New species Drepanidotaenia czaplinskii sp. n. from Netta rufina (Pall.) (Anatidae) is described and figured. The new species differs from the type species of the genus, D. lanceolata, by longer rostellar hooks (0.055-0.060 in D. czaplinskii vs. 0.030-0.037 in D. lanceolata) and a relatively shorter hook blade, in cirrus size and shape, in cirrus sac size and length of vagina. The narrow interpretation of generic diagnosis of Drepanidotaenia (Spassky and Spasskaya 1954) is supported and only two valid species (D. lanceolata, D. czaplinskii) are recognized in this genus.
