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):) Very common at the moment here too. Regards, Niels.

Hi Niels. I expect Stephane will enlighten us ;)

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.

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