Introduction

Evanioidea comprises three extant families, Aulacidae, Gasteruptiidae, and Evaniidae, and several fossil taxa of uncertain placement. Some systematists have uncovered morphological (Naumann 1991, Whitfield et al. 1989, Gauld and Bolton 1988, Gibson 1985, Carlson 1979, Crosskey 1951), biological (Gauld and Bolton 1988, Crosskey 1951, Bradley 1908), and molecular (Dowton and Austin 2001, Dowton et al. 1997) evidence questioning the monophyly of Evanioidea, but no formal higher level taxonomic alterations have been made since Hedicke (1939).
