A revision of Chrysso O. Pickard-Cambridge, 1882 sensu lato is presented based on specimens collected from China. A new genus, Megama gen. nov., is established, based on Meg. decimaculata sp. nov. (male, female) from Hubei, China as the type species, with an additional species Meg. bimaculata (Yoshida, 1998), comb. nov. Two new species of Meotipa Simon, 1895, Meo. cordata sp. nov. and Meo. vittiforma sp. nov., are described, and four new combinations are proposed. The genus Physcoa Thorell, 1895, stat. rev. is revalidated, with its type species P. scintillans Thorell, 1895, comb. rev., along with seven new combinations. All the new combinations proposed in the current paper are transferred from the genus Chrysso. Diagnoses for the four genera are provided, along with diagnoses, descriptions, and photos of the new species.
