Historic records:

—Dundo (LNO) (Gomes Alves 1959 and Ferreira 1965 sub Pachnoda nachtigali var. pseudomarginata Burgeon).

Material examined: Angola, 1 ♂, Nº 1907 (blue label), nº 122 (white label), Monteiro leg., old collection, box nº XIV-83, MZUC; Dundo (7º 22´S, 20º 50´E, 1470 m alt., 51) (LNO), -. X.1948, 1 ♂, Nº 2130, Junta de Investiga- ções Coloniais (Entomologia), IICT, MUHNAC.

Remarks. The species is polytypic, but the number of valid subspecies remains controversial. Marais & Holm (1992), Krajcik (2008a) and Schoolmeesters (2018) recognized five subspecies in Africa, including the nominal one. However, Beinhundner (2017a) recognized also Pachnoda orphanula pseudomarginata Burgeon, 1932 as a good subspecies, which is considered a synonym of P. orphanula nachtigali by the former authors. The subspecies was recorded for northeastern Angola by Gomes Alves (1959). The adult male specimens of MZUC and MUHNAC fit well this species description, including the parameres conformation (Figs. 4h, i, 5a). The MUHNAC specimen was collected by light trapping. Biological and ecological data are not available for this subspecies.
