Abstract
The genus Dorylaimoides Thorne and Swanger, 1936 comprises over 70 species and predominantly inhabits soil; however, some species are found in semiaquatic or aquatic habitats. In this study, D. elegans(de Man, 1880) Thorne and Swanger, 1936 and D. limnophilus (de Man, 1880) Loof, 1964, collected from sediments in the Hangang River, are reported for the first time in Korea. These two Dorylaimoides species are distinguished from other Dorylaimoides species by their morphological characteristics: a didelphic-amphidelphic reproductive system, short tail, and digitate terminus in D. elegans and a mono-opisthodelphic reproductive system and long tail in D. limnophilus. Here, we provide detailed information on the morphological characteristic (description and illustration) and morphometrics of the two Dorylaimoides species, using optical microscopy. Additionally, 18S rDNA sequences of the two species from the Korean isolates are provided as molecular evidence.
