Moved

Moved from Bryoporus rufescens.

Staphylinidae: Tachyporinae: Bryoporus rufescens

Pretty sure that this is Bryoporus rufescens. It is a quite common species in NH.

… Donald S. Chandler, 10 December, 2005 - 9:37pm

Bryoporus testaceus

Please see my forum post for details on this easily understood mis-identification.

But let me ask, how in the world can you see the elytral punctation on either this image or Tom's, which has since been determined by Adam to be in a separate genus? All I can see are a few pollen grains.

Hmm, more backpeddling...

As I mentioned in my forum post, I agree with Adam that id'ing mycetoporines from photos is something of a crapshoot, so take any name with a grain of salt. As we can't see the apices of the meso- and metatibiae nor other useful characters, we have to rely primarily on the process of elimination and Don's knowledge of the New Hampshire fauna. Given its locality, habitus, and coloration, it seems perfectly reasonable that this is either Carphacis or Bryoporus testaceus. After looking in the collection and at Campbell's revision again, I guess I'd have to lean towards Carphacis (either C. intrusus or C. nepigonensis: as Adam has mentioned elsewhere, you can't tell). While the elytral punctation in B. testaceus is irregularly sized and arranged, there are quite a few of them and you would think that more might be visible in this picture. In C. intrusus and C. nepigonensis there is a row of punctures about 2/3rds of the way between the elytral suture and margin, otherwise the elytra are rather glabrous and impunctate. I may be completely imagining this, but after blowing the picture up 400% it seems like there is a hint of this row of punctures visible on the upper elytron.

Still, at the end of the day, it's hard to say anything conclusive and you might consider "demoting" this image to simply Tachyporinae (Mesoporini).

… Zack Falin, 19 November, 2009 - 11:44am

OK, I'm imagining a puncture row there as well

so we're leaning in the same direction. I'll move this to Carphacis. Maybe Don will come back with some objection.

OK, I just checked my earlier images of this genus. I was struck at how much the body type resembled Lor*dithon, and I must say that this individual does not :-[

Thanks Don.

That one had been waiting nameless for quite some time.

… Jim McClarin, 10 December, 2005 - 10:05pm

It doesn't look like anyone has a genus species guess for this, so I'm moving it to the guide page. Let me know if you would rather leave it in the ID section.

Makes sense.

That's where any staphylinid expert would go anyway.
