Abstract

The nematode Cucullanus robustus Yamaguti, 1935 (Cucullanidae) is redescribed from specimens collected from the intestine of Conger myriaster (Brevoort) (Osteichthyes) collected off the southern coast of South Korea in September 2005. Examinations of its morphology by both light and scanning electron microscopy (latter used in this species for the first time) revealed the presence of a previously unreported unpaired median preanal papilla, and variations in the situa-tion of the excretory pore relative to the oesophagus end, as well as in measurements of some organs. The morphology of C. robustus was compared with that of other congeneric species described from anguilliform fishes. The finding of C. robustus in Korean waters represents a new geographical record for this parasite.
