Horaga selina, the Selina's onyx, is a species of lycaenid or hairstreak butterfly found in Sulawesi, Indonesia.

[1] H. selina is endemic to Sulawesi.

[1] It was first found in the central region and was known until 1985 from only a single holotype specimen.

It has since been found in the southern region[1] and also in the Bogani Nani Wartabone National Park, northern Sulawesi, during the Royal Entomological Society's 1985 Project Wallace expedition.
