Abstract

Four new species of Dorylaimida from Korea are described and illustrated. Belondira pugwiensis n. sp. is 1.7–1.9 mm long, b = 3.3–4.2, c = 58.1–65.8, V = 35–37, odontostyle = 6.5–7.3 μm and characterized by having a prominent spindle-shaped valve area in the anterior part of oesophagus and long expanded part of oesophagus, occupying 68–70% of total oesophageal length. Lindseyus juwangens sp. n. is 3.5–4.1 mm long, b = 13.3–14.5, c = 11.6, V = 40–40.3, odontostyle = 6.6–7.4 μm and characterized by having a slender body, short odontostyle and longer spicule. Prodorylaimus donghagens sp. n. is 1.7–2.1 mm long, b = 3.9–4.6, c = 5.8–6.3, V = 47–49, odontostyle = 29.2–32 μm and characterized by continuous, truncated lip region and ventrally hooked tail end. Prodorylaimus taebekensis sp. n. is 1.2–1.5 mm long; b = 4.2, c = 5–6, V = 43.3–47.2, odontostyle = 16–19 μm, spicule = 35–46 μm and ventromedian supplements = 5–6 and characterized with slightly set off lip region and long filiform tail with ventrally hooked terminus.
