New comment thread
OK. I keyed my specimens with Robinson and Curran and have had some conflicting results. R. vanduzeei should have pale calypteral setae, but my male has mostly black setae (I don't know if a mix of black setae rules this out). Female vanduzeei should have yellow hind femur, but my specimen and this specimen have the apical portion black dorsally. The male genitalia of my specimen seems to match nothing but vanduzeei.

Robinson (the more recent key) has my specimens out to vanduzeei, so that is where I am tentatively placing them (mentally).

I am rather confused and will look closely at specimens in the USNM when I next visit.

Rhaphium vanduzeei Curran, female
Moved from Rhaphium. ID'd from specimen, now a photo-voucher. Thanks John.

 
Just curious: how was this fe
Just curious: how was this female identified to species seeing as brevilamellatum female is unknown and likely looks very similar?

 
Should be a "tentative ID"
Should be a "tentative ID" I suppose. Keys to vanduzeei using Robinson's key, which of course doesn't include the unknown brevilamellatum female. I may not have realized there was a close species when I keyed it.

While an argument can be made to leave this at the genus level, I think the odds are pretty good it is R. vanduzeei. R. vanduzeei is, based on collection records, widely distributed while R. brevilamellatum only has two collections, both in coastal localities (VA & NS), per Pollet's catalogue.

P.S. Would like to find a pdf of Curran's 1926-27 treatment of the genus if you know where to get one.

 
I found it here with a bit if digging

 
That is only the first half,
That is only the first half, the "concl." of the paper was published a year later and is not online in pdf form anywhere. I have access to a copy at the USNM reprint library which I will check.

 
Online now
I filed a support ticket with Google (saying it should be public domain) and got a surprisingly quick response. The volume with part 2 is now fully accessible.

Ah, awesome!! Thanks for doin
Ah, awesome!! Thanks for doing that. I forgot 1927 is now public. Annoying that I can't download it, though.

 
Here you go!
