Resembling L. semipunctata (Fabricius), but its antenna black; last segment of maxillary palpus larger than second; anterior-lateral portions of metasternum not clothed with dense pubescence. Whereas in semipunctata-, its antenna reddish broun; last segment of maxillary palpus not larger than second; anterior-lateral portions, of metasternum clothed with dense pubescence.Length: 8-8.7mm; breadth: 3.3-3.5mm.Holotype(?), 800m, July 26, 1984, LongJianguo; allotype (?), 800-1000 m, February 27, 1982, Long Yongcheng; paratype 1(?), 600m, July 7, 1981, Chen Jiadong; all from Jianfeng.Ling, SW.Hainanls.Lilioceris xinglongensis Long, sp.nov.Reddish brown; antenna, scutellum, legs, meso- and metapleura and sides of metasteraum black.Differs from L. cyaneicolHs’.(Pic) in having antenna cylindrical, only about a third as long as body; scutellar rows of punctures without punctures; apex of mcsosternum perpendicularly ,connected with metasteraum between two mesocoxae. Whereas in cyaneicollis , its antenna flattened feebly; about one half as long as body; scutellar rows of punctures with punctures; mesosternum parallelly connected with metasternum between two mesocoxae.Length: 9.7mm; breadth: 4.3mm.Holotype(?), Xinglong, S.Hainan Is., 50-150m, Sept.29-Oct.3, 1980, Xia Shiyang.更多还原
