摘要
记述了采自新疆的拟槌角蝗 Gomphoceroides 新属及新疆拟槌角蝗Gomphoceroides xingangensis 新种.该新属近似于 Gomphocerippus Rob.和Gomphocerus Thunberg.其区别于两者为前胸背板后横沟雄性在背板中部穿过,雌性在中后部穿过;前翅前缘基部在雌性明显扩大,雄性不明显;缘前脉域端部明显超过前翅中部.其区别于前者为前翅前、后肘脉接近、合并;中脉域宽为肘脉域5～6倍.而区别于后者为雄性前足胫节不膨大.
A new genus and a new species of grasshopper from Xingjiang are reported.The type specimens are deposited in the Institute ofZoolgy,Shaanxi Normal University. Gomphoceroieds gen.nov. Of medium small size.Head is shorter than pronotum.Vertex,short and wide, fastigium of vertex with right angle.Foveolae,quadrilateral.Frons,slightly obliqre.Antennae clavate,longer than head and pronotum together.Eyes,small, oval.Pronotum with curved lateral keels;in male,the posterior transverse sulcus situated in the middle of pronotum;and in female,in the hind part of pronotum;hind margin obtusangular.Metasternal lobes separate on their whole length.Elytra,developed;the base of protoloma distinctly expand in female,indistinctly in male;the tip of precosta area distinctly reaches beyond half of the elytron;the two cubital veins are closed to each other,merged;width of media area about 5～6 times larger than cubital area.Anterior tibiae normal,not expanded.Genicular lobes of hind femora rounded,Inner spurs of hind tibiae,well developed,the length of lower spur is longer than upper spur(about 1.25 times).Tympanum well developed. Type species:Gomphoceroides xingjiangensis sp.nov. This new genus is allied to Gomphocerippus Rob.and Gornphocerus Thunb.It differs from the both in:1)the posterior transverse sulcus of male is situated in the middle of pronotum,and in female,in the hind part of pronotum;2)the base of the protoloma distinctly expands in female,indistinctly in male;3)the tip of precosta area is longer than half of the elytron.It differs from the former by the two cubital veins closed to each other,merged;width of media area is about 5～6 times alrger than cubital area It differs from latter by anterior tibiae normal. Gom phoceroides xingjangensissp.nov.(figs.1-12) Length of body:17～18mm;19.5～21mm. Lenght of pronotum:2.8～3mm;3.8～4.2mm. Length of elytra:11～12mm;12～13mm. Length ofhind femur:9.5～10mm;11～12mm.
