Description
Stiromesostenus ranges from small to moderately large, with forewing length of 4-12 mm. Most species are reddish brown in colour and several have darkened wing apices. The antennae have white bands in the middle.[3]
Ecology
Wasps of this genus are parasitoids of Lepidoptera. Stiromesostenus rufus has been reared from an unspecified "fern moth" larva.[3] Stiromesostenus albiorbitalis attacks the macadamia twig girdler, Xylorycta luteotactella (=Neodrepta luteotactella) (Xyloryctidae).[4] An unspecified species of Stiromesostenus have been reared from Uraba lugens (Nolidae)[3]
