Dischista rufa (De Geer, 1778)

( Fig. 2h )

Distribution: ANG, BOW, MOZ, NAB, RSA, ZIM.

Distribution in Angola (Provinces): 1)?; 2) HUI.

Historic records:

— Angola (without locality) ( Harold 1879 sub Pachnoda rufa var. frenata Burmeister );

— Angola (without locality) ( Ferreira 1965 sub Pachnoda rufa var. frenata Burmeister ).

Material examined: Huilla (=Lubango) (14º 55´S, 13º 30´E, 1750 m alt., 336) ( HUI), 1 ♂, Nº 1846 (blue la- bel), nº104 (white label), old collection, box VI-75, Anchieta leg., MZUC; Angola, 2 exs, Nº 1907 (blue label), old collection, box nº XIV-83, sub Cetonia rufa De Geer , MZUC.

Remarks. The species is misinterpreted sometimes with D. impunctata (see Remarks under this species). Beinhundner (2017a) did not include Angola in its distribution. This species is easily differentiated by the parameres conformation, the pygidial spot and the mesometasternal process shape (see Holm & Marais 1992, p. 224–225). Biological and ecological data on D. rufa were provided by Holm & Marais (1992). Malec & Šípek (2017) included this species, jointly with D. cincta , in their group 4 (species requiring a special feeding substrate composition).
