Male Chrysis comparata-group

Postby Arno » 13 Dec 2020 17:32

Hi forum,
On May 25th 2018 I collected this Chrysis male in my garden in the south-east of the Netherlands.
I looked at the next species which have a blue/violet collored apical rim:
- Chrysis graelsii does not match because the mesoscutum is medially not dark blue but light blue/green colored and the malar space seems too long.
- Chrysis analis has not such pointed teeth on the apical rim. Tergit 3 is quite long for C. analis.
- Chrysis marginata should have more golden-greenish tergits? I don’t have any documentation about this species.
Can anybody help me to ID this goldwasp? :thanks:

Hi Arno,

I don't think that this specimen belongs to the comparata group.
Could you:
1- dissect this male and take a picture of genitalia?
2- take a picture of flagellomeres and abdomen ventrally (to see the black spots on S2)

thanks
Paolo

Hi Arno,

thanks for your pictures.
The general habitus is that of the ignita group, but the genital capsule looks unusual.
If nobody else can identify this specimen, you could send it to me for a better examination under the microscope.

Ciao!
