Latrodectus mirabilis, sometimes (but rarely) known as black widow is a spider species that is native to most of South America in the genus Latrodectus of the family Theridiidae.

Description

[edit]

Instead of an "hourglass" pattern on the ventral side of this species, this spider has a red rectangle on its ventral side.

Venom

[edit]

This spider's bite has never been recorded but as with other Latrodectus species most people think the bites are venomous and causes latrodectism.

Look-alikes

[edit]

The False Black Widow looks more like this species than any other in Latrodectus except the Brown Widow.
