Parahiraciini (Hemiptera, Fulgoromorpha, Issidae): one new genus, two new species and three new subtribes

A new genus Pusulissusgen. nov. with two new species P. phiaoacensissp. nov. and P. coronomensissp. nov. are described respectively from Vietnam and China in the tribe Parahiraciini of the family Issidae. A molecular phylogeny using combined genes (18S, 28S, COX1 and Cytb) confirms its placement in the tribe Parahiraciini. The tribe is divided into three subtribes: Scantiniinasubtribe nov. with the type genus Scantinius Stål, 1866, and Vindilisinasubtribe nov. with type genus Vindilis Stål, 1870 plus Nisoprincessa Gnezdilov, 2017, and the nominal subtribe Parahiraciina Cheng & Yang, 1991 subtribe nov. The characteristics of these subtribes are provided, with a key to identification. Genus Folifemurum Che, Zhang & Wang, 2013 is transferred to HemisphaeriiniMongolianina, and genus Gelastyrella Yang, 1994 is maintained as a valid name.
