Two new species of Sabatieria Rouville (Nematoda: Comesomatidae) with conical-cylindrical tails, from Campos Basin, Rio de Janeiro, Brazil

Abstract

Sabatieria is the most abundant nematode genus on the Campos Basin continental slope. Two new species are described here. Sabatieria exilis sp. n. has a small rounded head and a narrow pharynx with a cuticularized anterior end. Sabatieria fidelis sp. n. has a short outstretched testis, spicules directed ventrally and shaped like the tip of a dropper, the gubernaculum with a v-shaped cuticularized area in the distal part, short cephalic and somatic setae, and a longer tail.
