A new species of Sinoalidae from the topmost Late Jurassic Daohugou Bed (Hemiptera, Cicadomorpha)

The extinct froghopper family Sinoalidae Wang & Szwedo, 2012 is one of the early representatives of Cercopoidea (Wang et al., 2012). Sinoalidae is rich and diverse taxonomically and morphologically, comprising eighteen valid genera, thereby being the most diverse member at generic level among three Mesozoic families of Cercopoidea. It has been reported in the late Middle to early Late Jurassic Daohugou biota from northeastern China (temperate zone) and the mid-Cretaceous amber biota from northern Myanmar (near-equatorial region) (Hong, 1983; Wang et al., 2012; Chen et al., 2018), indicated that they could adapt to a variety of paleoclimatic environment.
