico. This species is anatomically most similar to Cucullanus gendrei but differs from it in having a shorter esophagus and longer tail. Males differ in having a smaller gubernaculum and a different arrangement of a lateral caudal papilla. Cucullanus palmeri is readily distinguished from Cucullanus lophii, also from 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.
