Two new species of the Catantopidae(Orthoptra:Acridoidea,)from Taiwan,China

记述了中国台湾斑腿蝗科二新种:尼蝗属Niitakacris Tinkham,1936的嘉义尼蝗Niitakacris chieiensis sp.nov.和幽蝗属OgneviaIkonnikov,1911的台湾幽蝗Ognevia taiwanensis sp.nov..前者同红胫尼蝗N.rosaceanum(Shiraki,1910)近似,不同之处为产卵瓣在基部明显加宽和下生殖板在中部加宽.后者同塞吉幽蝗O.sergii Ikonnikov,1911近似,其区别特征为:前胸背板沿中隆线缺黑色纵纹,沟后区长于沟前区;中胸腹板中隔较狭,最小宽度等于长度;上产卵瓣的基部2/3的上、下缘近平行;下生殖板基部微狭.

Two new species of the Catantopidae from Taiwan,China are described in this paper.Niitakacris chieiensis sp.nov.is similar to N.rosaceanum(Shiraki,1910),but differs from latter by the ovipositor valves wider distinctly at base and subgenital plate widened in the middle.Ognevia taiwanensis sp.nov.is similar to O.sergii Ikonnikov,1911,but differs from the latter by pronotum without black stripe along median keel,metazona longer than prozona;interspace of mesosternum narrower,minimum width equal length;2/3basal part of upper ovipositor valve near parallel in upper and lower sides;subgenital plate slightly narrower in basal part.
