Giants trapped in resin: new material of Sinoalidae in mid-Cretaceous Kachin amber from northern Myanmar (Insecta, Cicadomorpha)

摘要

The cicadomorph family Sinoalidae was documented in the late Middle to early Late Jurassic Yanliao Biota from northeastern China and mid-Cretaceous Kachin amber from northern Myanmar. The known sinoalid froghoppers contained in Kachin amber bear a much smaller body size than their Jurassic relatives. Herein, two new sinoalids trapped in Kachin amber, with a relatively large body size, are described and ascribed to Makrosala elegans Chen & Wang gen. et sp. nov. and M. venusta Chen & Wang gen. et sp. nov. The Burmese amber is now recognized as a significant window to the Cretaceous world, but taphonomical biases should be kept in mind when studying the ecology, biodiversity, and community composition and structure of this amber palaeo-biota.
