Hi again,
I was pretty sure that it was Aphantohaphopsis starkei, but FaEu does not give this species to any country bordering Lithuania, while it is very common in the material of all Malaise traps from the deciduous forests that I have studied during recent yeras. I hope that somebody will confirm this.

Hi!

I guess you have used the key in Andersen (1996)? Although being easier than Siphona, for me both Aphantorhaphopsis and Ceranthia require some staring under the scope to be sure. But yes, bare R1 and missing marginals on T1+2 favor starkei and does not seem to appear in combination in the others.

As for FaEu: In my experience, malaise traps are basicly only means in getting these species, sometimes in surprising numbers. So I wouldn't be too astonished. ;)

Theo will probably add some data, but congratulations anyways!

I have no experience with A. starkei.

I guess Erikas is sure about the genus, from what I see on the pic I cannot see all features.
Supposing it is Aphantorhaphopsis, I cannot exclde selecta and supposing it has 4 post DC, it still just might be verralli. I do seem to see 1-2 pores of setulae on the top part of vein R1. Setulae are easily lost in malaise traps. Some clues

Verralli:
third antennal segment in male distinctly longer than frons (difficult to judge from this pic), Tegula reddish-yellow

Starkei:
Third antennal segment shorter than frons. Epaulette black.

That should be easy to see.


Please let us know the results

Dear Jaakko and Theo,
I have alomost all box of them, while all specimens were carefully checked and noone has setulae on R1. Four postsutural dorsocentrals, tegula blindish black and first flagellomere in males exactly as long as frons. Photo of male head is bellow (first was female).

Erikas


It seems you could be right.
I cannot help you more online.

Since you have more material, you might share one male so i can have a 'real' look at it.

Give me a PM if your are interested sharing material.
