Among them two new species belong to Phyllomegacopta Ren, gen. nov., other one new species belong to Megacopta Hsiao et Jen, also including one new synonym (Coptosoma lunata Ren = Coptosoma lasciva Bergroth), one combination is suggested (Phyllomegacopta majuscula Hsiao et Jen, comb. nov.) and provide detailed illustrations for above species { including Megacopta cribraria (Fabricius)} (Figs.1-42) . Measuments are given millimeters. The type specimens are deposited in the Department of Biology, Nankai University. The new genus and new species are here briefly diagnosed.Phyllomegacopta Ren, gen. nov. This genus is close to Megacopta Hsiao et Jen in body appearance, above with coarse punctures and feature of legs, but head shape, sublateral area of ventrite marked, genitiala outline and structure conspicuous different, particul conjunctical lobes of aedeagus with strongly sclerotized region at apices; base of paramere stem-like, middle area wider and slightly twisted, tipe obscure. The new genus conspicuous differ from type species Megacopta cribraria (Fabricius) (figs. 1-5) of Megacopta Hsiao et Jen . Type species: Megacopta majuscula Hsiao et Jen Phyllomegacopta cobbeni Ren, sp. nov. (figs. 6-15) Body fuscous, with yellow making. Central lobe of head uniformly dark riddish brown, shining and convex; vertexal base and inner area of eyes, black; lateral lobes yellow, bearing sparse fuscous punctate; puncturing of scutellum shagreening stronger. Peritreme of mtathoracic scent-gland with yellow-brown at apex. Legs yellow-brownish, femora with fuscous points. Abdomen black, shining at disk, with transversely punctate; half-ring shape yellow spot at sub-lateral margins region. Male body length 5.6, width 5.4. Head length 1.1, width 1.8. Length of antennal segments I: II: III: IV = 0.35: 0.58; 0.44: 0.50. Length of pronotum 1.8, width of between lateral angles 4.4; wi
