Chironomid adults attracted to the light were collected at Dangsan-ri, Muju-eup, Muju-gun, Jeollabuk-do in 2008-2009. Two new species, Lymnophyes parakitanaides sp. nov. and Parakiefferiella mujuensis sp. nov., and four unrecorded species, Cardiolcladius capusinus, Thienemanniella vittata, Conchapelopia pallidula, and Nilotanypus dubius were found and are described with illustrations. The genera Thienemanniella and Nilotanypus have not been previously reported in Korea. The genus Thienemanniella which belongs to Orthocladiinae is characterized by the radial sector retracted and apically fused with the costa, and the genus Nilotanypus which belongs to Tanypodinae is characterized by the absence of $R_{2+3}$, pubescent eyes and lack of the gonocoxal lobes.
