The female black widow spider usually has a prominent red hourglass figure on the underside of its abdomen. Note that not all adult female black widows exhibit the red hourglass on their abdomen-some may have a pair of red spots or have no marking at all, but any markings that are present are bright red.
Several related "widdow" spiders from the Latrodectus genus of spider, in the family Theridiidae (to which all black widdow species belong) have similar markings but not all of them are on the underside of their abdomens - for example the redback spider of Australia has a red stripe on its back (which is where it gets its name), and the Latrodectus pallidus - which has the English name of "white widdow spider" has no marks at all, rather the white widow spider is light-coloured, with colouration ranging from beige to white, though with darker legs.
The female black widdow spider usually has a red hour glass marking on the underside of its abdomen.
