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

Excellent! This will definitely be used and referenced. :)

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)

Thank you Chris for this easy key. Also, thank you so much for providing resources related to Mallphora fautrix.

I've started posting these helpful guides on my Profile page...I always seem to loose them otherwise
