Black Widow Spider

Latrodectus sp


Does anyone recognise this species? I found it in an arid region of the Andes; it had "glued" grass stems together forming a dome-shaped structure in which it built its web, the entrance was round and lined with silk; it first caught my attention because it looked like the entrance of a tarantula burrow, upon closer inspection I saw the inhabitant (latrodectus?). Unfortunately, I was unable to see its underside.


Arid region in the Andes, at about 1500m above sea level, in an area called "Desierto de Jubones".

Thanks Hema. However, I'm leaning more toward mactans without being quite sure...
