Is this Hedychridium roseum or a close relative?

Postby briang » 25 Oct 2021 10:40

I found these images from 6 July 2020 in a folder labelled “unidentified Chrysis”. One year later I think it may be a Hedychridium, and because of the non-metallic abdomen, perhaps roseum or a close form. Can anyone confirm the correct genus? Is species ID possible? Apennine foothills, Piacenza Province, Emilia Romagna, Italy. Thanks for any advice!

Yes, Hedychridium in the roseum-group, the second image shows the shapes of the genae from above, which is an important character in these species, so perhaps it's possible to ID it to species

Alex, thanks very much for replying. Happy to know I’ve made a little bit of progress in recognising some of the more obvious chrysidids! I’ll try and follow up on that genae character. Don’t know if you recall naming Spintharina for me last year but I was fortunate to get back to that site a few times this past summer; lots more sightings plus Celonites (but couldn’t find nests of the latter!). Thanks again.
