Nematodes of the order Dorylaimida from Andalucía Oriental, Spain. The genus Enchodelus Thorne, 1939. 3. Description of two new and one known species with rounded tail and medium-sized odontostyle

Abstract Two new and one known species belonging to the genus Enchodelus from the southeast of the Iberian Peninsula are described and illustrated. Enchodelus ameliae sp. n. is a medium-sized nematode (1.37-1.55 mm) with lip region offset by constriction, odontostyle 30-32 μm long, female reproductive system amphidelphic with tripartite uterus, vulva almost equatorial (V = 47-50), spicules 49-60 μm long, 11-14 spaced ventromedian supplements and short rounded conoid tail. Enchodelus longispiculus sp. n. is characterised by its medium-sized body (1.32-1.87 mm), lip region offset by shallow depression, odontostyle 27-31 μm long, female reproductive system amphidelphic with tripartite uterus, vulva pre-equatorial (V = 41-48), spicules 63-72 μm long, 8-14 spaced ventromedian supplements and short rounded conoid tail. Enchodelus hopedoroides is redescribed on the basis of Andalusian material and observations on the Swiss holotype. These three species share some features, such as medium-sized odontostyle (ca 30 μm long), tripartite uterus and short, rounded, tail. They are compared in detail with other similar species, namely E. altherri, E. analatus, E. arcticus, E. georgiensis, E. hopedorus and E. ponorensis. A key to their identification is provided.
