The scientific name of the species was first published in 1972 by Lieftinck. Lieftinck based the species on specimens in museum collections collected in 1928 at the village of Siwi by
Ernst Mayr, and in 1957 at the village of Sururai by Hardy. The species has been reported only twice more, by S. Lamberts near Mokwam in 2011 and by Marco Langbroek near Syoubri in 2016. ==Description==
