help me out

re: "Tribe Rhamphini. Isochnus, Orchestes, Rhynchaenus, Tachyerges"
=====================
In my copy of American Beetles (4th ptinting), Rhynchaenus is listed in the index, but not Rynchaenus – however, believe it or not, neither name could be found in the body text, not even among synonyma.
nearctica.com lists all the species placed here (in the BG) in the Rhamphini under Rynchaenus (no ‘h'!); the spelling sounds weird, but the concept is more familiar than the one adopted in the Guide. Canada and New Hampshire checklists have them all under Rhynchaenus. Florida’s uses the Rhynchaenus–Isochnus–Tachyerges scheme.

Isochnus, Orchestes, and Tachyerges are defined in American Beetles; but what species, if any, should be placed in Rhynchaenus under the 4-genus arrangement proposed by Phillip?

Anyway, if we follow the current BG’s scheme, ‘Rhynchaenus salicis’ page should be moved for consistency to Tachyerges; it definitely belongs there. Moreover, I suspect, whatever non-salicis images sitting now on the Rhynchaenus page must go to Orchestes page.

you noticed that too

per your comment "In my copy of American Beetles (4th ptinting), Rhynchaenus is listed in the index, but not Rynchaenus – however, believe it or not, neither name could be found in the body text, not even among synonyma." - my copy is similar, puzzling. I included Rhynchaenus on the checklist, only because it was in the guide and I wasn't sure what the current status of those species are. I perhaps should have put a question mark on it. Mike or Charlie no doubt know.

This problem isn't noted in the known Additions and Corrections either.

i see -- thnx

anyway, it's clear that under 3-genus arrangements Rhynchaenus and Orchestes mean the same thing and are used interchangeably, but when everything in under one roof, then Rhynchaenus seems to be the name of choice...

Rhynchaenus is evidently obsolete for our species

my understanding is that those species previously in Rhynchaenus have been spread among the three others. So, it isn't a one to one synonymy. I'll see if I can't get a current list that shows where the 16 or so Rhynchaenus went. This may explain why it shows up in the index of American Beetles [index wasn't updated] and isn't strictly speaking a synonym of any one genus.

I guess we'll need to move the unidentified Rhynchaenus to tribe

current nomenclature [preliminary]

Rhynchaenus [or Ryn..] in the older North American Literature are now (Current combinations and syn. not verified, conflicting info seen) -

Genus Orchestes
alni (Linnaeus) (=testaceus (Mueller) per Canadian List)
betuleti Horn - Type
canus Horn - Type
griseus (Sleeper)
mixtus Blatchley
pallicornis Say [1 subspecies pallidior] (=canus Horn?)
testaceus (Mueller) (=canus Horn, scutellaris Fabricius as noted in British List or syn. of alni Linn.)
scutellaris (Fabricius) (syn. of testaceus Mueller?)
Genus Tachyerges
ephippiatus (Say)
niger (Horn) - Type
rufitarsis (Germar) [or Isochnus sp.?]
salicis (Linn.) (=subhirtus Horn Type)
Genus Isochnus
arcticus (Korotyaev)
flagellum (Ericson)
illinoisensis (Fall)
parvicollis (LeConte) - Type
populicola (Silverberg) - Adventive, Canada, Northeast US
puberulus (Boheman)
rufipes (LeConte) [1 subspecies minutus] - Type
uniformis (Brown)

There are several images under genus Rhynchaenus, below are some thoughts on where I believe they need to be moved:

This appears to be Orchestes canus [valid or syn. of testaceus, pallicornis or calceatus (Germar)?] - note ".. the three denuded spots" on the elytra [JC] Compares well with type.

These look like O. alni (Linn.) [valid or syn. of testaceus?] - European Elm Flea Weevil. A recently noted adventive species here in NA [evidently first seen in 1982].

I can't see enough detail. Move to tribe or..

I guess we still need an image of any Isochnus sp., unless this is one? Appears that the initial ID was I. populicola.

it's great what you did with these guys

frankly, most of them did look to me suspiciously nostalgic :) -- alni was among weevils i used to catch around my house in Moscow back in 1970 when I just started collecting. i just couldn't say it aloud...

… v belov, 28 October, 2008 - 8:20am

moved and updated, but

current list. Also see here - any opinion?

… Phillip Harpootlian, 29 October, 2008 - 10:57am

impossible to believe they may be conspecific

in my experience, the jumping guys (to avoid calling names :) feature pretty consistent and species-specific color patterns

… v belov, 29 October, 2008 - 11:04am

thank you, Phillip!

That's one most helpful improvement. Now, could you think of a way to find out names for a couple of apparently common entimines currently sitting under the 'Temporaryone' and 'Temporarytwo' pages? I also have a couple of questions I would like to ask you privately, Phillip. My addr is vmarfus gmail.

IDs

According to Jan;

"Those in the upper right and elsewhere, with large rounded elytra with two dark elytra fascia and pronotal vittae, are Pseudocneorhinus bifasciatus Roelofs. The ones in the top row center and the rightmost two in the bottom row look different (narrower elytra), but there's not enough there to identify.

Those on the second page look like Pandeleteius hilaris (Herbst)."

will e-mail.

Outstanding once again Phillip

A great way to see the family at a glance and link right into the guide!

… john and jane balaban, 19 October, 2008 - 4:11pm

Yes,

wow, nicely done Phillip.
