The other characters are very variable and unavailable for further splitting of the groups, being sometimes found in species of the A. pallidicornis group (e.g., a long apicoventral bristle on the fore tibia). Notes The Amblypsilopus stuckenbergi group is endemic to Madagascar . The following species belong to this group: A. analamazaotra , A. andasibensis , A. fianarantsoa , A. freidbergi , A. leonidi , A. olgae and A . stuckenbergi .
