7.5 mm, Arncliffe Yorkshire UK, 5 June 2011

I found this in a moribund state indoors. Gregor's key leads me to H. impuncta, but according to the description the fronto-orbital plates should be touching. The paired spots on t2&3 look strong when lit from behind, but less so in the photo. I couldn't get much reassurance from the genitalia, but they look as close to H. impuncta as to any of the other spp. illustrated.

I think about Helina impuncta too, but can't confirm, as I have too less experience (I'm just interested)Smile Very common at the moment here too. Regards, Niels.

This is an odd one. As far as I know, with prst acr., it can only be Helina impuncta or Helina quadrata (rarely in H. lasiophthalma one can find 1-2 elongated prst acr.).
With 1+2 ks and bare eyes, I can't see anything exept H. impuncta.
Stephane.

Thanks Stephane! I'm glad I was right to be puzzled.

at least now you can find out!

yes, from the Neotropical. It is still an open question whether these are really Chvalaea.
