SJO was collected near Funge, Cameroon in 2010, 2011 and 2013 during the "Stofmania" expeditions, and found another geographic locality where the blue form, first found in Loe, could be found.
In 1989 Horst Gressens returned from a trip to Cameroon to the Netherlands and entered a pair of SJO into the KFN show only to be told "these are not SJO, the color is completely wrong" and explained they were what he found in Loe, Cameroon. Thus from that day on we knew there was at least one other morphotype for SJO, previously known.
