Review of the Asian leafhopper genus Scaphomonus Viraktamath (Hemiptera: Cicadellidae: Deltocephalinae: Scaphoideini) with description of a new genus and new species
Abstract
The Asian leafhopper genus Scaphomonus Viraktamath is reviewed, with one new species S. bispinosus sp. nov., described from Malaysia (Sabah and Sarawak). A new genus, Selangomonus gen. nov., is described for three new species i.e., S. bruneiensis gen. et sp. nov. from Brunei, S. falcatus gen. et sp. nov. and S. undulatus gen. et sp. nov., both from Peninsular Malaysia and for six species, previously placed in Scaphomonus, i.e., Selangomonus flataedeagus (Li) gen. et comb. nov. from China; S. furcatus (Xing & Li) gen. et comb. nov. from China, S. indicus (Distant) gen. et comb. nov. from Myanmar, S. longistyleus (Li & Wang) gen. et comb. nov. from China; S. naejangsanus (Dutta, Kwon, Suh & Kwon) gen. et comb. nov. from Korea and S. splinterus (Li & Wang) gen. et comb. nov. from China and Thailand. A key is provided to the Scaphoideus group genera which, in addition to Scaphomonus and Selangomonus treated here, includes Scaphoideus Uhler (in part), Melanetettix Knight & Fletcher, Scaphoidella Vilbaste, Scaphomonoides Li, Dai & Xing, Parascaphoidella Wei, Fang & Xing. Of these, Scaphomonoides is newly assessed, based on a specimen of its type species, S. redstripeus (Li & Wang), from Vietnam (new record). In addition, a review of the usage of Scaphoideini in the literature and characters defining the tribe, are provided.
