Here we describe and illustrate a new genus and species of the extinct froghopper family Sinoalidae, Cretomultinervis burmensis gen. et sp. nov. from Burmese (Myanmar) amber. The new genus can be recognized from all sinoalids by the combination of an enlarged pronotum, hind tibia armed with five interlaced lateral spines, leaf-shaped tegmen with very broad postcostal cell, basal cell extremely long, hindwing with costal margin armed with 5 micro-spines basally, and cross vein mp-cua apparently basad of stem CuA fork. This peculiar combination of primitive and derived characters suggests that Cretomultinervis likely represents an early-diverging lineage of Sinoalidae, increasing our knowledge on the morphological disparity of this extinct family during the late Mesozoic.

在这里，我们描述并说明了已灭绝的蛙蝉家族中华al科的新属和种，即Cretomultinervis burmensis属。等 十一月 来自缅甸（缅甸）的琥珀色。新的属可以通过以下方法从所有鼻窦中识别：扩大的前胸背板，后胫骨，五个交织的侧棘，叶状筋骨，后肋细胞非常宽，基底细胞非常长，后缘，肋前缘和5 micro-基底棘刺，并且茎CuA叉的横脉mp-cua显然是基底。这种原始字符和派生字符的特殊组合表明Cretomultinervis 可能代表中华Sino科的早期分化谱系，这增加了我们对中生代晚期该灭绝科的形态差异的认识。
