A new genus and species of froghopper, gen. et sp. nov. (Hemiptera: Cercopoidea, Sinoalidae?), is described from mid-Cretaceous Burmese amber. The new genus possesses the following diagnostic characteristics: slender, medium size body (length, 7.0 mm) with head longer than wide, round eyes; antennae slender with eight antennomeres; pedicel very short, shorter than scape; pronotum with a length/width ratio of 2.4; metatibia with three spines, including one short spine near base and two adjacent, long, thick spines near apex; a single series of 16 thick apical teeth (comb) at metatibial apex; tegmen narrow with a length/width ratio of 3.2; tegmen with coastal area and stigmal cell punctate; CuP meeting base of CuA2; and MP branching at middle of wing. In hind wing, Cu vein forked once. A series of plant trichomes adjacent and attached to the specimen suggests that the froghopper's host plant was a fern.
从白垩纪中期的缅甸琥珀中描述了一种沫蝉新属新种（半翅目：沫蝉总科，？中国沫蝉科）。新属具有以下鉴别特征：身体细长，中等大小（体长7.0毫米），头部长大于宽，眼睛圆形；触角细长，有八个节；梗节非常短，比柄节短；前胸背板长宽比为2.4；后胫节有三根刺，包括基部附近的一根短刺和顶端附近相邻的两根长而粗的刺；后胫节顶端有一排16根粗的顶端齿（梳）；前翅狭窄，长宽比为3.2；前翅沿海区域和 stigma 细胞有小孔；CuP 与 CuA2 的基部相交；MP 在翅中部分支。在后翅中，Cu 脉分叉一次。一系列与标本相邻并附着的植物毛状体表明，这种沫蝉的寄主植物是一种蕨类植物。
