I wonder if this is the invaria rotunda variant or not even in the invaria complex.
I am not a entomologist but it is a odd one.

I agree, Mack. I think this is excrucians (PMD in the West, Little Red Quill in the MW). Its tiny size and darker color are in line with the Midwestern form of the species. IMO this one isn't that close to the usually paler and much larger invaria. I can't explain why it was placed there other than by mistake.

BTW - reference to invaria as invaria rotunda is misleading. In this case on two counts. First, the way it is written implies a subspecies taxonomy that doesn't exist. Secondly, if rotunda were still a valid species, it would never be confused with a dark fly smaller than 5mm. Just for clarification in case anyone reading this thread was getting confused.

Right. It was synonymized awhile back. While older names are very useful for reference when discussing variations within a species (even if only so that older descriptions & keys can be referenced), to use them in topics where these issues aren't relevant only adds confusion to no purpose. For example, lets say we were discussing Epeorus species in a topic and the name Iron fraudator (Quill Gordon) was introduced from a reference in an old taxonomy. If we then began referring to the genus Epeorus as the Iron group or the species pleuralis as pleuralis fraudator in other unrelated topics we would be doing a disservice to the rest of the forum participants. Even when they are relevant we shouldn't probably string them together in italics with valid names. Again, not only are we implying that obsolete names are still valid we are also implying a subspecies taxonomy that doesn't exist. The Latin is tough enough as it is... We may understand each other's shorthand, but we confuse other people enough already, Mack!:)LOL

That makes great sense. That will be the plan my man :-)

Yes it has, thanks for pointing it out! I suspect there's a lot of older entries in need of revision.

If I find them as I will, I will pull them forward to you with a question.
