Using the online key, i arrive at Suillia bicolor. Is this correct?

Thanks in advance

I have found the hairs on the subscutellum which moves me in the direction of S. pallida / S. vaginata.

As far as I know/can find out, S. vaginata is not found (yet) in the Netherlands, which makes me a bit doubtfull.

Since the scutellum doesn't make the difference, the fore tarsal segment should make. What do you think of it?

Nothing more possible? I would really like to have this one named, and i thought we were close.

If I see it correctly, on the first picture, the hairs on the sternits are rather long and pale. So, my guess is S. pallida, which is not uncommon at all in the Netherlands.

To be sure 100% it is perhaps better to show us a good picture, laterally, on which you can see the hairs on the underside of the abdomen. Or prepare the genitals and make a picture of it.

I am only a few back from a business-trip to Germany. I was unable to check diptera.info since my last message in this thread.
I see nobody reacted. Andrzej, do you agree with my observation?

Sorry fot my lack of response. Was very busy myself the last days. I will try to provide the extra pictures tonight or tomorrow.

@Ruud, what book/articles do you use to determine the Suillia species? You are referring to different characteristics as the ones in the on-line key. Untill now i was unable to find any literature about the Suillia (Heleomyzidae), which is afforable for me.

I use an Hungarian key in the series Fauna Hungariae, written bij Laszlo Papp. I guess language may be a problem for you. I also use frequently the keys of Czerny and the key of P.Withers.

More detailed picture of the hairs on the sternites. They are really long and pale indeed.

Hope the picture above is detailed enough to confirm S. pallida.

Preparation of the genitals is still a problem for me. I am afraid i will destroy the animal completely since it is already dry.

@ Ruud. My hungarian is not to good indeed. I have found the references to the other to keys you mentioned. But i can not find any place on the net were i can buy them.

The works of Czerny are very old. You cannot buy them, I think. You try to get copies of them. I made mine in the Taxonomic institute of Amsterdam.

Well, Jan, the last photo is convincing me: it is pallida. Look at the long blond hairs on the sternits.

Thanks very much for the assitance. I guess i will have to visit a library soon if i want to have the right keys ;).

I have collected some other Suillia's so maybe i will call in your help in the near future.

You are not a member of the dutch entomological society? If you are they are willing for quite a small amount of money to make copies for you of the keys of Czerny. But the best is, I think, to go to the Plantage Middenlaan yourself and ask for the works and make copies yourself.

No Ruud, not a member (yet). Guess i will have to go to the Plantage Middenlaan one of these days :).
