| description | Two new and two known species of the genus Eudorylaimus belonging to the family Qudsianematidae are described and illustrated from Northeast China. Eudorylaimus blisterocaudatus sp. nov. is characterized by its 1.0–1.3 mm long body, lip region offset by constriction and 15–17 µm wide; odontostyle 1.0–1.2 times the lip region diameter long, odontophore 1.3–1.5 times the odontostyle length, pharyngeal expansion occupying ~ 41–47% of total neck length; V = 59–63%, uterus tripartite 1.3–3.8 times the corresponding body diameter, vulva post-equatorial, spicules 39–45 µm long, 6–8 irregularly spaced ventromedian supplements, tail conoid, sub-digitate with rounded terminus in both the sexes. Eudorylaimus saccatus sp. nov. is characterized by its 1.1–1.4 mm long body, lip region offset by constriction and 15.0–17.5 µm wide; odontostyle 1.0–1.2 times the lip region diameter long, odontophore 1.3–1.5 times the odontostyle length, pharyngeal expansion occupying ~ 44–48% of total neck length; uterus tripartite, 1.3–2.1 times the corresponding body diameter, V = 62–63.3%; tail conoid, dorsally convex, with sub-digitate terminus in both the sexes and males with 44–48 µm long spicules and 9–11 irregularly spaced ventromedian supplements. Two known species E. meridionalis and E. caudatus are reported for the first time from China and one male specimen of E. caudatus is recorded here for the first time. |
