A remarkable new sinoalid froghopper with probable disruptive colouration in mid-Cretaceous Burmese amber (Hemiptera, Cicadomorpha)

The Mesozoic froghopper family Sinoalidae was reported from the uppermost Middle-lowermost Upper Jurassic Daohugou Biota and coeval strata of northeastern China, and mid-Cretaceous Kachin amber of northern Myanmar. Herein, a remarkably new sinoalid froghopper, Omatiala amoena Chen, Wang and Zhang, gen. et sp. nov., is reported from Kachin amber. The new taxon is distinctly different from all known sinoalids in possessing the following characters: the head strongly produced anteriorly, slightly longer than wide; the pronotum relatively long, with length/width ratio about 0.6; the tegmen with post-claval margin beyond termination of CuP strongly convex, making tegmen widest near termination of CuA(2), and a long stalk ScP+R+MP present. Additionally, this new remarkable sinoalid bears a novel prominent colouration pattern (probable disruptive colouration) on tegmina, further confirming that this froghopper group was likely to be undergoing high morphological and ecological diversification in the mid-Cretaceous.
