Holochrysis dichroa (Dahlbom)

Hi Alexandru and Pascal,

yes, it is a male of dichroa Dahlbom.

The distinction of the genera in Chrysidids is not easy and there are different interpretations.
C. dichroa is considered as Chrysura by Kimsey & Bohart (Chrysidids of the World), Strumia (Fauna Italiana) and Niehuis (Fauna Eur). I usually follow Kimsey & Bohart for practicle reasons. But probably the best way is given by Linsenmaier, who considered dichroa belonging to a different subgenus (Chrysogona Foerster) within the genus Chrysis.

I won't use the name Holochrysis anymore for different reasons.
- it as a synonym of Chrysura Dahlbom and Chrysogona (if you follow Linsenmaier);
- the name Holochrysis has been given by Rye as an invalid emendation of Olochrysis Lichtenstein, 1876;
- it is not used after Berland & Bernard (1938)

Usually in the Forum we follow Strumia's Italian checklist (with few differences in Elampinae). You can find it (with addictional notes) on http://www.chrysis.net or http://www.faunaitalia.it/checklist/

Best Regards
Paolo

ooopss

dalla forma della capsula genitale non sono così sicuro che si tratti di dichroa, ma di laevigata.

Cosmin, prova a controllare la forma della capsula con i disegni di Linsenmaier che ti ho mandato (figg. 254-255); con l'esemplare sotto mano puoi confrontare meglio la sua forma.

Dopo che ho studiato Linsenmaier, come ha detto Paolo >>> C.laevigata.

Una foto per la comparazione:


Si può confermare C.laevigata (Abeille de Perrin, 1879) ?
