Abstract

The genusLeptepsilonema is recorded for the first time from the Mediterranean:L. santii sp.n. is characterised by a slender body with a large number of annules (122–128). Cuticular ornamentation with clear ridges and a lateral field of small thorns on both sides of the anteriormost annules are also typical as well as the number and arrangement of copulatory thorns (2–3 pairs, 2 fields), the shape and length (49–58 µm) of spicules in males.L. filiforme is recorded from New Caledonia; specimens largely resemble the original types but are larger. The variability of some morphological structures is discussed.
