Systematics and distribution of world hyptiogastrine wasps (Hymenoptera : Gasteruptiidae)

New Evanioid Wasps from the Cenomanian of Myanmar (Hymenoptera: Othniodellithidae, Aulacidae), with a Summary of Family-Group Names Among Evanioidea

“…Since the works of Bischoff (1927), Hedicke (1930Hedicke ( , 1939aHedicke ( , 1939bHedicke ( , 1939c, and Crosskey (1951Crosskey ( , 1962, the most consistent classification considers the superfamily to comprise three extant familes-Aulacidae, Gasteruptiidae, and Evaniidae (e.g., Mason, 1993;Grimaldi and Engel, 2005;Sharkey et al, 2012). The monophyly of evanioids is abundantly supported in analyses of morphological and molecular data sources (e.g., Dowton and Austin, 1994;Dowton et al, 1997;Vilhelmsen et al, 2010;Sharkey et al, 2012;Payne et al, 2013), and they are also one of the few superfamilies for which there have been comparatively comprehensive modern phylogenetic studies and revisions (e.g., Aulacidae [Jennings and Austin, 2000;Smith, 2001;Turrisi, 2006Turrisi, , 2007Turrisi, , 2014Turrisi et al, 2009;Turrisi and Madl, 2013], Gasteruptiidae [Jennings and Austin, 2002;Macedo, 2009Macedo, , 2011Zhao et al, 2012;Achterberg and Talebi, 2014], Evaniidae [Deans and Huben, 2003;Deans, 2005;Deans et al, 2006;Kawada and Azevedo, 2007;Mullins et al, 2012]). …”

Entering behavior of Gasteruption brachychaetum Schrottky (Hymenoptera, Gasteruptiidae) into a nest of Hylaeus Fabricius (Hymenoptera, Colletidae)

“…In this case, the gasteruptiid larva behaves as a predator, consuming almost the entire tissue of the larval bee and later feeding on the host's food (Malyshev 1966). The family was recently revised in the Neotropical Region by Jennings & Austin (1997, 2002 (Hyptiogastrinae) and Macedo (2009, 2011.…”

Gasteruption youngi sp. nov. (Hymenoptera: Evanioidea: Gasteruptiidae)<br />from South Australia; an unusual species with trichoid sensilla on the ovipositor sheaths

“…A small number of Gasteruption L. species, however, show various degrees of occlusion of the discal cell (see Crosskey 1962;Jennings & Austin 1994;Macedo 2011). In Hyptiogastrinae, 1-Rs+M intersects the basal cell about one-quarter to one-third of the distance from M+Cu (Jennings & Austin, 2002), although the discal cell is completely missing in Pseudofoenus Kieffer species from New Zealand, 1-Rs+M and 1-Cu(b) being fused to form Rs+M+Cu(b), and veins 1-M and m-cu being absent (Jennings & Austin 1994). Jennings & Austin (2002) provide a more detailed comparison of the two subfamilies.…”

“…Gasteruptiidae (Evanioidea) is divided into two subfamilies, Gasteruptiinae and Hyptiogastrinae (Jennings & Austin 2002). They can be separated most readily by the first discal cell in the vast majority of Gasteruptiinae being formed by fore wing vein 1-Rs+M forming a node at 1-Rs, M+Cu and 1-Cu (Fig.…”

“…Hyptiogastrinae, which comprises Hyptiogaster Kieffer (10 spp.-mainland Australia), and Pseudofoenus (79 spp.-largely Australasian in distribution, except for two South American species), has been revised recently (Jennings & Austin 1997, 2002, 2005. As with Gasteruption, Hyptiogaster have long ovipositors, but in the sister genus Pseudofoenus, the ovipositor is very short and hidden by the ovipositor sheaths.…”
