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.
