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. 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. Colonus was declared a junior synonym of Thiodina by Eugène Simon in 1903, but this was reversed by Bustamante, Maddison, and Ruiz in 2015.
