Abstract

Three species of the genus Nygolaimus - N. brachyuris(De Man, 1880) Thorne, 1930, N. obtusus Thorne, 1930, and N. parvus Thorne, 1974 - are newly recorded in Korea. These three species are distinguished from their congeners by the following characteristics: short tail, wider body, and weak mural tooth in N. brachyuris; wider lip region, long tail, and long body in N. obtusus; all characteristics(such as body, pharynx, and tail length) are generally smaller in N. parvus. All specimens were collected from freshwater and sediment in Han River. In this study, detailed descriptions and morphometric values of these three species are provided. Additionally, DNA barcode sequence information from the 18S rDNA gene is also provided for molecular species identification.
