Psorthaspis - Psorthaspis sanguinea - female

Psorthaspis - Psorthaspis sanguinea - Female

would this be a Psorthaspis sanguinea... looks much like P. mariae, but i would call these wings infuscate, i have not managed to find a picture of P. sanguinea... perhaps due to my inferior computer skills.

P. sanguinea, I would call the wings more than infuscate, I'd call them HEAVILY infuscate...and no your computer skills aren't inferior. This genus is rather uncommon and there just aren't many images out there. I'll go ahead and move it to the guide page I've just created, I hope you don't mind.

P. sanguinea
mind, not at all... i am rather pleased that i got a picture that made you create a new guide page, it has become a new goal of mine. i just wish i had gotten better pictures of the P. mariae i saw a few weeks ago while hiking, if this genus is not so common. by the way do you happen to know what spiders this lady was after? i have been seeing it for a while now on the hunt... but have yet to see it with a spider.

Herschel is correct...
the only known prey record for this genus is the western P. planata, none of the four eastern species have known prey records. They are all adapted in the structure of the legs and prothorax for the purpose of getting into the burrows of these spiders. I would LOVE to have a prey record for any of the four eastern species. I think trapdoor spider get less common as you go north, so in Arkansas this genus is probably much more common than in say, Ohio (I've only seen seven Ohio specimens). I also suspect P. mariae is actually distributed throughout much of the south (although I'm not sure about the coastal plain...the distribution of most species is little reported).

If you see one of these with a spider Edward, shoot a shot or two but then take them both and put them in alcohol. I will personally come get them.

wasps and spiders
well i do try to always keep my eyes open... so, on the off chance i might see something in this genus take a spider, i will do what it takes to collect it.

There are no mariae proven for AR though I have it listed. There are several sanguinea in the collection from Washington and Johnson counties. I have never seen a comment on the prey species except in the western planata which tears open trap door spider homes and frontally attacks the big trap door species.

I took a poor shot of the sanguinea specimens last year. I will get a better shot this winter. There are likely none on the web anywhere on the planet.

P. mariae
no P. mariae proven for arkansas... i will send you some very, very bad pictures i took around the buffalo river last month, and see what you have to say about them. also, any wasp that charges a trap door spider is impressive, to say the least.

This exchange of comments
is one of the reasons BG is so inspiring. A photo that doesn't exist anywhere on the planet's Internet is very cool to see and to think about.

Congratulations to Edward T for the photo and thanks to each of you for exchanging the info.

thank you for the kind words Jack.
