Which Araneidae? => Gibbaranea gibbosa
« am: 2020-07-30 12:16:32 »
Gorgoglione, Province of Matera, Basilicata, southern Italy.

Discovery date: May 16, noon.
Habitat: 900 m - in the village cemetery, on the ground. In the immediate vicinity there are cypresses and some other kind of tree.
Dimensions: about 5-6 mm.

Hello,
Is this spider a Gibbaranea male?
And if so, is it possible to determine the species from the photos?
Personally, I have the doubt between gibbosa and omoeda.
Thanks.
Raf

Thanks Simeon.

A variant of  pattern, I suppose.

Is there any feature that can allow me to identify it next time without help?

Greetings from southern Italy.

Gibbaranea males have large palps and huge complex median apophyses - except Gibbaranea gibbosa (and Gibbaranea bruuni, which however doesn't occur in your region). And there are some differences in habitus, spine thickness etc.
