Holm (1991c) provided a diagnosis of the genus, a key to the eight known species, information on their types and distribution patterns. Since this date some species were restablished as bona species and a total of sixteen species are now recognized (see updates in Beinhundner 2017a). Only one species was recorded for Angola until now ( Ferreira 1965, Beinhundner 2017a) and another one is recorded here for the first time.
