This new genus is rather similar to Hemeroscopus Pritykina,1977, but differs from the latter in the following characters:(1) hindwing anal loop is smaller, only with 6-7 cells;(2) Rspl is absent;(3) the hindwing vein CuAa is curved and has five distinct posterior branches;(4) the forewing MP is not shortened, reaching the posterior wing margin slightly beyond the level of the nodus;(5) pterostigmata more distinctly braced;(6) the hindwing area between MP and CuAa is narrow, with only one row of cells near the discoidal triangle.
新属与巴依萨昼蜓HemeroscopusPritykina，1977在形态上比较相似，但在演化程度上更为原始，主要体现在下面几个方面：(1)后翅臀套较小，仅有 6～ 7个翅室；(2 )径增脉缺；(3)后翅CuAa脉弯曲，带有 5个明显的后分支；(4 )前翅MP脉不显短，终止于翅后缘近翅结处；(5 )翅痣下有一个明显的支脉；(6 )后翅CuAa和MP域基部较窄，在三角室下方仅有 1排翅室。

Length 9mm, exhibition wing 20mm; body was pale green; first sudden cone, into the front, so called as Fulgoroidea; wings transparent, wings light brown mole.
体长9mm，翅展20mm；身体呈淡绿色；头突锥状，伸向前方，故称之为象蜡蝉；翅透明，翅痣淡褐色。

Firstly, the high resolution pictures of dragonfly wings from sample tests were studied thoroughly, and the unique feature of the reticulate vein distribution and the variation of the vein sizes and the grid shapes in different zones were figured out;then several computational models based on a dragonfly wing were established by using ANSYS, and beam 189 and shell 93 elements were used respectively in modeling of the veins and the membrane so as to ensure the compatibility between the veins and the membrane at a deformed state;these models subject to uniform loading cases were analyzed respectively so as to explore the unique performances of the wing structure, furthermore, through eigenvalue spectrum analyses of these models, the special role of the pterostigma in eliminating or suppressing the wing quivering effect was also evaluated.
首先，对实验中获取的高清晰度的蜻蜓翅膀数码图片进行了细致地分析，找出了翅膀网状翅脉结构中翅脉的分布规律与尺寸变化、网格形状的差异及不同形状网格的分布等独特的结构特征；再利用ANSYS建立蜻蜒翅膀网状翅脉结构模型，采用三节点等参数梁元beam189模拟翅脉和八节点等参数曲壳单元shell93模拟翅膜，以满足翅脉和翅膜间的变形协调性要求；通过非线性数值分析，探索了蜻蜓翅膀网状翅脉结构在均布荷载作用下所具有的独特的结构性能；通过模态分析，揭示了翅膀前缘靠近翼尖附近的翅痣在翅膀消震减振中所发挥的作用。
