Gorgoglione, Province of Matera, Basilicata, Southern Italy.

Date of discovery: November 15, late morning.
Habitat: 600 m - under the pebbles of a small stream.
Size: 7mm measured.

Ciao,
I found this specimen of Pardosa (amentata?) under a pebble lying on the mud of the river bank.
Is it a sub-adult male?
Thanks.
Raf

No, this is morosa/tatarica and so may be the females.

Hi Simeon, thanks,
but are you sure about sex?
Look here:

It's the same as my spider, isn't it?

The ones in the other posts with visible palps are females.

It does look identical but Pardosa tatarica (https://araneae.nmbe.ch/gallery/photos/1182) is closely related and also has black palps, even if the patellae there are not white. Maybe this is important during courtship display?

Well, all cf. morosa, then.
Do you agree, Simeon?

As for your question about the white color of the kneecaps and its function, I'm certainly not the right person to answer you.
Let's see if anyone else can say more.
