Titel: Ozyptila male? => Ozyptila cf. confluens
Beitrag von: Raffaele Falato am 2020-11-13 19:07:08

Gorgoglione, Province of Matera, Basilicata, Southern Italy.

Discovery date: November 13, 11am.
Habitat: 700 m - in an oak forest, on the open space in front of an abandoned bungalow.
Dimensions: just over 3 mm.

Ciao,
this male of Ozyptila (I believe) was emerging from a small meadow of low grass.
Is it possible to determine the species (in Italy there are 16 registered) from the photos of the pedipalps?
Thanks.
Raf

P.S. I also add a photo of the sternum, maybe it can be useful.

Hello Raffaele,

Ozyptila sp. is correct.

Thanks Stefan.

Therefore, even in this case the sight of the apophyses does not help in the determination.  :-\

I have analyzed the coloring of the various segments of the legs of the 16 species of Ozyptila present in Italy, and I think I have come to something relevant.
My spider has legs III and IV only slightly shaded in some segments, well a similar peculiarity is present only in the male of Ozyptila confluens, as can be easily seen in the wiki, on araneae.ch and on the Pierre Oger website.
I would like to know your expert opinions.

Ozyptila confluens is pretty likely! I have found this species in autumn too and the tibial apophysis is spot on! I would write it down as cf. confluens.

Ozyptila confluens is pretty likely for me according to the habitus and the season. This is the only  Ozyptila male collected from me at November and it is especially common near buildings or in places with sparse vegetation.

Well, the apophyses have served and how.  ;)

The ventral section of the males, on the other hand, I no longer show it.

Ciao Maria,
you have described the habitat perfectly.

Thank you all.
Greetings from southern Italy.
