This is a very basic key, only looking at one character (color/pattern of abdominal setae) but it seems to work consistently.

I wish there was a way to add journal posts to "favorites"...or is there?

@pfau_tarleton
The best you can do is "Subscribe" near the bottom of the page. The second best you can do is to leave a comment.

More seriously, I also feel a need to "collect" journal posts like one could "collect" favourites.

Updated the key to include a species newly added to iNat, Mallophora atra. The scutellum, if you're not familiar, is the posterior section of the thorax (see #12 http://geller-grimm.de/morph/morph04.htm)
