hi,
this morph is being bred here in Germany. A friend has a large breeding stock.

I personally do not believe that his is a 'morph'. All* the SoCal geos turn dark later in life. I had one that went completely black for a couple weeks before its death.

I saw this spider before he got it and it had the normal colors and patterns then. It is probably just a mature speciemen that has darkened.

*everyone I have seen/kept/heard about.

Here's a link to a post I did awhile back, showing some of the different colors I have found in my breeding stock.

hi,
what about the beige ones that stay that color?
There are definately different color morphs of Latrodectus sp. for example L. tredecimguttatus: Black ones (showing 13 spots until ultimate moult), standart with 13 red spots, specimen with spot forming a line...

Improver, I was referring to the specific population that his geo came from. They start out 'normal' and after maturity they begin to darken.

I have not seen any SoCal geos(the population his is from) that stay tan throughout their entire life. I am not disputing that there are morphs of Latrodectus species, just that it is a trait from this population to darken after maturity and I dont think it deserves the term morph.

well, this individual has been very dark the whole time ive had it, before and after a molt
