A new species of the genus Bantodemus is described (B. lajumaiensis sp. nov.) from the surroundings of the Lajuma Research Centre (Limpopo Province, South Africa). This discovery enforced the revision of some crucial morphological features used for species delimitation within the lucidus species-group. As a result a new identification key is provided for this species-group. Furthermore, the male morphology of Bantodemus montanus (lethaeus species-group) is described for the first time based on the material collected in the Lotheni Nature Reserve (KwaZulu-Natal, South Africa).
