ABSTRACT
A nematode species belonging to the genus Cosmocephalus was collected from the stomach of 2 common gulls, Larus canus. The common gulls were found dead on the seaside of Gangneung City, the Republic of Korea. The worms were identified and classified by light (LM) and scanning electron microscopy (SEM) on the basis of important taxonomic characters. The nematodes were characterized by a body length 9.1-9.3 mm (males) and 15.5-15.9 mm (females) and cordons recurrent in anterior direction and anastomosing laterally at about the level of anterior quarter of the buccal cavity. The salient bicuspid deirids were located on the posterior to the cordons. Lateral alae were well-developed, extending from the level just posterior of deirids to the level about middle of the body. LM and SEM observations identified the worms as C. obvelatus. This is the first reported case of C. obvelatus infection in common gulls in Korea.

Mentions: Measurements of this medium-sized acuariids are shown in Table 1. Two pseudolabia were observed at lateral side of the mouth with each bearing a pair of large cephalic papillae and 1 inconspicuous amphid (Fig. 1B). Cordons arose dorsally and ventrally between pseudolabia (Figs. 1A, B,2B), extending posteriorly in longitudinal direction and anastomosing laterally at about the level of the anterior quarter of the buccal cavity (Fig. 1B). Each cordon consists of a single row of cuticular plates (Fig. 1A, C). The salient bicuspid deirids were located on the posterior to cordons (Figs. 1D,2C). Lateral alae well-developed, extending from level just posterior of deirids to level about the middle of the body (Fig. 1D, E).
