( Fig. 4 J : Table 4)

Material. Male; registration number CNP NEM 650.

Locality. Mirage , San Julián Bay, Santa Cruz province, Argentina. Coordinates: 49°18’S, 67°42’W; water depth: low littoral. Collected by Catalina Pastor , 12 January 2009 .

Discussion. The Argentinian specimen found resembles the description of C. gerlachi Timm, 1961 in the general shape of the body, length of cephalic setae, shape, width and position of the amphidial fovea, de Man’s ratios, shape of the spicule, gubernaculum and tail and ventral buccal cavity. It differs in the presence of two precloacal papillae, a character not found in the original descriptions probably overlooked.
