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]

Six species of the genus Enchodelus, one new and five known, from natural areas in Romania were studied. Enchodelus transsilvanicus sp. n. is distinguished by its 1.28-1.51 mm long body, lip region moderately angular and 12.5-13.5 μm in diam., odontostyle 29-34 μm long or 2.1-2.6 times the lip region diam., odontophore lacking distinct flanges and 41-45 μm long or 1.2-1.6 times the odontostyle, neck length 272-298 μm, pharyngeal expansion 82-113 μm long and occupying 31-39% of total neck length, female genital system amphidelphic, uterus bipartite and 3.1-3.5 times body diam. at its level, pars refringens vaginae with two distinct sclerotisations, vulva a transverse slit (V = 45-48), female tail conical and regularly ventrad curved (42-47 μm, c = 28-36, c′ = 1.3-1.5), spicules 47-50 μm long, and 6-8 spaced, ventromedian supplements. Measurements, illustrations and additional data of the remaining five species are given, namely E. arcuatus, E. brevidentatus, E. geraldi, E. morgensis and E. veletensis. An emended diagnosis of E. arcuatus is provided. Three species, E. brevidentatus, E. morgensis and E. veletensis, are reported from Romania for the first time. [ABSTRACT FROM AUTHOR]

The article focuses on the identification of Labronema plica, Ciobanu, Popovici & Decraemer and a proposal for its transfer the genus Thonus Thorne. Labronema plica, described from a salt-affected area in Romania, is an interesting species because its general morphology also fits the Thonus patten. Reexamination of the species' type material showed a morphological pattern that is simialr to that of the genus Thonus and distibguishes it from Labronema.

Five Thonus species from Romania are described. Thonus montanus sp. n. is characterised by its body length of 1.56-1.90 mm, cuticle with coarse transverse striations, lip region 15-18 μm diam., odontostyle 20-22.5 μm long, plicate guiding ring, neck 400-553 μm long, pharyngeal expansion occupying 49-56% of total neck length, uterus 1-1.5 body diam. long, pars refringens vaginae with two separate pieces, gland cells present near vagina-vulva junction, vulva a short post-equatorial (V = 54-59) longitudinal slit, and female tail conoid (25-33 μm, c = 54-73, c′ = 0.8-1.2) with abundant blister-like structures and distinct hyaline portion. Thonus tenuistylus sp. n. is characterised by its body length of 1.17-1.56 mm, lip region offset by a more or less, usually well, marked constriction and 16-17.5 μm diam., slender odontostyle 17-20.5 μm long or 1.1-1.3 times lip region diam., neck 275-397 μm long, pharyngeal expansion occupying 42-52% of total neck length, female genital system amphidelphic, uterus bipartite and 1.7-2 body diam. long, pars refringens vaginae with two adjacent pieces, vulva a post-equatorial (V = 50-56) transverse slit, tail conoid-rounded (19-24 μm, c = 48.7-72.9, c′ = 0.8-1.0) and with abundant blister-like structures, spicules 38-43 μm long, and 3-6 widely spaced ventromedian supplements. Thonus sp. is characterised by its slender (a = 37.5) body 1.41 mm long, lip region practically continuous with adjacent body and 11.5 μm diam., odontostyle 10.5 μm long, neck 325 μm long, pharyngeal expansion 138 μm long or ca two-fifths of total neck length, a coarse ring-like structure surrounding cardia, female genital system amphidelphic, uterus ca 2.5 body diam. long, pars refringens vaginae with two adjacent trapezoidal pieces, vulva a transverse slit (V = 52), a pseudocoelomocyte present at mid-body, tail convex conoid (26.5 μm, c = 56, c′ = 1.1) with abundant blister-like structures, and males unknown. Thonus eroshenkoi n. comb. and T. medianus n. comb. are proposed. Thonus kaszabi and T. medianus n. comb. are new records for the Romanian nematode fauna. [ABSTRACT FROM AUTHOR]

Two known and two new species belonging to the genus Thonus, namely T. angulosus sp. n., T. circulifer, T. cylindricus and T. diversus sp. n., collected from several locations in Romania, are described. Thonus angulosus sp. n. is characterised by body 1.53-1.75 mm long, lip region cap-like (i.e., with its inner perioral area elevated) and 12.5 μm diam., odontostyle 13-16 μm long or slightly longer (ca 1.2 times) than lip region diam., neck 335-385 μm long, pharyngeal expansion ca two-fifths of total neck length, female genital system amphidelphic, uterus 1.1-1.7 body diam. long, pars refringens vaginae with two widely separated triangular pieces, vulva a post-equatorial (V = 54-60) longitudinal slit, glands present near the vagina-vulva junction, female tail rounded to convex conoid (30-35 μm, c= 48-56, c′ = 0.8-1.0), and males unknown. Thonus diversus sp. n. is characterised by body 1.41-1.78 mm long in females and 1.33-1.96 mm in males, lip region offset by depression or weak constriction and 15-17.5 μm diam., odontostyle 15-17 μm long and 5.5-6.8 as long as wide, neck 350-410 μm long, pharyngeal expansion occupying 40-48% of total neck length, a ring-like structure surrounding the pharyngeal base-cardia junction, uterus 1.5-3.6 body diam. long, pars refringens vaginae with two closely arranged pieces, vulva a post-equatorial (V = 54-57) transverse slit, gland cells present near the vagina-vulva junction, tail rounded-conoid to rounded (18-23 μm, c = 68-87, c′ = 0.6-0.8 in females; 18-24 μm, c = 58-89, c′ = 0.6-0.8 in males) with abundant saccate bodies and with inner cuticle layer separated from outer layer, spicules 46.5-54 μm long and 4-7 separated ventromedian supplements. Thonus cylindricus is reported for the first time in Europe and T. circulifer is new record for the Romanian nematode fauna. Descriptions, measurements, illustrations, including SEM pictures of T. diversus sp. n. and distribution data of the species are provided. [ABSTRACT FROM AUTHOR]
