Latrodectus tredecimguttatus, color variations
BLACK:

Chris, is that an all black morph? (...looks like it) Where was it collected? Do you have a strong line of those going?

:worship:

Hi,
yes thats an Black morph from Spain,
i have also Black morph from Israel.
Yes i have a very strong line of this;-)

Interesting. Have you tried crossing the two? Technically same species or possible sub-species?

 

[Canth]

Wow those are cool.

Wish I had some of those

Hi,
i have tried crossing color variation of spain, israel, france, italy, and from
other european countrys.
different color variants came out.
All this variations are the same species.
Some time ago some people have black morph of tredecimguttatus as revivensis, lugubris, spec. ex. Almeria and lilianae sells .
All this was tredecimguttatus.

Thats is what I suspected. Thanks for the info.

DJ Almighty-

Are you sure that last girl is a rev? She is gorgeous anyhow, but how old is she? I thought L. revivensis was solid black as an adult and more or less "fuzzy." Give us more info on that girl!

 

[Gigas]

your saying looks more like tredicemguttatus colour morph, i wass thinking this.

word. exactly.

Only if she's an adult though ...

 

[DJ_AlMighty_247]

Hey!

Here is a new pic after the molt. The spots are leaving and it looks a little bit "fuzzy" to me? :? Ls. about one inch. I think she's about 3 months old.

yes, now that looks much more like a revivensis. it was just the color, the still distinctive spots, and the lack of "fuzz" that threw me off at first.

It was my understanding that it's very hard to distinguish the revivensis from the Black Morph tredecimguttatus, perhaps even only with a microscope and knowledge I don't have?

If there's a key, I'd love to know it. I have some slings that I'm unsure about...

Hello,
me times to interest who determined your animals as revivensis?
As far as I know come all animals from the same
Source from Israel.
And these animals were determined as tredecimguttatus.

Yes, this what Steven and I have been discussing. Could be that none of us have revivensis, at least on this side of the pond?

Or thats all we have is revs.

In Israel, both are common ...back yard finds ..sort of deal. I was told that they can be found together. If I recall correctly, the revs take the high structure and the treds take the low ground. (?) I would suspect that webbing can even be shared where the two meet.

Behavioral issues are confusing me with my two all black lines. Revs should make web cones with extraneous materials attached much like pallidus. Neither of my lines do this. The treds i got from Todd do build tent like structures with prey carapaces and other junk, but I wouldnt compare their webbing to pallidus.
My "revs" dont seem to do much with extraneous materials. And to confuse me further, not all the treds have made those tents either. Now... we have to remember that spiders in cups, jars and even larger enclosures are not necessarily going to perform as they would in nature.

So... the best thing to do is for all of us that have fully black Mediterranean and mid-east species is to "meet" via PMs and discuss the background of our lines. Then we need to send samples to someone that is willing to ID them properly. Once we know what we have, we then can start observing each lines behavioral differences while in captivity. We will most likely find all kinds of differences even between the same specie but collected from different areas. BUT, we cant assume a specie is what it is because a dealer sold it as that specie. And we dont want to start (which unfortunately, I and others have already have) describing specie behavior and requirements before we know what we actually have.

Hello,
here some pictures of one “revivensis”,
those show that it over tredecimguttatus act;

 

[buthus]

Chris, interesting photos. do you have something to compare against the treds?
Love to have you explain in further detail what your showing us.
