Bootanelleus orientalis, photographed by Gary Taylor and Matthew Purcell.

Belongs within: Chalcidoidea.
Contains: Megastigmus.

The Megastigminae is a group of wasps characterised by a prominent stigmal vein in the forewing. The majority of species are phytophagous, though many are inquilines or parasites of other gall-makers.

Characters (from Bouček 1988): Stigmal vein branching off marginal vein at a relatively wide angle, knob of stigmal vein unusually enlarged, which makes the vein distinctly longer than breadth of costal cell; basal vein mostly well pigmented with posterior end curved outwards; body often more or less yellow (rarely with metallic colour); thorax with rather sparse and usually outstanding conspicuous hairs, always without short normal pilosity; hind coxae relatively shorter than in other Torymidae; ovipositor tending to curve upwards, sometimes very strongly so.
