Theridiidae on wild fennel => Kochiura aulica
« am: 2021-07-12 13:18:09 »
Gorgoglione, Province of Matera, Basilicata, Southern Italy.

Discovery date: 10 July, 12 noon, sunny and very hot.
Habitat: 800 m - in the countryside, in its web on the top of a very tall wild fennel.
Dimensions: just over 3 mm.

Good morning.
Is this spider a female of Anelosimus vittatus or Kochiura aulica?
Thanks.
Raf

Thanks Simeon.
I also thought of Kochiura, instinct immediately led me away from Anelosimus but I don't know why.

What do you base your idea on? You know that every detail is very precious to me.
Thanks again.

I don' know the species myself, but the wiki says:

"[Opisthosoma] Ventral mit einem dunklen Rechteck (gesäumt von breiten weißen Band auf jeder Seite), ausgeprägt von der Epigastralfurche bis zu den Spinnwarzen, neben denen sich jeweils zwei auffällige Punkte befinden. (Locket & Millidge 1953)" (http://wiki.arages.de/index.php?title=Kochiura_aulica).

So there should be conspicious dots lateral to the spinnerets, which are clearly visible in your ventral picture. The wiki lacks a ventral picture of Kochiura, though...

There is a ventral picture of Anelosimus vittatus in the wiki (http://wiki.arages.de/index.php?title=Anelosimus_vittatus#/media/Datei:Anelosimus_vittatus_ventral_Lemburg.jpg) and I don't see these dots in it.
