Beitrag von: Raffaele Falato am 2020-11-11 18:08:48

Gorgoglione, Province of Matera, Basilicata, Southern Italy.

Date of discovery: November 7, morning.
Habitat: 800 m - in the countryside, under a stone in a meadow with low vegetation and shrubs, nearby there is an oak forest.
Dimensions: the largest 3-4 mm.

Ciao,
I found these two spiders in their shelter (I have the photo, if needed) under a large isolated stone in a small meadow.
I have no idea, I can only imagine that the largest spider is a male and the other a female / young.

Thanks Simeon, I had never met these spiders.
Can you tell me when I can find adult specimens?
Thanks again.

Uh, maybe in spring? Around May? My experience with Titanoeca is only sporadic.

Rearranging the photos, I found this one that appears to show an apophysis or something similar on the left palp.
Is it therefore also present on juveniles (the photo concerns the largest spider)?

No, this is not an apophysis but a white object on the palpal tibia creating the illusion of an incision. The spider is a sub-subadult male by the way. This said, in Cybaeus for example, the patellar apophysis starts developing as a small pointed protrusion even in subadults.

Mai/June is good for almost all subadult spiders in autumn/winter. In Italy probably even already in April.
