Aquatic oligochaete plays an important role in freshwater ecosystem. These worms, therefore, have already been extensively studied around the world. But compared to other countries with East Asia, only 48 species of aquatic oligochaetes have been recorded in Korea. This is because taxonomic study of aquatic oligochaete is in just beginning stages. Our specimens of this study had been collected from eighteen locations in Korean peninsula. Analyzing them we identified twenty unrecorded species including one species of aelosomatid: Paranais orientalis, Pristina breviseta, P. notopora, P. foreli, P. synclites, Bratislavia prosetosa, Allonais gwaliorensis, Aulodrilus pluriseta, Limnodrilus neotropicus, L. maumeensis, L. amblysetus, Tubifex ignotus, Potamothrix cf. bedoti, P. bavaricus, Peipsidrilus cf. pusillus, Psammoryctides albicola, Varichaetadrilus vestibulatus, Tasserkidrilus cf. acapillatus, Propappus volki, Aeolosoma japonicum.

The infection by Limnodrilus hoffmeisteri $Clapar{\grave{e}}de$, 1862 (Oligochaeta: Tubificinae) in humans is relatively uncommon. The present report is to describe an incidental human infection with oligochaetes in the nasal cavity of a Chinese man, a 25-year-old man residing in Zhangjiakou city, Hebei province, China presenting with nose bleed, severe itching, continuous sneezing, and rhinorrhea. A lot of oligochaete worms were found in the nasal discharge of the patient. The detected worms were identified as Limnodrilus hoffmeisteri (Annelida: Oligochaeta) based on morphological and molecular characteristics. This incidental L. hoffmeisteri nasal infection is the first case in China and indicates that oligochaete worms can be encountered in humans.
