Information: Idactus ellioti fasciculosus, was originally described from Tanzania by Aurivillius in 1903 as a separate species. However, until 2015, it was mistakenly referred to as Idactus usambaricus. According to the latest work by Teocchi in 2015, it is now considered only a subspecies of Idactus ellioti. This subspecies is commonly found in the savannas of East Africa.
[Idactus konso, described from Arba Minch by Quentin & Villiers in 1981, is very likely a synonym of I. usambaricus, which itself is considered a subspecies of I. ellioti Gahan 1890 (J. Sudre, in litteris).] Adlbauer 2008
