Two New Species of the Tribe Saperdini Mulsant from China (Coleoptera:Cerambycidae:Lamiinae)

Two new species of Saperdini of Lamiinae are described in this paper.All the type specimens are deposited in the Insect Collection,Southwest Agricultural University. 1 Paraglenea nigromaculata sp.nov.(Figs.1-4) Body moderate,black clothed with ocherous to sulphur yellow pubescence on most of ventral surfaces;head and antennae yellowish-brown,blackish-brown on first two segments and the apical parts of 3-11 segments of antennae except the basal portion of 3-11 segments which covered with fine gray white pubescence.Pronotum black with orange pubescence,densely.Elytral middle with a transverse black macula.Ventral surface black densely covered with yellowish-brown pubescence except last segment,yellowish-brown. Frons subquadrate,lower eye-lobe longer than broad,longer than gena in male and the same deep in female;antennae as long as body.Pronotum finely punctate,densely,a middle ridge. Male genetalia (Figs.2-4):Lateral lobes short and soft,furnished with fine setae apically;ringed part geniculated and rimed;median lobes with median structs moderately curved and the fomer equal to the latter;ventral margin of median orifice pointed.Internal sac decorated with a pair of basal armatures and uniform microtrichia inside and with two bone rods and a flagellum.With single ejaculatory duct. Length:12.5-16.5 mm;breadth:4-6 mm. Holotype ♂,Yan an (36°35′N,109°28′E),Shaanxi Province,1980,by SHUN Yi-zhi.Paratype:1♂,Daixian County (39°5′N,112°58′E),Shanxi,9-Ⅴ-1987;2♀♀,Datai,Huhehaote (40°52′N,111°39′E),Neimeng,21-Ⅵ-1964,by LIU Xin-hua. Distinguished from its congeners by the colour of elytra and elytral maculations and from Paraglenea fortunei (Saunders)by male genitalia in the following characters:basal armatures 2 pairs instead of 3 piece and 2 bone rods in apex short istead of slender,etc. 2 Glenea nigromarginella sp.nov.(Figs.5-8) Body moderate and ochraeous;black in vertex,occiput,antennae and eyes;sides of pronotum,elytral lateral margins,abdomen,external of femora and tibiae,tarsi,apex of hind femora and hind tibiae;ochraeous in others of dorsal surface. Frons densely clothed with yellowishbrown pubescence and decorated with black erect setae,pronotal disc densely covered with ochraeous pubescence and margins of pronotum with golden pubescence.Scutellum entirely clothed with golden pubescence.Elytron covered with ochraeous pubescence and with black setae in base;ventral surface densely clothed with golden pubescence.Antennae slightly longer than body,scape cylindrial,shorter than the 3rd and longer than the 4th,the basal four segments densely bearied cilia on beneath.Pronotum puctured,densely punctured in elytra. Mele genitalia (Figs.6-8):Laterallobes short,oblique at apex with little setae.Median lobe with median structs narrowed at base and broaden at apex.Median lobe shorter than median structs;ventral margin of median orifice produced.Internal sac large with basal amatures and two bone rods;with single ejaculatory duct. Length:14.5 mm;breadth:4.5 mm. Holotype ♂,Longzhou(22°21′N,106°53′E),Guangxi Province,30-Ⅴ-1997,by YANG Mao-fa. Distinguished from its congeners by the colour of body,pronotal sides and elytral margins,external margins of legs,apex of hind femora and hindtibiae.Differ from Glenea cantor (Fabricius) by male genitalia in the follows:ventral margin of median orifice projected instead of pointed and basal armatures 2 pairs,1 stound and short,the other slender,etc.
