Abstract
In the Campos Basin, 12 species of Sabatieria were collected, 2 of which were new to science. Sabatieria labium sp. nov. is characterized by well-defined lips and a spiral amphideal fovea with 4.25–4.5 narrow turns, combined with cephalic setae 3 µm long and 7–8 small, pore-shaped supplements, gradually spaced further apart anteriorly. Sabatieria verteris sp. nov. possesses 8–10 minute, pore-shaped precloacal supplements, gradually spaced further apart anteriorly, and short, slightly sclerotized spicules. Additionally, redescriptions of Sabatieria flecha, S. fidelis, S. mortenseni, S. ornata and S. paracupida are presented. The collection of additional specimens of these species allowed a re-evaluation of morphological and/or morphometric variations.
