The family Sisyridae is very unique in that their larvae are aquatic and feed on sponges. The family has not been described in Korea until one species, Sisyra nikkoana (Navas), of Sisyridae was reported in the Illustrated Book of Aquatic Invertebrates in Agricultural Ecosystem (Rural Development Administration, 2008). However, this short description includes a misidentified adult image, and here we provide its full description in morphology with its wing pattern and male genitalia, as well as its COI barcoding information. We suggest its Korean name, 해면풀잠자리(해면풀잠자리과) as they feed on sponges.
