Abstract:
Three new genera (Noldo gen. n., Yavanna gen. n. and Nienna gen. n.) of the family Acerellidae Yin, 1983, and ten new species (Hesperentomon martynovae sp. n., Proturentomon stebaevae sp. n., Filientomon sibiricum sp. n., Verrucoentomon aurifer sp. n., V. joannis sр. n., Noldo submontanus sp. n., Yavanna altaica sp. n., Nienna parvula sp. n., Imadateiella murka sp. n. and Eosentomon tshergense sp n.) are described. The porotaxy (the distribution of the glandular pores) is introduced as taxonomically important character in Acerentornoidea. The key to the genera of the subfamilly Acerellinae (fam. Acerellidae) is provided.
