  • The genus Prionchulus Cobb, 1916 represents a group of predaceous nematodes belonging to the family Mononchidae Chitwood, 1937, and is found worldwide. However, only five species have been reported thus far from Korea. Prionchulus oleksandri Winiszewska and Susulovsky, 2003 is reported for the first time from Korea, from sediments collected from the Nakdong River. This species is distinguished from other Prionchulus species by its truncated lip region with small cephalic papillae and refringens vaginae. In this study, morphological characters(detailed morphometrics) of P. oleksandri are described and illustrated using optical microscopy. DNA barcode sequence information (the D2-D3 region of 28S rDNA, 18S rDNA, and internal transcribed spacer rDNA) is also provided for the molecular identification of the species.

  • Mylonchulus jinjuensis n. sp. is 1.8-2.2 mm long, spicules 58-$67{\mu}textrm{m}$ long and is distinguishable by basally situated subventral teeth, presence of hypodermal glands and ventural body pores. Mylonchulus taeguensis n. sp. is 1.3-1.8 mm long, spicules 52-$64{\mu}textrm{m}$ long and is characterized by having small denticle on dorsal wall of buccal cavity at the level of dorsal tooth apex, and two each pre- and post-vulval papillae. Mylonchulus polynicus is reported here for the first time from Korea, is described and illustrated. Princhulus pachydermis n. sp. is 2-2.3 mm long and is distinctive in having very thick body cuticle and absence of caudal glands and spinneret. Prionchulus koriensis n. sp. is 1.7-2.0 mm long and is characterized by having elongate-conoid tail with sharply pointed terminus and presence of caudal glands.
