3.3. Examination of Serpinema magathi and Serpinema monospiculatus

We evaluated specimens of S. magathi and S. monospiculatus deposited at CHIOC. The morphology of these specimens agrees with Freitas and Dobbin Jr. (1971) descriptions. Serpinema magathi has 9–11 ridges on the buccal capsule, 14 pairs of caudal papillae, and a single spicule ending in a bifid tip; while S. monospiculatus has 10–12 ridges on the buccal capsule, 10 pairs of caudal papillae and a single spicule with sharpened end. We did not observe a sheath covering the spicule in both species.
