New fossil Procercopidae (Hemiptera: Cicadomorpha) from the Middle Jurassic of Daohugou, Inner Mongolia, China

摘要

Anthoscytina Hong, 1983 is the largest genus within the Mesozoic Procercopidae, the stem group of the superfamily Cercopoidea. Herein, we describe two new species from the Middle Jurassic of Daohugou, northeast China. Anthoscytina brevineura Chen, Wang & Zhang, sp. n. and Anthoscytina elegans Chen, Wang & Zhang, sp. n. are established on the basis of new well-preserved fossils. Although these two new species are very similar, some stable differences in tegminal venation and colour patterns confirm their species status. Sinotettegarcta longa Hong, 1986 is transferred to Anthoscytina, and to avoid secondary homonymy, a new name Anthoscytina hongi Chen, Wang & Zhang, nom. n. is proposed for that species. In addition, Anthoscytina aphthosa Ren, Yin & Dou, 1998 and Anthoscytina macula Hu, Yao & Ren, 2014 are transferred from Anthoscytina to Stellularis Chen, Yao & Ren, 2015.
