Maculergithus, a new subgenus in Gergithus Schumacher, 1915 with two new species from northern Vietnam (Hemiptera: Fulgoromorpha: Issidae)

By Jérôme Constant and Hong-Thai Pham


The new subgenus <em>Maculergithus</em> subgen. nov. is established to accommodate two new species of the genus <em>Gergithus</em> Stål, 1870 (Issinae, Hemisphaeriini): <em>G. (Maculergithus) tamdao</em> subgen. et sp. nov. and <em>G. (Maculergithus) luteomaculatus</em> subgen. et sp. nov. from Tam Dao National Park in North Vietnam. Two more species from Hainan, China, <em>G. multipunctatus</em> Che, Zhang &amp; Wang, 2007 and <em>G. nonomaculatus</em> Meng &amp; Wang, 2012 are also placed in <em>Maculergithus</em> subgen. nov. A fifth species from Hainan, yet undescribed and erroneously identified as <em>G. multipunctatus</em> in recent papers also belongs to this new subgenus. Illustrations of habitus, morphological details and male genitalia together with a distribution map and an identification key to the species of <em>Maculergithus</em> subgen. nov. are provided. Four species of the genus <em>Gergithus</em> are now recorded in Vietnam. A rectificative note on the misinterpretation of <em>G. multipunctatus</em> in recent publications on Issidae is also provided
