Thanks, Simone but look at the image of Eudoynerus in bie.ala.org.au/species/urn:lsid:biodiversity.org.au:afd.taxon:6ceea4ca-1f99-46c8-8a3e-7eb8e3dd305b
I think the ALA images for Stenodyniellus are a better match https://bie.ala.org.au/species/urn:lsid:biodiversity.org.au:afd.taxon:66dae0dc-2189-49b1-a7f3-5b5d659d0085#gallery I tried keying both out using the new key from Carpenter & Brown but it’s difficult to separate them without very clear photos of the thorax from side on, it does indicate we are picking between the right taxa (given there are no images for some). So we have to rely on overall impression, coloration etc
Thanks RAllen, those images are helpful. I think the last one shows the last two parts of the thorax (the metanotum and propodeum) are raised to the same level which would be the case in Stenodyneriellus. @Birdy what do you think?
