Treehopper taxonomy changes

The following should be changed, per Matt Wallace, one of the treehopper experts for the eastern U.S.:

- Ceresa festina is Spissistilus festinus
- Acutalis brunnea is a synonym of A. tartarea, the valid name
- Ceresa palmeri is Stictocephala palmeri
- Ceresa lutea, C. stimulea, C. basalis, and C. diceros are in Stictocephala (can't speak for the other Ceresa)


all the guide pages under Ceresa have been updated to reflect the current species placement according to the fragmented classification, whereby our Ceresa s.l. got scattered among as many as four genera (Hadrophallus, Spissistilus, Stictocephala, Tortistilus).
now BG searches for combinations used in recent publications will lead to proper pages [make sure to check the 'guide' checkbox]

Glad to hear this worked out well. Take care

the synonymy is mostly reflected on guide pages, and with membracid taxonomy in flux we have reasons not to make some changes pending a more thorough and definitive taxonomic overhaul that is expected to involve redefining several supraspecific taxa.
[i'm not an expert by any means, though, but will ask Dr Hamilton to chime in]

Andy responded immediately:
"Barcode data does indeed support the synonymy of Acutalis brunnea = A. tartarea; but not the separation of Stictocephala and Spissistilus from Ceresa (Stictocephala is paraphyletic with respect to Ceresa and Spissistilus).
"There are lots more changes coming to Membracid genera, none of which will please the conservatively minded; least of all those who had a part in making the too-fine divisions of genera.
"But first, I have to get folks used to such changes. I have several MSS in the works for simpler changes in leafhoppers and spittlebugs; once these are accepted, then I can tackle the more serious changes to treehoppers."

That's fine
Just wanted to give the heads up. I believe that Matt Wallace and Mark Rothschild are at the head of this change in membracid taxonomy, as they have published some papers on this

are you in touch with Matt Wallace and Mark Rothschild? could you please list the recent papers affecting the membracid taxonomy? we will include them in the BG ref section.
also, for any such papers not available online, could you ask the authors to share digitized copies so we can update the guide pages to reflect the relevant info and site the sources of the new data properly?

I am in touch with them. I think the papers should be available online, but this I believe is the main paper citing the new taxonomy:

thanks again --i made an entry
...and will digest the info for the guide pages

I understand that Andy thinks differently than Matt and Mark do in terms of treehopper taxonomy. I didn't want to stir anything up here

no problem
one cannot possibly raise an issue like this and stir nothing: non est regia ad taxonomiam via...

[could you please click 'edit' and select 'Taxonomy Proposals' from the Forum dropdown list to move this thread where it belongs? and thanks again for your great job in the hopper section!]

And thanks!

love the Deitz & Wallace paper --terrific job putting together the checklist, summarizing the records, and analyzing the biogeography! most helpful for the Guide, will quote it profusely.
among other things, i'm very impressed by the faunal richness of the northeastern states, as compared to the southeast: close to 120 spp. in NY, 80 in CT, 90 in MD vs 66 in FL and 25-27 in AL, MS, LA each! talk about tropical groups...

Glad to hear that
