Here in the USA we have a spider called a Black Widow, that also eats the male. They look very similar.

I used to hunt these spiders for entomologists to milk for anti-venom. Here their bite can kill. Interestingly, their web is unreasonably strong, and that helped my locate them. You can feel the single strands of silk snap in this web, and you know you have a Black Widow.

Be Blessed!
