Very teneral.

at BugGuide I do notice. I'm curious as to what keys and/or what reference collection (CMNH?) you are using. Keep it up!

Also, I had most of my Amara sitting in trays undetermined for quite awhile. This past summer I had a period of clarity with that difficult group and it all seemed to make sense to me. I either saw things clearly and got them right or they are ALL miserably wrong. So, don't hesitate to ask me about any thing that doesn't look right to you.

I've adopted my own keys for PA using Bousquet (2010) when ever possible (I like the quantitative nature of his keys). It has taken me about 18 months to get it mostly finished. There are still many bugs to work out and there are still a few species which I need to find reference specimens for to work them in the key. For Amara I am able to use Bousquet's keys for the most part. I have collected a pretty good reference library to work with. When I really get stuck on something I can usually find reference specimens at the Academy of Natural Sciences in Philly.

for me. Reasons are: many members are morphohologically difficult to distingush AND no one else seems to be taking on the challenge of the North American fauna after the unfortunate demise 8/12/2015 of the leading world expert Fritz Hieke (Berlin, Germany). I'll try to look closer at you images, but in the case of Amara, it me be impossible to be sure without the specimen under my scope. My personal reference collection holds about 50% of the 105 known Nearctic species. Let me know if you have specific questions.
