摘　　要：A new dragonfly of family Meganeuridae Shenzhousia qilianshanensis gen. et sp. nov., discovered from Ningxia Hui Autonomous Region in North China, is described in the present paper, it has an estimated wingspan of about 450-500 mm and may be the largest fossil insect in Late Carboniferous Namurian Stage discovered by far. The new species is referred to Meganeuridae because of the presence of the characteristic oblique vein between anterior branch of radius （RA） and posterior branch of radius （RP） near the base of RP2. It differs from other genera within the family in the following characteristics： Precostal area short and not extending to the midwing; posterior branch of subcostal vein short, merging into costal vein near the level of originating point of IR2; RP forking earlier than anterior branch of media basally; RP（1 ＋ 2） and RP（3 ＋ 4） parallel and close to each other for a long distance, and then diverge gradually surpass midwing.家庭 Meganeuridae Shenzhousia qilianshanensisge 的一只新蜻蜓。et sp。nov，在诺思中国从 Ningxia Hui 自治区域发现了，在现在的纸被描述。它有大约 450-500 公里的估计的翼展并且可以是在迄今为止发现的晚含碳的 Namurian 舞台的最大的石块昆虫。新种类是因为在半径(RA ) 的前面的分支和半径(RP ) 的以后的分支之间的典型倾斜的静脉的存在，在 RP <SUB>2</SUB> 的底附近指了 Meganeuridae。它在下列特征在家庭以内不同于另外的类：对中间的翅膀短、不扩大的 Precostal 区域；以后的分支突然代替肋骨的静脉，在红外 <SUB>2</SUB> 的发源的点的水平附近合并进肋骨的静脉；基础地比媒介的前面的分支早分叉的 RP；RP <SUB>1+2</SUB> 和 RP <SUB>3+4</SUB> 平行和为长距离的结束到对方，然后逐渐地分叉超过中间的翅膀。
