Forrestopius larryi Gauld & Sithole, 2002: 157 . Comments. This species was originally described under Forrestopius . However, it shows many features that disagree with the generic diagnosis, such as the palpal formula 4:3 (vs. 5: 4 in Forrestopius ); similar palpal formula can be also found in Leurus xalifer Gauld & Sithole, 2002 . Leurus larryi has the protibial spur antero-dorsally with comb and postero-dorsally with velum (vs. protibial spur antero-dorsally without comb and without velum and postero-dorsally with comb in Forrestopius ). Additionally, the Forrestopius species that have two mandibular teeth have 14–20 flagellomeres and the species with three teeth have between 26–30 flagellomeres, while L. larryi has two mandibular teeth and 30–32 flagellomeres.
