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

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...

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).
