Abstract

Four new species of the genus Perepsilonema are described. They are characterized by general habitus, cuticular ornamentation, shape and sexual dimorphism of the amphideal fovea, shape and number of ventral copulatory spines and the shape of the spicules. The female genital system comprises two reflexed ovaries, a left and a right spermatheca and a median uterine chamber filled with sperm cells. The distal part of the uteri have secretory wall cells which contain in some specimen spherical refractive bodies.
