Material examined: Angola, 1 ♂, Nº 1907 (blue label), nº 32 (white label), Welwitsch leg., old collection, box nº VI-75, MZUC ; Angola, 1 ♀, Nº 1907 (blue label), nº 33 (white label), old collection, box nº IX-78, MZUC .

Remarks. For long time, this species was considered a synonym of D. micans (Drury, 1773) (e.g. Lekkerkerk & Krikken 1986; Marais &Holm 1992; Krajcik 2008a), but recently De Palm & Frantz (2011) clarified the true status of D. johnstoni , elevating it to a valid species. The localities recorded for Angola suggested that it seems to be widespread in the territory. The larva of the third instar was described by Carl & Kühbander (1993) under the name D. micans . A synthesis of ecological data were provided by De Palm & Frantz (2011).
