Nematodes of the order Dorylaimida from Romania. The genus Enchodelus Thorne, 1939. 2. Species with rounded tail and medium-sized odontostyle.

Four species of the genus Enchodelus, one new and three known, from natural areas in Romania are studied. Enchodelus parahopedoroides sp. n. is distinguished by its 1.44-1.64 mm long body, lip region offset by a marked depression and 17-18.5 μm in diam., odontostyle 26-29 μm or 1.5-1.6 lip region diam. long and 1.6-2.0% of total body length, odontophore 40-43 μm long and with distinct basal knobs and flanges, neck length 300-328 μm, pharyngeal expansion 120-130 μm long or 39-41% of total neck length, female genital system amphidelphic, uterus long and tripartite, pars refringens vaginae with two trapezoidal sclerotisations, V= 45-52, tail rounded conoid (20-24 μm long, c = 63-80, c′ = 0.6-0.8), spicules 59-67 μm long, and nine spaced ventromedian supplements starting shortly in front or at level of anterior end of spicules. Enchodelus lucinensis and E. ponorensis are redescribed based on a study of type material. Measurements and additional data are provided for E. longispiculus, which is reported from Romania for the first time. [ABSTRACT FROM AUTHOR]
