It has interesting wing venation for a chalcid, doesn't it (I have limited experience)? Nice specimen, really interested in what it is!

Hi

Its an Omalus spec. - if the specimen would have been spotted in Germany i would say its Omalus auratus, but i'm not sure which similar species occur in Hungary.

Cheers

Hi!

With this color on the head an thorax it colud be Philoctetes (formerly Omalus) horvathi, especially if the picture was taken somwhere in the Hungarian Plain. But it is just a guess.

Regards,

I think, in fact, that P. horvathi is the only “Omalus” in Hungary with bronze color or similar hue over most of the body. The pattern of punctuation, as far as can be seen on the photographs, does not contradict this ID. Still, it’s an opinion of an amateur, and it would be nice if an expert could give an opinion about this wasp, because Philoctetes horvathi is not a common sp. (Nice photos, I think!)

Regards,

Henrik

Hi

As far as i could assess it in the pix it seems the hairs on the Thorax are quite long. Other Omalus s.l. have shorter hairs in my opinion. Well the colour doesnt really fit for auratus because the thorax is so bronze which havent seen yet for auratus but i know that auratus has a considerable colour variability.

By the key of Mingo (2004), horvathi is a species with short hairs on body. But it is difficult to decide about length of hairs on a photo. On the other hand, the only species in Central Europe with bronze shimmer is horvathi. The other species, as auratus or pusillus have a markedly different color or color pattern.

I send photo to a specialist, maybe we will get a better result.

Paolo Rosa wrote:
"The specimen in your picture is not horvathi, but it is the most common Cuckoo-wasp in Hungary: Pseudomalus pusillus. In the Budapest Museum collection there are some hundreds specimens. The specimen in the picture is only a male with an unusual color. To be honest it is not so unusual, in fact often males (and occasionally also femalas) have some green-coopery parts shining red. In general they loose this metallic red colour after the death, and it remains only on scutellum and metanotum."

ah interesting... for me the post-scutellum looked relatively rounded so i though its not pusillus - but auratus & pusillus are sometimes not too easy ...

I do not see many Chrysidids in Hungary, cc. 5-10/year although our country is supposed to be good place for them. But I usually see more green/red species than these all green species. I think these are particularly tough to spot.

Thx for the help for everyone to get the id.
