Abstract The extinct froghopper family Sinoalidae is the most diverse amongst the infraorder Cicadomorpha at generic level in the mid-Cretaceous amber of northern Myanmar. Here we describe and illustrate a new species of Sinoalidae, Jiaotouia burmitica sp. nov. from Burmese amber, representing the second species of Jiaotouia Chen and Wang, 2019, adding new information on morphological diversity of this genus. The new taxon can be distinguished from the type species by its narrowed anteclypeus, antenna with flagellomere 1 and apical tarsomere of metatarsus elongate, tegmen in having the cross vein mp-cua well-developed rather than replaced with anastomosis. Jiaotouia is emended and provided detailed morphological characters of J. minuta on the basis of two well-persevered specimens from Burmese amber, and the intra-specific variation of J. minuta is discussed.

对角头亚属（半翅目、尾蜂总科）的修订以及对中白垩世缅甸琥珀新种的描述

摘要 在缅甸北部中白垩世琥珀中，已灭绝的蛙蛙科是Cicadomorpha 亚目中种类最多的一类。在这里，我们描述和说明了中华鳖科的一个新种，焦头亚 burmitica sp。十一月 来自缅甸琥珀，代表了 Jiaotouia Chen 和 Wang 的第二个物种，2019，增加了关于该属形态多样性的新信息。新分类群可以通过其狭窄的前缘、带有鞭毛1的触角和跖​​骨的顶端跗骨细长、具有发育良好的交叉静脉mp-cua而不是被吻合术取代的tegmen而与模式种区分开来。以两个保存良好的缅甸琥珀标本为基础，对角头亚进行了修正，并提供了细头龙舌兰的详细形态特征，并结合了缅甸琥珀的种内变异。
