Hello!

I would be very interested if someone cut put a genus or species name on this little critter. It is one of the most common Psocoptera here in Ostwestfalen/Germany, but I haven't found any information on it. Thanks!

Thanks Nikita,
Is there anything you don't know about?

If he doesn't know I bet he'll find out. IMH(newbie)O Nikita's knowledge seems to have improved over the short time I've spend here at diptera.info. I can see the dedication to his mission when reading threads like the one about how he photographed the mouse-fly :)

We could go further if we learn a) number of antennal segments, 13 or 15-40; b ) pterostigma sclerotized or not; c) number of segments in labial palpi and tarsi...

Hi,

I attached a 2zip-files with HiRes JPG's (2). That's the best I can do. Doubt if it helps, but hey...:)

I think it Valenzuela flavidus (Caeciliusidae [= Caeciliidae]). The only image I could found on the internet (http://www.mybito...kfly1.html) does not agree with the images and descriptions in my English key.

Quoting from the British key:

...one of the most abundant arboreal British psocids. Male are extremely rare, but parthenogenetic females are abundant and very widely distributed on foliage of broadleaved trees. It is rare on conifers. The life histories of this and related species in southern England were outlined by New (1969d, 1970a). Bisexual populations have been reported from Austria, Greece, Madeire, Norway and Switzerland (Lienhard, 1998), and the United Status (mockford, 1993).
