In 1846, Carl Ludwig Koch created a classification of Phidippus, in which Phidippus variegatus (Lucas) and Phidippus audax (Htz) were considered separate species, with southern specimens considered Phidippus variegatus and northern specimens Phidippus audax.
However, the use of Phidippus audax was chosen and further research concluded that it was the same species.
In 2004, Glevis Bernard Edwards, a taxonomic tomologist who specializes in spiders, published a study that analyzed specimens of the worm Phidippus and estimated its taxonomic position.

Phidippus audax was placed in a clade with Phidippus princeps, Phidippus pulcherrimus, Phidippus bidtatus, Phidippus felinus, and Phidippus workmani.
These species were distinguished by the presence of partially vertical ridges in the central part of the palea.
Phidippus bidtatus is believed to be the closest relative of Phidippus audax because they share a synapomorphy where the male is concave sided.
The presence of a distinct white triangle on the back and two small spots below is often used to distinguish this species.

Black Widow Spider Bite: Causes, Appearance, Symptoms, And Treatment
The truth is that the black widow spider is a scary arachnid, at least for girls. Only the woman dies; Males and spiders (Arachnids), fortunately, do not appear. The old female black widow is the most venomous spider in North America; its venom is fifteen times stronger than that of a creeping snake. The black widow spider is known to eat the male after mating, hence the name “widow”. Scientists believe that the female sees the male as a source of protein needed for egg development. This type of behavior, sexual cannibalism, is actually rare in black widow spiders in the wild, but that hasn’t stopped it from being a big part of the spider’s personality.
Black widows are easy to spot. Just look at the shiny black spider with the red hourglass mark on its abdomen. Once caught in the web, the spiders hang upside down, waiting for insects, and their abdomens are visible. Bright red markings warn potential predators that black widows are poisonous and inedible. Black widows can be found in underground tunnels, under rocks, in wood piles, outhouses, and in dark, dry places like garages, basements, barns, and sheds. U
