Pronotum length slightly shorter than width, posterior angles bluntly rounded, disc convex, without depression on medio-lateral sides, smooth and without wrinkles and punctures, shallow and fine punctures being visible under higher magnifications. Scutellum triangular, smooth and impunctate. Elytral base wider than pronotum; punctures shallow and fine, weaked backward. Male fore-tarsomere 1 not broadened. Hind femur is not as thickened as other species of the genus, but with spring organ. Last sternite of abdomen depressed medially, spoon-shaped（Fig.26）, apex tri-lobed. Aedeagus robust and short, apex wide （Fig. 11）. Body length： 3mm. Holotype ♂, China, Sichuan, Ganzi, Meiren Valley, 2240-2500m, 2 Aug. 2004, leg. BAI Ming. Paratypes： 180♂♂♀♀, ditto, leg. BAI Ming, WAN Xia, ZHANG Yong, XUE Huai-Jun. Remarks. The new species has some similarity with L. antennata Chen from Sichuan province, but L. antennata with antennamere 4-7 strongly serrated, last sternite of abdomen with a large round depression（Fig.25）. Etymology. The new species is name from the tutor of first author, Prof. CHEN Sicien for the memory of his great contribution on the systematic on Chrysomelidae and his carefully instruction on the first author. 2 Luperomorpha glabricollis Wang et Ge, sp. nov. Descriptions. Head, pronotum and fore-leg yellowish brownish, eytra black with a yellowish white rounded marking on the disc（Fig. 24）, meso- and metasternite, abdominal sternite totally black, fore- and mid-legs yellowish brown, hind-femur reddish black, tibiae and tarsi of each leg infuscate; antennae black except basal three segments yellowish brown. Vertex smooth and impunctate, frontal tubercles subtriangular, anterior angles extending to between antennal socket, distinctly divided from each other with short longtitudinal furrow; clypeus rather prominent, subtriangular. Antennae robust, exceeding to anterior part of elytron marking, second and third segments short, subspheral, third slender either, forth longer than length of second and third combined, each remainder segment slightly shorter than forth, cylindrical, subequal with one another, length about two times as long as apical width. Pronotum shining, smooth, impunctate and without depression, very fine punctures being visible under higher magnifications, anterior angles prominent, posterior angles rounded. Scutellum narrow triangular, smooth and impunctate. Elytra slender, base with dense and fine punctures, then shallower backwards. Male fore- and mid-tarsomere 1 slender, last sternite of abdomen obviously tri-lobed, with triangular depressions medianly. Aedeagus curved on lateral view （Fig. 15）. Body length： 3.0mm. Holotype ♂, China, Guangxi, Jinxiu, longwangzhuang, 600m, 20 May 1999, leg. GAO Yuan-Ming. Paratypes： 2♂♂, China, Guangxi, Tianlin, 1300m, 2 June 2002, leg. JIANG Guo-Fang; 1♂, Guanxi, Fangcheng, Fulong, 240m, 14 March 1998, leg. ZHU Chao-Dong. Remarks. The new species is closed to L. sasajii Kimoto from Taiwan, but the new species with meso- and metasternite, and abdomen entirely black, pronotum smooth and impunctate, aedeagus of male genetalia curved; L. sasajii with meso- and metasternite, and abdomen dark brown, pronotum with fine punctures. Etymology. From Latin, ＂glabr＂ means smooth, ＂coll＂ means neck, ＂galbricollis＂ means pronotum smooth. 3 Luperomorpha guangxiana Wang et Ge, sp. nov. Descriptions. Head, prothorax, fore- and mid legs reddish brown,scutellum and elytra black, some specimens being brownish black, underside brownish black, hind-legs dark brown, antennae black except basal three segments reddish brown. Vertex convex and shining, posterior margin of frontal tubercles with some fine and shallow punctures, frontal tubercles catty-cornered, subtriangular, anterior part extending to between antennal socket, distinctly divided from each other with short longtitudinal furrow; inter-antennal space rather prominent, forming subtriangular convex together with clypeus. Antennae robust and longer, exceeding to middle part of elytra, first narrow basally, then widened apically, second and third spheral, second as wide as first apically, third shorter and narrow, forth longer than length of second and third combined, remainder slight short, forth to seventh segments triangular, slightly serrated, apical four segment filiform, each length 2 times as its apical width （Fig. 5）. Pronotum convex, smooth, impunctate, and without depression, shallow and fine punctures being visible under higher magnifications. Scutellum triangular, smooth and impunctate.Elytra slightly short and broanded, with dense and coarse punctures. Male fore-tarsomere 1 not broadened. Last sternite of abdomen tri-lobed, depressed medianly. Aedeagus curved, C-shaped on lateral view, depressed apically on ventral view, apex with a notch medially （Fig. 19）. Body length： 2.5mm. Holotype ♂, China, Guangxi, Lingui, Wantian, 260m, 30 June 1963, leg. WANG Shu-Yong. Paratypes： 7♂♂, 6♀♀, ditto. Remarks. The new species is similar to L. nobilis Weise, but the new species with forth to seventh segments of antennae slightly serrated, punctures of elytra danser and coarser than the new species; L. nobilis with forth to seventh segments of antennae not serrated, punctures of elytra fine and sparse. Etymology. The new species is named from the locality Guangxi Province where the new species were collected. 4 Luperomorpha hainana Wang et Ge, sp. nov Descriptions.
