ID help on photo from North Carolina?
Do you think this:
is an
Archodontes
or a
Stenodontes/Mallodon
? Eric Eaton thought it might be a female
Stenodontes
, but was not completely certain. I can't quite tell from the description and photos in Yanega.

I had moved the images up to the subfamily level pending some more help.
Thanks for any assistance.

Mallodon
is diagnostic - pronotum with sides arcuate, mandibles pointed forward (not downward) and antenna inserted from projection.

Dorsal view please
For ID purposes on the guide pages it would be nice to have a straight dorsal view. Please post one if you took one.
We found just one pseudoscorpion on a Harlequin Beetle in Ecuador. Looks like this guy was loaded. Discovery is always a nice aspect of photography.

Sorry... what I posted is all
Sorry... what I posted is all I've got. There's not much to the dorsal view that can't be seen here in this particular specimen, but next time around I'll do a straight dorsal for the site. Most of what I put here is low-rez versions of stuff I shoot for professional purposes, and dorsal views aren't popular with drably-colored insects so I usually don't do them. I'll do 'em for this site, though. It's been a huge help to me in the last year or so.
I hadn't known much about pseudoscorpions before, and now I'm fascinated. They've got chelicerae modified into pincers, like true scorpions, but that are connected to venom glands, like spiders. They seem like they could be a sort of link between the Araneae and Scorponida in that sense. Amazing, the little details we overlook in everyday life when it's the details that make it so interesting!

Art vs. science!
I know what you mean about dorsal shots not exciting customers. I live for the shots of impressive features and interesting behavior in a natural setting, but I'm working on a database of New Hampshire beetles that will be used to find the identity of the beetle in hand (or jar), and for that, a dorsal view is almost always important. Often, the *shape* of the elytra is the best way to distinguish between species. This site is similar in purpose, so I try to post views that will be most helpful in ID work.
The pseudoscorpion/longhorn relationship is an example of interspecies dependency that I find very intiguing as well -- like the dung & carrion beetles and their mites.

Neat--moved to species level
I'd already written a guide for this species, trying to differentiate from
Stenodontes
. I've moved your photos to the species level, and added a common name, hope you don't mind.
