In this paper,a new genus and seven new species of Tetrigoidea from the southern part of Guangxi are described.Type specimens are preserved in the Institute of Zoology,Shaanxi Normal University. 1.Zhengitettix transpicula sp.nov.(Figs.1-4) This new species is allied to Zhengitettix hainanensis Liang,but differs in:① width of sulcus of frontal ridge as wide as the width of antenna basal segment;②ocelli placed the middle of anterior margin of eyes;③antennae situated between the inferior margin of eyes;④posterior angles of lateral lobes of pronotum thorn shape,long and transverse;⑤hind wing nearly reaching the top of hind tibia;⑥body ochraeus red,with many yellowish spots;⑦abdominal sterna black. ♀ length of body 8?mm,length of pronotum 11?mm,length of hind femur 6?mm. Holotype ♀,Fengcheng (Fulong),Guangxi,108°2′E,22°N,200-370?m,2-Ⅻ-2001,coll.JIANG Guo-fang. 2.Miriatroides gen.nov. Body size small.Head not elevated above the pronotum surface;vertex square,considerably protuberance before the eyes,anterior margin flat,lateral margins straight and parallel,midkeel distinct and slightly protruding before anterior margin,width of vertex as wide as the width of an eye;frons oblique,in profile with vertex forming an acute angle and protruding forward;longitudinal sulcus of frontal ridge very narrow,its width only half the width of antenna basal segment;antenna filiform,situated the lower one third of the anterior margin of eyes.Anterior margin of pronotum straight,hind process conical,slightly reaching beyond the top of hind femur;tip of posterior angles of lobes of pronotum truncate,hind margin with two concavities.Hind wing reaching the top of hind process.First segment of posterior tarsi equal to the third.Ovipositor long and narrow,upper and lower margins of upper valve parallel,its length 3.3 times the length of its width. Type species:Miriatroides quadrivertex sp.nov. This new genus is related to Rhopalotettix Hancock and Miriatra Bolivar,it differs from both by:①vertex square;②middle keel slightly projecting before anterior margin;③width of interocular distance as wide as the width of an eye;④antennae situated the lower one third of the anterior margin of eyes. 3.Miriatroides quadrivertex sp.nov.(Figs.5-8) ♀ length of body 9-10.5?mm,length of pronotum 8-10?mm,length of hind femur 6-6.5?mm. Holotype ♀,Fengcheng (Fulong),Guangxi,108°2′E,22°N,350-400?m,24-Ⅷ-1998;paratypes,2♀,Shangsi,Guangxi,108°1′E,22°N,21-Ⅷ-1998,coll.JIANG Guo-fang. 4.Hyboella longinota sp.nov.(Figs.9-11) This new species is allied to Hyboella angulifrons Hancock,but differs in :①width of vertex 1.6 times the width of an eye;②in profile,vertex and frons forming obtuse rounded;③lateral keels in prozona long,nearly parallel;④hind wing reaching beyond the top of hind femur;⑤width of midfemur wider than the width of anterior femur. ♀ length of body 12?mm,length of pronotum 14?mm,length of hind femur 4?mm. Holotype ♀,Duan,Guangxi,108°1′E,24°1′N,350?m,12-Ⅶ-1999,coll.LIU Gan. 5.Hedotettix bivalvatus sp.nov.(Figs.12-14) This new species is related to Hedotettix grossus Hancock and Hedotettix gracillis (De Haan).It differs from both in:①width of vertex narrower than the width of an eye about 1.5 times;②lateral keels of prozona constrict backward;③hind wing reaching the top of hind femur;④width of midfemur as wide as the width of elytra;⑤hind margin of subgenital plate of female two valves.It differs from the former by the disc of pronotum flat,and differs from the latter by the width of sulcus of frontal ridge as wide as the width of antenna coxa. ♀ length of body 10?mm,length of pronotum 12.2?mm,length of hind femur 6?mm;♂ length of body 9?mm,length of pronotum 12?mm,length of hind femur 6?mm. Holotype ♀,Fengcheng (Fulong),Guangxi,108°2′E,22°N,115?m,23-Ⅷ-1998,coll.JIANG Guo-fang;paratype,1♂,same as holotype. 6.Coptotettix fengchengensis sp.nov.(Figs.15-17) This new species is allied to Coptotettix conspersus Hancock,but differs in:①dorsal view,vertex protuberance before the eyes;②midkeel o
