Two cicada hatchlings (Hemiptera: Cicadidae) in Burmese and Dominican amber are described as Burmacicada protera n. gen., n. sp. and Dominicicada youngi n. gen., n. sp., respectively. Although very similar in appearance, the two species can be separated by body contour, the nature of the process on the terminal antennomere and the shape and size of protrusions, teeth and spines on the forelegs. A comparison of the forelegs of the fossil hatchlings with those of an extant hatchling of the periodical cicada, Magicicada septendecim (L.), reveals a remarkable degree of morphological conservatism over 100 million years. A brief review of fossil cicadas is presented.
