摘要
The paper reports a new genus of Arcypteridae i e. Suacris gen.nov.and a new species Suacris siyangensis sp.nov.The new genus is similar to Omocestus I Bol ,but differs from the latter in:① Lateral carinae slightly curved,widest 1 6-1 8 times greater than narrowest.② Cubital area wider than or equal to medial area.③Tympanum organ distinct,♂ widely oval,♀ crevice like.The new genus is also similar to Stenobothroides Xu et Zheng,but differs from the later in:①Lateral carinae obvious and curve.②Tergum of terminal abdomere without furcula.③Male subgenital plate long conica.Type specimens are deposited in Northwest Plateau Institute of Biology,the Chinese Academy of Sciences.
记述了采自江苏泗阳县网翅蝗科 1新属———苏蝗属Suacrisgen .nov 及 1新种———Suacrissiyan gensissp .nov 。该新属近似于牧草蝗属OmocestusI Bol ,其主要区别特征为 :前胸背板侧隆线微微弯曲 ,最宽处为最窄处的 1 6～ 1 8倍 ;前翅肘脉域几乎等宽或略宽于中脉域 ;鼓膜器雄性宽卵形、雌性狭缝状。该新属也近似于拟草地蝗属StenobothroidesXuetZheng ,其主要区别特征为 :侧隆线明显且弯曲 ;雄性腹部末节无尾片 ;雄性下生殖板长锥形。新种模式标本保存于中国科学院西北高原生物研究所。1 苏蝗属 ,新属Suacrisgen .nov模式种 :泗阳苏蝗Suacrissiyangensissp .nov .正模 :1♂ ;副模 :1♀ ,江苏泗阳 ,195 7 Ⅸ 16 ,采集者未知。体小型。头大而短 ,较短于前胸背板。头侧窝明显 ,呈长方形。颜面向后倾斜。中单眼较小于侧单眼。触角丝状 ,基部触角节宽大于长 ,向端部触角节渐渐变狭。前胸背板中隆线明显 ,侧隆线在沟前区微微弯曲 ,其最宽处约为最窄处的 1 6～ 1 8倍 ;前胸背板后缘中央钝角形。前、后翅发达 ,超过后股节中部 ,前翅顶端圆形 ,无凹陷 ,前翅肘脉域几乎等宽或略宽于中脉域。中、后胸腹板侧叶全长均明显地分开。后足股节内侧具发音齿 ,可与前翅纵脉磨擦发音。后足胫节缺外端刺。鼓膜器 :雄性宽?
