Tolumnia variegata, commonly known as the harlequin dancing-lady orchid or variegated oncidium in English and as angelito or angelitos in Spanish, is a species of orchid native to the Caribbean.

[1] It inhabits both moist and dry forests at all but the highest elevations, and is the most widespread member of the genus Tolumnia.

The inflorescence grows to 40 cm (16 in) long, bearing up to 30 flowers.

[4] The flowers are highly variable in size, shape, and colouration, but are usually white (sometimes pink) with a yellow column and brown to purple spots on the labellum.

[5] T. variegata is an epiphyte that grows on the branches of trees and shrubs, including calabash, guava, citrus, and coffee plants.
