Mallos female? - Mallos pallidus - female

Mallos female? - Mallos pallidus - Female
Stulsaft Park, Redwood City, San Mateo County, California, USA
August 1, 2010
Size: 3-4 mm
This female had a distinct purplish hue to the abdomen - it was beat from a California Bay tree.

I originally thought this was Nigma linsdalei based on similarities in the epigynum, but I was later corrected.

M. pearcei actually looks closer
The range is more southerly but I think you are close enough. The drawing is ventral but it shows the internals and they seem to match yours.

Edit: I see you have one posted there that has a very similar epigynum.


 
Hi John -
Thanks for looking at this one - I'm really appreciating your help with my spiders! I don't think the internal ducts look similar to pearcei though. At the time (2013), I thought this female looked quite a bit like niveus (and also close to pallidus), but it's not mapped in CA, and I emailed Dr. Opell with the images, but he never got back to me.

 
Back to pallidus -
looking carefully at both Bond and Opell and Chamberlin and Gertsch, both emphasize that pallidus has a divided cribellum and mians and pearcei (the only other two species in CA) have an undivided cribellum. Also, pearcei has only been reported from extreme southern CA, while pallidus is widespread in CA.

 
Having found a male pallidus
would reinforce the likelihood. I Would have to agree with you.

Probably M. pallidus
based on the drawings in Chamberlin and Gertsch, 1958. Pattern matches and ventral epigynum matches. Unfortunately no internal epigynum drawing. Shows as in range. I have a print copy of that paper, the online version was scanned improperly unfortunately.
