Abstract
The genus Tripylina Brzeski, 1963 is a group of terrestrial nematodes that inhabit soil and semi-wet biomes, most of which have been reported from Europe, Asia, America, Africa, and New Zealand. Tripylina stramenti (Yeates, 1971) Tsalolikhin, 1983, belonging to the family Trischistomatidae Andrássy, 2007, is newly discovered from Korea. The specimens were collected from the edge of the valley of Ulleung-gun, Gyeongsangbuk-do, South Korea. Tripylina stramenti described herein shows typical morphological characters of the genus Tripylina, including six and four setae in a single whorl, present dorsal tooth and subventral teeth, prodelphic reproductive system of female, absence post-uterine sac, narrow sickle-shaped spicule of male and generally S-shaped tail. The specimens differ in their body width (from the New Zealand populations), outer labial setae length, cuticles thickness (from the West African populations), and nerve ring position (from Indian populations). This species is distinguished from other Tripylina species by its relatively large body, two anterior and subventral teeth, and single cervical seta. In this study, morphological characteristics and morphometric information of the Korean T. stramenti isolate are described, illustrated, and compared with the same species from other geographic origins.
