Very likely to be a female of Geomyza balachowskyi. Normally (but not always) the abdomen the females of G. hackmani and G. martineki is entirely black (with the exception of the base), and in those species the post-scutellum is normally also much darker.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
