Chromeurytominae

Male Chromeurytoma, from John Heraty.

Belongs within: Chalcidoidea.

The Chromeurytominae are an Australian group of chalcidoid wasps associated with plant gall-makers and leaf-miners.

Characters (from Bouček 1988): Antennal flagellum with just six segments between pedicel and clava; the first of which may be anelliiform, short, but not a true anellus. Female clava at least slightly asymmetric, with more or less oblique sutures and a collapsing area of weaker sclerotisation and with special short trichoid sensilla. Scrobal cavity evident but not well delimited, ending far from ocellus; in lower part divided by an interantennal crest. Parascrobal areas convex. Antennae inserted below lower ocular line, at the convex but not well defined clypeus, the lower margin of which is arcuately produced and stout. Both mandibles 3-toothed. Malar groove ending at a finely margined and sometimes slightly depressed mouth border. Occipital carina present, of torymid form, but occasionally obsolete (in one species). Surface of body generally shiny, mostly shallowly cross-striate to smooth, mostly sparsely pilose (hairs on papillae), mostly with metallic gloss but in at least two species the gloss is absent. Pronotum fairly large and quadrangular, anteriorly often edged or carinate. Scutum rather short and broad, with deep complete notauli; frenal line distinct but weak, situated far before the apex of the scutellum. Mesopleuron bearing peculiar pit-like depressions. Propodeum bearing medially a large, depressed, subtriangular to cordiform area, which is often divided by a median carina; median area is delimited on sides by converging channels marking on inner side the convex smooth plical swellings which laterally merge with postspiracular sulci; posterior to the median area is a very short nuchal ring set off by a transverse groove. Mid tibia with a rather long spur, often longer than the basitarsus; hind tibia with two spurs. In the forewing the stigmal vein has a distinct uncus, the postmarginal vein is often at least as long as the marginal. Gaster on a mostly visible petiole, basal three tergites large, third usually larger than second; gastral body is strongly convex. Ovipositor sheaths are usually distinctly protruding, up to as long as gaster. Cerci always elongate.
