Hi,

for me it looks like Neomochtherus but maybe it is not ... is it possible to ID?

A female Neoitamus sp. Looks like N. socius or N. cyanurus to me. Knowing the species is rather hopeless from pictures as far as I know. The development of microtrichia on the basal radial cell needs to be seen to separate both species.

However, sometimes a well experienced eye might be able to see something helpful. Wait for Reinoud ;)

Actually, it is not so hopeless. You can find very nice pictures of socius here

To me, this looks more like cyanurus.

Well, Theo, it seems this really needs an expertise eye ;) Certainly, not mine (I still have never seen any of both species in real life) and I wouldn't risk species ID. I only know 'the theory' ;) My idea was that only the microtrichia were diagnostic for females. I truly should keep my mouth shut :S :D

Piluca is a "wijsneus": ))))) Strictly she is right but a pretty reliable character is the colour of the metatarsi. In this case they seem totally black which would strongly suggest N. cyanurus.

Ok, thanks for the reply.

N. cf. cyanurus will continue to be :), if I collected it we will have a confirmation.

Best regards
