Description
Body curved into C shape when dead. Cuticle 2.5 jum (2.5 -3.2 lim) at odontostyle level and at mid-body, 5.7 f-tm (5-7. 5) on tail; cuticle with very fine transverse striae, especially on extremities. Lateral chords 1/4 to 1 /5 body width. Lip region 14 lAmwidth (12-14 offset by a slight depression; one third the width of the body at the base of the oesophagus. Amphids stirrup-shaped about half as wide as lip region (6¡. tm). Guiding ring "double". Odontostyle length 19.5 tkm (19-22.5 [cm), one and a half times the width of the lip region; odontostyle 1.2 ttm wide (1. 2- 1. 7Am), straight, the aperture occupying one eighth the length of the odontostyle. Odontophore one and half times the odontostyle length, 29.5,um (27-31 pan) long, not flanged. Oesophagus widens at 56 Jlo of neck length from head end, the posterior part half as wide as body. The distance DO-DN is 12.5 (8-18 tkm). Locations: DO = 33-39%, DN = 58-64%, SiN = 76-82%, S2N = 83-92%, S20 = 84-92%. Cardia bluntly conoid, 15 /?m long (1 0- 1 5ttm). Nerve ring at 112.5 (112. 5-117.5 Am) from head end.
Female: Reproductive system paired, opposed, one third reflexed. Vulva transverse, vagina one-half of corresponding body width deep, with strong sclerotization. Spermatheca very well developed; a marked constriction between oviduct and spermatheca. Sperm present in the uteri. Tail 0.6 anal body diameter long, bluntly conoid to hemispherical; 30 (7-30) "saccate bodies" on tail. Rectum one, prerectum 3.5 (2.5-3.5) anal body diameters.
Male: Spicules 56 long, stout; lateral guiding pieces long. Besides the adanal pair there are eight ventromedian supplements, the posterior one at the proximal end of spicules, at from the anus. Supplements well spaced, 15-19 the first two more widely spaced: respectively 30 Ium and 20 Jim one from the other. Tail 0.7 times the anal body diameter; with 7 "saccate bodies".
Type specimens: Holotype female, allotype male, two paratype females deposited on the same slide in " Grigore Antipa " Museum Collection, Bucharest, Romania; other paratypes with the author.
Type habitat and locality: Peat bog of Lucina natural reservation, Suceava District, North Moldavia, May 1972.
Differential diagno.ri.r: Enchodelus lucinensis n. sp. comes closest to E. hopedoru. r (Thorne, 1929) Thorne, 1939, from which it differs by a more slender body, a shorter tail, a different number of supplements and vulva position; a shorter odontostyle with a longer aperture (1/ 10 in E. hopedorus); tail shorter than anal body diameter. The new species differs also from E. laevi.r Thorne, 1939 in having a more slender body and a shorter tail, a longer odontostyle (only one lip region in E. laevis), with a shorter aperture (1/4 odontostyle length in E. laevis). From E..rignyen. ri.r Loof, 1975 the new species is separated by a longer odontostyle, shorter aperture, tail, and the presence of vaginal sclerotization. By the form of the lip region (not angular) and fewer "saccate bodies" on tail, the new species can be distinguished from E. teres Thorne, 1939.
