Colonus is a genus of spiders in the jumping spider family, Salticidae. Colonus species are endemic to North and South America, ranging from New York to Argentina.[2] All members of the genus have two pairs of bulbous spines on the ventral side of the first tibiae. The function of these spines is unknown.[2]Colonus was declared a junior synonym of Thiodina by Eugène Simon in 1903, but this was reversed by Bustamante, Maddison, and Ruiz in 2015.[3]
