Moved

Moved

Moved from Spiders.

Thanks John - I added an image of the palp in clove oil that is much better and I think confirms the ID.

The new shot

is giving me pause, it actually looks more like D. olympiana to me. Chad also has a print copy of the paper, I'd like to hear his thoughts. I'll try to get a scan of the diagrams and email them to you if I get a chance.

Sure - no problem

but I think the distal part of the embolus looks much more like fig. 7 than fig. 5 on plate 41. I think it's correctly placed.

I think

this is either E. olympiana or E. serena and will trust Ken that it is the latter since he has the actual spider. I wish I could capture with pictures exactly what I see when I'm looking at a spider, but that just isn't possible at this scale. Nice find!

Thanks to both of you -

I checked the palp again, now with a paper copy of Chamberlin and Gertsch 1958 in my hands, and I agree with John that olympiana is the best fit. I added another image of the palp that shows an even U-shaped bend in the distal embolus that is present in figs. 1 and 5 of plate 41 and not seen in the illustrations of E. serena. Thanks again!

I left a note for Chad

There is a lot of detail in the printed diagrams that's not evident in the lousy scans of that paper. It's really a shame that some of the AMNH papers were so poorly scanned.

OK -

I understand - let me know what Chad and you ultimately conclude. I can always delete this species page... I've also ordered my own "hard copy" of that monograph. I'd be happy to move it back to the genus page, but would be reluctant to move it definitively to olympiana without re-visiting the palp and the monograph myself too... I'm very stubborn! :)

That's great that you found a copy of the paper

I would just leave this here till you have a chance to view the diagrams.

… John Rosenfeld, 31 May, 2015 - 2:47pm

Seems like the best match to me too

Using the print version of that paper.
