Introduction
Theinsect faunaofChinaiscategorizedinthePalearcticandOrientalbiogeo-
graphicalregionsandisoneoftherichestinspeciesdiversityinAsia.Thecerambycid
faunaofChinawasoncerevisedbyGREss1TT(1951). He listed1,895 taxaincluding
speciesandsubspecies. Recently in2002, HuApublisheda“List ofChinese Insects,
Vol. II” inwhichherecordedthetaxaknownupto t990. Accordingtothislist, the
number of speciesand subspecies of theCerambycidae (including Disteniidae) in-
creasedto2,643inthese40years. 0ntheotherhand,JIANGandCHEN(2001)men-
tioned in their revisionalstudyoftheChineseLepturinaeas follows: “一dueto the
