The Neotropical genus Oligactis contains 13 species grouped in two subgenera: Andromachiopsis and Oligactis. Subgenus Oligactis has four species that occur mainly in Colombia and one of them reaches Central America and Venezuela. New synonyms Oligactis garcia-barrigae and O. valeri are proposed under the species O. volubilis and O. sessiliflora, respectively. The synonyms Liabum meridense, O. biattenuata, and O. boyacensis are tranferred from O. volubilis to O. sessiliflora. O. volubilis is illustrated for the first time. In addition, a key to the species of the subgenus Oligactis is provided.
