Material examined: Angola, 2 ♂, Nº 1907 (blue labels), nº 146a (white labels) , 1 ♀, Nº 1907 (blue label), nº 147a (white label), 1 ♂, Nº 1907 (blue label), nº 148a (white label), old collection, box nº IX-78, MZUC; Dundo (7º 22´S, 20º 50´E, 1470 m alt., 51) ( LNO), -. III.1949 , 5 ♂, 4 ♀, Nº 2132, 2 ♀, Nº 2151, Junta de Investigações Coloniais (Entomologia), IICT, MUHNAC .

Remarks. The status of this taxon is very controversial. Its validity was established by Antoine (2002a), a criterion followed by Beinhundner (2017a). However, Krajcik (2008a) as well as Schoolmeesters (2018) keep it as a synonym of G. lurida Janson, 1877 [the name lucida used by Krajcik (2008a) is a misspelling of lurida , since Janson (1877b) did not describe any taxon named lucida]. Gnathocera cruda gracilis was described based on one specimen from Angola, but Janson (1877b) referred that “there are also specimens in Mr. Higgins’s collection found by Monteiro, at Bembe”, a municipality within the Uíge Province. The adult specimens of IICT were collected by light (registered information) probably at the same time of G. trivittata ardoini (see remarks under this taxon). Ecological data are not available for this subspecies.
