CANADA. Abstract. - Fowler (1934) described Nematops chui from only one specimen captured off Luzon, in the Philippines. Comparing this specimen with other Nematops (except N. macrochirus Norman, 1931), Fowler distinguished N. chui by three characters: body height almost 3 times the standard length; 48 scales on lateral line; and only one tentacle on the lower eye. We compared the N. chui holotype with specimens of N. macrochirus (including the type specimens) and we found that N. chui has a body height similar to N. macrochirus. Also, the scale number on the lateral line of the N. chui holotype is roughly 58 (not 48) and this value is found within the limits of the values for N. macrochirus. Finally, the specimens of N. macrochirus examined (N = 37) had a tentacle on the two eyes, an eye only or no tentacle at all, which eliminates the third diagnostic character from N. chui. As we could not find other characters proper to N. chui, we conclude that it is a junior synonym of N. macrochirus. Résumé.
