Today two phaonias on picture.
species a: might be P. fuscata-female
species b: might be P. perdita-female

This identification is based on the marks on thorax, witch i compared with the pictures on this website.

Any help by identification is welcome

Thanks in advance, Klaas

Species a is a female Phaonia tuguriorum.
For species b, I'll need to see whether there is posterior setae on fore tibia.

Species b looks like P. errans, it seems that there are 2 pairs of acrostichals before the scutellum, (anterior ones broken or very weak ?), and frontal triangle narrow and reaching anterior part of frons...

last picture- first pair acrostichal brists is clearly broken.
ergo P. errans

Thank you Stephane

Our messages have crossed. I am convinced that it is P. errans now (we can even see the rows of proclinate setulae aside the frontal bristles, and no posterior setae on t1 - OK). :)
