Abstract

Syringolaimus is the most abundant and diverse genus of the family Ironidae (Nematoda) found in the Campos Basin, off Rio de Janeiro, Brazil. In this article, four new species of this genus are described. S. annae sp. n. is characterized by a conical-cylindrical tail without a spinneret. S. magdae sp. n. possesses a pair of ejaculatory glands located in the precloacal region, and a spinneret, which comprises 21.2% of the total tail length. In S. smolae sp. n. the spicule is setiform. S. taniae sp. n. has the anterior region of the tail rounded, with its terminal portion cylindrical-filiform.
