In a study investigating the composition and spatial and temporal variation of the benthic macrofauna associated to the discharge of domestic sewage off Fortaleza, north-eastern Brazil, a new species ofSylliswas found. This new species,S. guidaesp. nov., is characterized by having blades of falcigers with subdistal tooth about same length as distal tooth, but stouter than it, with spines on cutting edge almost reaching the tip of subdistal tooth, blades of falcigers with conspicuous subdistal triangular process and unusually long anal papilla between anal cirri, measuring about one-quarter of their length.Syllis guidaesp. nov., is herein described and compared with the most similar congeners.

Four new nematode species are described: Theristus quadripapillatus, sp. nov., distinguished from all known species of the genus in possessing four genital supplements, in the structure and shape of the gubernaculum, and in possessing a glandular tube parallel with the anterior testis and opening into the vesicula seminalis; Acanthopharynx distechei, sp. nov., characterized by its head shape with smooth helmet bearing 24 subcephalic setae, by the elongated loop-shaped amphids, and in males by possessing only one pre-anal papilla; Ptycholaimellus lizardiensis, sp. nov., characterized in males by the shape of the gubernaculum with two lateral pieces with an enlarged, dentated distal end, and by the presence of a small pre-anal papilla; and Paracanthonchus parahartogi, sp. nov., characterized by having an outer circle of 10 minute setose sense organs, by having a very small tooth, and in males by the shape of the copulatory apparatus and the six pre-anal supplements. For four known species additional information is given: Paracomesoma dubium (Eilipjev, 1918) Stekhoven, 1950; Actinonema longicaudatum (Steiner, 1918) Wieser, 1954 ; Halichoanolaimus quattuordecimpapillata Chitwood, 1951; and Bathylaimus australis Cobb, 1894.
