the antennomeres do look rather long in the first picture (less so in the last one though) so I would lean towards P. triangulifer, but I can't confirm it really

The chrysidid was found in an old orchard on the leaves of a plum tree on 5th May 2024. The body length about 6 mm. I presume that it is a Pseudomalus sp. (P. auratus?, P. triangulifer?). Could anyone help with the ID? Thanks!

Hi Milo,

yes, you're right,
it's a Pseudomalus.
Then the question is always the same, auratus or triangulifer?
This could be triangulifer, because in the first picture it seems that flagellomeres are elongate ...

Cheers

Thank you for your reaction Paolo. It's the same problem as always: they are to quick in flying and I was lucky enough to get some shots. So I'm happy with Pseudomalus, auratus or triangulifer.

Hello Hedy,

the images are too small to check diagnostic characters.
It's a Pseudomalus, auratus or triangulifer.

Cheers

Can this Chrysid be named..?
Found 3-7-2021 in Zeist, Holland

Thank you Paolo for the kind explanation and thank you Alex. I too lean to auratus, I have caught and identified triangulifer before and do think this specimen has different antennal segments matching with auratus.
Kind regards, Jochem.

Hi Jochem, thanks for your pictures. The distinction between Ps. auratus and Ps. triangulifer is not always easy and immediate, and needs experience. The easiest way to separate the two species is looking at the lenght of the antennal segments. If the median flagellomeres ...

Hi Miroslav,

Nice pictures. I think it is Pseudomalus triangulifer for the elongate flagellomeres.

Cheers
Paolo

Thank you very much Paolo !
