Mayfly Central Taxonomic Updates

[Taxon]

Mayfly Central’s North American Master Species List was updated on August 30, 2006. Thankfully, there were very few updates, and none of any consequence to fly fishers.

In any event, these were the updates:

Family: Baetidae
Heterocloeon amplum (Acentrella ampla) - species moved from Acentrella to Heterocloeon, ending changed to conform with gender of target genus

Acentrella barbarae - new species, Jacobus & McCafferty, 2006 [USA:SE]

Heterocloeon davidi - new species, Waltz & McCafferty 2005 [USA:SE]

Apiobaetis futilis (Pseudocloeon futile) - species moved from Pseudocloeon to Apobaetis, ending changed to conform with gender of target genus

Heterocloeon grande (Plauditus grande) - species moved from Plauditus to Heterocloeon

Heterocloeon rubrolaterale (Pseudocloeon rubrolaterale) - species moved from Pseudocloeon to Heterocloeon, ending changed to conform with gender of target genus
Family: Caenidae
Americaenis cusabo - new species, Provonsha & McCafferty, 2006 [USA:SE]
Family: Heptageniidae
Epeorus vitreus (Epeorus rubidus) - became subordinate synonym of Epeorus vitreus

Dicovered excessive verbiage pasting too late to correct it, but the following item should have read in the above posting:

Heterocloeon rubrolaterale (Pseudocloeon rubrolaterale) - species moved from Pseudocloeon to Heterocloeon

Incidentally, I have nothing whatsoever to do with Mayfly Central. However, it is the definitive source for N. American mayfly taxonomy. Whenever it is updated, customarily once or twice a year, I compare the current version with the previous version in order to understand the specific changes. This allows me to make updates to my website, as appropriate. And, having gone to that work, I attempt to share the changes on fly fishing entomology forums.

Nothing of consequence to fly fisherman?

I've been trying to catch a Pseudocloeon futilis hatch for years. I was about to give up and consider it just a futile expenditure of my time and resources, but with the change to Apiobaetis, I may just keep looking for a hatch.

Do you ever fish the Canis latrin hatch?

[Taxon]

wildnative-

Such a rare combination of humor and persistence should serve you well. In answer to you question, it's a bit difficult to fish a Caenis hatch, as they crawl out of water to emerge. However, you're spot on about it being "latr" when they choose to do it.

Could you explain the humpy hatch? I think the scientific name is humpus hard proportionus.

cheech-

There is no such thing as a humpy hatch. The Humpy is one of the more popular floating attractor patterns used when there isn't any obvious hatch. Hoping this information satisfies your need, whatever it might be.

[Cary]

You know, I keep telling him that but he wont listen. Always coming up with these patterns with wings that tip over,abdomens too long, etc., trying to match the hatch perfectly.

So we usually concentrate on the Adams hatch instead, it was real heavy this spring on the West Fork of the Allred.

You 'spose this guy's got a pocket protector?

[Tyson]

It is interesting in the book Hatches II how, after going into great detail on the various subspecies of mayfly, proceed to recommend only a handful of basic patterns to cover them all.

[RipRap]

....cause' that is all you need.

Wins my vote for the post of the year...

I'm peeing my pants right now.

I'm in the process of tying a humpy emerger. Pics will come soon.

Here Taxon is trying to be useful and you guys just rag on him. No wonder lucky bowa was sniffling the other day about this place being mean to him. Hopefully Taxon has a thick skin and will stick around to share his knowledge, pocket protector and all.

From his reply, I suspect Taxon caught the gist of cheech's post. It appears he can dish it out and take it. Good on ya Taxon. Nice to see your posts.

[Jason]

Taxon, thanks for the info. Its good to know someone is keeping track of this stuff. I find it interesting that they're still finding new mayfly species....even today. Maybe someday they'll have their own "hatch" name as well. Any idea on where these two were identified? Western or Eastern states?


* Acentrella barbarae - new species, Jacobus & McCafferty, 2006 [USA:SE]

* Heterocloeon davidi - new species, Waltz & McCafferty 2005 [USA:SE]

[Taxon]

Jason-

Acentrella barbarae was collected from Great Smoky Mountains National Park, North Carolina/Tennessee. Not sure whether (or not) Heterocloeon davidi was also collected there. However I do know that it was collected from a southeastern state [USA:SE].

I don't know about mayflies exactly but entomologists in general are usually of the mind that there are more species of insects NOT described than are.

jdubya-

That could apply to mayflies as well, at least in parts of the world (like Asia, for example), where they may not have been studied as intensely as they have been in North America and Western Europe.

Yeah, I had an off the cuff offer (about 5/6 years ago) to work with John Morse (Clemson) to do some Ph.D. work with caddis flies in Asia (China). I wasn't in a place in my life at that time to take him up on it.

Lonnie-

That would certainly have been an interesting opportunity. Ah well.

Yes it would have. It was a sort of right place at the wrong time sort of thing. My wife was getting her masters, we were newly married (just a few months), my salary was basically supporting us, I went several hours away to take a intensive 2 week E.P.T. class with Dr. Morse. I worked for local government at the time and there were several of us that worked in a bug lab there that was trying to get state certification. I had done quite a bit of bug ID work in the past. He had a new grad student who didn't show up for the fall semester. I was doing really well in his class and knowing I already had my masters, he asked me if I would be interested in working with him. Well, hell yes, but I didn't think I could swing it given the logistics of the situation (two married folks in grad school at schools 3.5 hours apart, yeah that's going to work....) That was my best and most likely last chance to go for the Piled Higher and Deeper.....

But at least I can say I was taught by the guy who wrote the caddisfly chapter in Merrit and Cummings....

Lonnie-

Very interesting; thanks for sharing.
