 Another one, and it looks like something related to the previous one.

Is there a key to subfamilies online? Or some other aids?
I don't want to be guessing every time I find a specimen looking rather unfamiliar to me.

 I'd say Tanytarsini. You could try the Nearctic Manual for generic identifications -

I think most of the chironomid genera are Holarctic.

 Tanytarsini are tough. At least, I haven't figured out how the genera differ in superficial appearance.

 Great manual, many thanks. I'm happy when I'm able to separate the subfamilies properly... Wink

 Most Chironominae can be distinguished from most members of other subfamilies by the long front legs with fore basitarsus longer than fore tibia. There is some overlap with the more primitive Orthocladiinae (Brillia group). If the fore basitarsus is 20% longer than the fore tibia, it is Chironominae. If the fore basitarsus is less than 90% as long, it is not.

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
