Genus Columbisoga Muir, 1921
Distribution: South America and southern India
Type species (in original combination): Columbisoga campbelli Muir, 1921.
This genus is divided into two subgenera, with most species in the nomative subgenus by implication.
Subgenus Columbisoga Muir, 1921 (Type species Columbisoga campbelli Muir, 1921).
Subgenus Columbisodes Fennah, 1963 (Type species Columbisoga (Columbisodes) saracura Fennah, 1963).
There are 13 species in this genus as follows:
Columbisoga campbelli Muir, 1921 - South India
Columbisoga chusqueae Muir, 1926 - Ecuador
Columbisoga filistylus Muir, 1930 - Bolivia
Columbisoga gynerii Muir, 1926 - Ecuador
Columbisoga gyneriicola Muir, 1926 - Ecuador
Columbisoga maculosa Muir, 1926 - Ecuador
Columbisoga merae Muir, 1926 - Ecuador
Columbisoga ornata Muir, 1926 - Ecuador
Columbisoga sacchari Muir, 1926 - Ecuador
Columbisoga tenae Muir, 1926 - Ecuador
Columbisoga tylotus Fennah, 1943 - Brazil
Columbisoga zapote Muir, 1926 - Ecuador
Columbisoga saracura Fennah, 1943 - Brazil
Columbisoga are mostly bamboo feeders (Poaceae: Bambusoideae).
Columbisoga chusqueae - Chusquea sp.(Poaceae: Bambusoideae)
Columbisoga gynerii - Gynerium sagittatum (Aubl.) P. Beauv.(Poaceae: Gynerieae)
Columbisoga gyneriicola - Chusquea sp.(Poaceae: Bambusoideae)
Columbisoga ornata - Gynerium sp.(Poaceae: Gynerieae)
Columbisoga zapote - Manilkara zapota (L.) P. Royen (as Lucuma mammosa C.F. Gaertn.)(Sapotaceae)

Host data from Muir (1926) as reported by Bartlett (2010).
Economic Importance: Limited.
This genus is a heterogenous group of taxa. The New World taxa are probably not monophyletic with each other or with the type species from South India. As New Species are described, it will likely be broken into new genera. Key to genus for New World taxa is found in Bartlett (2010). Most taxa were described by Muir (1926).
Species of Columbisoga often come to lights. I have examined large series of specimens, mostly undescribed.
