Abstract. Reticycla drosopoulosi gen. et sp.n. from the Early Cretaceous of Khasurty, Buryatia is described in Hylicellidae Vietocyclinae (Cicadomorpha). The genus Jiphara Ren, 1995 from the Early Cretaceous of China is transferred from Pereboriidae to Vietocyclinae. Stigmapsylla klimaszewskii gen. et sp.n., Liadopsylla (Basicella) lautereri subgen. et sp.n. and L. (B.) loginovae sp.n. from Khasurty are described in Liadopsyllidae s. str. (Psyllomorpha). Free CuA base and nodal line are first reported in forewings of Mesozoic Psylloidea. Two species from Cretaceous ambers are transferred from Liadopsylla to Cretapsylla gen.n.: C. apedetica (Ouvrard, Burckhardt et Azar, 2010) comb.n., C. hesperia (Ouvrard et Burckhardt, 2010) comb.n. The family Malmopsyllidae is resurrected from synonymy with Liadopsyllidae and divided into Malmopsyllinae, stat.n. and Miralinae subfam.n. (for Mirala Burckhardt et Poinar, 2020 from Burmese amber). The insect assemblage and other fossil finds from Khasurty as well as the age and paleoenvironment of this fauna are briefly discussed.
