Gorgoglione, Province of Matera, Basilicata, southern Italy.

Discovery date: 23 December, 13:00.
Habitat: 800 m - under a stone in a meadow with very low vegetation.
Dimensions: about 4 mm.

Hello everybody.
Another female (adult or subadult?) of Haplodrassus dalmatensis?
This spider seems to be the sister of this: forum.arages.de/index.php?topic=26390.0, and I found it the same day, a few stones away.
Thank you.
Raf

Good morning.
Since this thread is currently unanswered, I took a look at the forum and found these threads:

https://forum.arages.de/index.php?topic=22320.msg135757#msg135757
https://forum.arages.de/index.php?topic=16097.msg102499#msg102499

In light of them (as we lawyers say) for me there is no doubt about the identification: Haplodrassus dalmatensis.
Instead, I have doubts about the "age" and sex of the specimen.
Obviously, mine is the opinion of a neophyte, so I await the confirmation, or denial, of the staff and experts of the forum.
Greetings from Italy.

The problem is that we don't have experience with species distributed in Italy, but not in Central Europe.  In Central or Western Europe, H. dalmatensis can be determined by habitus (although I'm not super happy with such diagnosis) because there are no other species with this pattern. But in Southern Italy there are probably still undescribed Gnaphosids, so one should be very careful with determinations to species level just by habitus.

There is at least another Mediterranean Gnaphosidae - Haplodrassus omissus - which is closely related to dalmatensis (Haplodrassus dalmatensis pictus as depicted by Kulczyński also possibly shows this species). It has not been recorded from Italy (yet?), but given its otherwise wide distribution, it is at least not impossible.

Right considerations.
Haplodrassus cf. dalmatensis, then?
Or, more generally, Haplodrassus sp.?

I guess, it would be better to leave it at genus

Well, Haplodrassus omissus has never been reported for Italy. The only other Italic species that resembles my spider by habitus is H. signifer, but its dorsal design is only hinted at and not as evident as in my specimen.
I have already met this species, identified in Italy, and the "fish bone" is very little evident, so I have some reservations.
This does not mean that I can question your identification.
Haplodrassus sp., then.
Thank you all.
Raf

@Tobias Maybe you, the Staff and the experts have no experience with the Italic species, but for my spiders identified here on the forum, in Italy I have not had any answers.
Thanks again and a greeting.
