Which Ballus? => Ballus rufipes
« am: 2020-06-24 11:55:42 »
Gorgoglione, Province of Matera, Basilicata, southern Italy.

Discovery date: May 5, 12:30.
Habitat: 800 m - on the outskirts of the village, on the iron railing at the edge of the road. All around there are houses, vegetable gardens with fruit trees, varied vegetation.
Dimensions: 3.5mm.

Hello,
I have trouble identifying this Salticidae as it is the first time I have encountered this genus.
Is it a male of Ballus chalybeius or of Ballus rufipes?
Thank you.
Raf

Based on what I see of the leg III and IV, it should indeed be Ballus rufipes and not B. variegatus (after Alicata & Cantarella 1987)

Thanks Tobias,
I didn't know there is a third species that creates confusion. On the web I have not found photos of variegatus.

There is even a fourth (armadillo) but it has no markings like this on the legs.

Yes, armadillo I had discarded it for the very reason you underline.

I noticed that the wiki page dedicated to Ballus rufipes presents the photo of a sub-adult male.
If you administrators want, my photos are at your disposal.
