Remarks. In the genus Taphrocampa Gosse, 1851 , only three valid species are recognized, T. clavigera Stokes, 1896 , T. annulosa Gosse, 1851 , and T. selenura Gosse, 1887 . Taphrocampa species are easily recognized by their oblique corona with auricles and vermiform bodies which are stretchable and plicated like an accordion. The present study is the first report on the species as well as the genus Taphrocampa from Korea. In Asia, this species has previously been reported from Cambodia ( Meas and Sor, 2014), India ( Segers et al., 1994), Japan ( Sudzuki, 1975) and Laos ( Segers and Sanoamuang, 2007).
