I thought this was a large black and green fly when I first saw it peering at me from a stump top. Only the face and chelicerae were visible. Only after I came and sat near it did it flash the red abdomen. This appears to be a large male Phidippus princeps. I can't make it into anything else with the flashy but fairly plain abdomen. It acted like it owned this stump.

From the same individual. Showing the all black face with the green fang covers.

And a Ouachita county male. Also showing the fang covers and more prominent male leg markings in white.

The magnificent Phidippus putnami male. Extreme front leg ornamentation and facial color. Almost unmistakable.

Top shot, same individual showing the upper markings.

Likely a female P. putnami with the white triangle on the head and the near richmani pattern on the abdomen compared to Edwards' drawings. I have yet to find the male right here near my house.

Female of the Phidippus mystaceus, one of our other widespread state species. And a fairly common eastern species. Those finely striped sidewalls are fairly distinctive in the female. Also, she is very hairy, even her shadow. Originally I called this a P. otiosus and they have strong similarities. The spider guys Hollenbeck and Cadle from bugguide convinced me that this and the below female are all a variation of the female mystaceus. The trio of spots across the top of the head are more characteristic of mystaceus.

Another female Phidippus mystaceus, this one from Round Mountain. I downed a large dead pine tree and apparently it was her home. Note the sawdust in her hair.

Dorsal markings of the same female mystaceus, similar somewhat to purpuratus but that would be an uncommon find in our state, though it has been recorded. Much more similar to asotus of the SW and very different from the other versions of otiosus as pictured in G. B. Edwards revision of the genus.

And these are the dorsal markings to compare which are the classic pattern of the female mystaceus, very similar to the one pictured in G. B. Edwards revision of the genus.

Compare the face, also from the Perry county female, to the mystaceus above from Round mountain.

And this is the dorsum of the male Phidippus mystaceus (see female forms above) from my front yard in Faulkner county on Round mountain. Seems to have reduced red markings compared to the east coast males. Very bright leg contrast with the blackish thorax.

Male face, same individual. Can be much more strikingly black and white. This one also seemed muted. But what a face.
