摘要

The Psylloidea is selected as the sister group of Coleorrhyncha-Heteroptera. The Dipsocoromorpha, Gerromorpha, and Nepomorpha are determined to be a monophyletic taxon by the possession of a synapomorphy, i.e., the hypopleurites of abdominal segment VIII that evolved to an appendage-like structure. A new formal relationship hypothesis in the Coleorrhyncha-Heteroptera is proposed with the Psylloidea as the sister group: (Coleorrhyncha + Enicocephalomorpha + (Leptopodomorpha + Cimicomorpha + Pentatomomorpha)) + (Dipsocoromorpha + (Gerromorpha + Nepomorpha)).

選本蝨總科為鞘吻群－異翅目之姊妹群。鞭蝽次目、龜蝽次目與蝎蝽次目判定為單系分類群，以其帶有近裔共性－第八腹節下側片演進為附肢狀結構。以木蝨總科為姊妹群之新的鞘吻群與異翅目次目間假設關係建議為：（鞘吻群＋奇蝽次目＋（細蝽次目＋臭蟲次目＋蝽次目））＋（鞭蝽次目＋（龜蝽次目＋蝎蝽次目））。
