Gnathocera angolensis angolensis ( Westwood, 1854)

( Fig. 21i )

Distribution: ANG, CAM, CON, DOC, KEN, RCA, UGA.

Distribution in Angola (Provinces): 1) MAL, LNO.

Historic records:

— Angola (without locality) ( Westwood 1854);

—Malange (= Malanje) (MAL) ( Quedenfeldt 1884 sub Gnathocera trivialis Gerst. );

— Angola (without locality) ( Basilewsky 1949);

—Muita/Luembe (LNO) ( Gomes Alves 1959, Ferreira 1965).

Material examined: Angola, 1 ♂, Nº 1907 (blue label), nº 137 (white label), old collection, box nº IX-78, MZUC; Muita (Luembe) (7º 48´S, 21º 26´E, 700 m alt., 69) ( LNO), 6.VI.1948 , 6 ♂, Nº 2125, 5.VI.1948, 2 ♂, 1 ♀, Nº 2126, Junta de Investigações Coloniais , IICT, MUNHAC .

Remarks. A species described originally from Angola, but with a wider distribution throughout Central, western and eastern Africa ( Ferreira 1965; Allard 1991; Rohwedder 2011; Beinhundner 2017a; Schoolmeesters 2018). The IICT adult specimens of this species and of Gnathocera trivialis Gerstaecker, 1883 were found in the same date and site in Muita (syntopic) (see also the remarks under G. trivialis ). Although common ( Allard 1991), little is known about its biology and ecology.
