Amaurobius sp.? => Amaurobius cf. erberi
« am: 2020-02-06 18:31:47 »
Gorgoglione, Province of Matera, Basilicata, southern Italy.

Discovery date: 9 January 2020, 11:00.
Habitat: 900 m - under a stone slab of a low wall, on the outskirts of the village. All around, scarce and low vegetation, rubble and debris, some isolated young trees.
Dimensions: 1 cm or slightly more.

Greetings from Italy to the "spiderlovers" friends of the forum.
Here I am with another specimen of Amaurobius. This time I really think it's an adult (female) spider, considering the size, but I can't once again identify the species.
Thanks for your help.
Raf

P.S.: If the spider is identified, as I hope, I would be happy that my photos are used for the wiki.

 What about Amaurobius ferox?

Thank you guys.
However, after taking a look at the wiki and the araneae.nmbe site, as a neophyte I would better see A. jugorum, it is much darker and almost spotless on the opistosome like my spider.
Is there a reason you excluded this species?

Yes; the greyish nuance and the slightly flattened abdomen, as well as the rather short legs. I am quite familiar with erberi, as well as ferox (close to jugorum)

Well, very well.
I am fully satisfied with both the complete identification of the spider and the "morphological" explanation.
I will immediately change the thread title.
Thanks again.

Checking the country list for Continental Italy at Araneae.nmbe, I hesitantly think that the other Amaurobius can be excluded - they either belong to the ferox group (which are different - more bulbous, longer legged) or are closer to fenestralis (which would mean a different habitus). But I am not 100% sure as I don' t know all of these species, especially those around obustus

Please don't determine Amaurobius based on habitus alone. It's not sure that all the Italian species are described, especially in the south of the country.

@Tobias.
You are definitely right.
Southern Italy, in particular, is a true eldorado of nature.
Hello to all.
