Taxonomic review of Sphenoclypeana and cladistic analysis of Ischnorhinini (Hemiptera, Cercopidae, Tomaspidinae)

摘要

Ischnorhinini currently comprises nine genera: Baetkia Schmidt, Homalogrypota Schmidt, Ischnorhina Stal, Laccogrypota Schmidt, Neosphenorhina Distant, Schistogonia Stal, Sphenoclypeana Lallemand & Synave, Tiodus Nast, and Typeschata Schmidt. A phylogenetic analysis is presented for defining the relationship between the genera and between the species of Sphenoclypeana, and this genus is revised and two new synonymies are proposed and the monophyly of Sphenoclypeana was corroborated. The data matrix comprises 47 characters: 31 relating to the external morphology, 10 to male genitalia and six to female genitalia. The analysis resulted in one cladogram with 102 steps CI = 0.50 and RI = 0.66.
