| Abstract |
Three new Xyalidae species are described from Algoa Bay, South Africa. Gonionchus africanus sp. n. is characterized by the anterior position of the amphid, absence of longitudinal cuticular ornamentation, the conical tail and the peculiar shape of the gubernaculum. Both Xyala aestuariensis sp.n. and Xyala psammonalis sp. n. have a heavily sclerotized buccal cavity and numerous (more than 40) longitudinal striae on the cuticular annules. Xyala imparis Boucher and Helleouet, 1977 and Xyala striata Cobb, 1920 are redescribed from the Southern Bight of the North Sea. Omicronema Cobb, 1920 is synonymized with Xyala Cobb, 1920 and the genus Xyala is redefined. |
