Little Salticidae in the wood => Aelurillus sp.
« am: 2021-09-11 11:13:07 »
Gorgoglione, Province of Matera, Basilicata, Southern Italy.

Date of discovery: August 24, 11 am.
Habitat: 700 m - on the ground, among the dry leaves at the edge of a road that crosses a wood of Turkey oaks.

Ciao,
what genus of Salticidae is this little spider?
Is it a sub-adult male?
Thanks.
Raf

Aelurillus by the looks.

Thanks Simeon.

It should be Aelurillus v-insignitus then, the other 2 Italic species look different from the photos on the web.

But is it an immature male or a female?

The pattern of the prosoma resembles that of the female, the palps to those of a sub-adult male.  ???

I am very reluctant to identify immature and female Aelurillus from habitus. Adult males are distinctive most of the time. Yours appears to be an immature male - I have said this many times: most male spiders attain their typical "male" look only after the last moult, prior to that they look like (immature) females.

Well, thanks again Simeone.

As immature I classify it Aelurillus sp.

I reopen the discussion because I have a question to ask.

Are the short white stripes under the lateral front eyes (present also on my spider) a typical feature of female and immatures of Aelurillus v-insignitus?
Because I don't know if these stripes are present in the other 2 species of continental Italy: monardi resembles luctuosus (which has no stripes), of schembrii I have not found the description.

These white stripes are a good character to disitinguish A. v-insignitus from Asianellus festivus females/juveniles. However, many other Aelurillus species have these stripes as well. It's more a genus specific character than a species specific one. If you have a look at Micha's collection (https://kleinesganzgross.de/gallery.php?Gattung=Aelurillus) you'll see that these stripes are present in most Aelurillus species... in some more prominent than in others, though.

Best,
Benjamin
