Gnathocera trivittata ardoini Ruter, 1967

( Figs. 22g, h )

Distribution: ANG, BEN, CON, DOC, GAB.

Distribution in Angola (Provinces): 1) LNO; 2) HUA.

Historic records:

—Dundo (LNO) ( Gomes Alves 1959 and Ferreira 1965 sub Gnathocera trivittata transitiva Kolbe, 1919 );

—Dundo (LNO) ( Ruter 1967b);

—Quango Strom (von Mechow) Angola? (LNO?) ( Ruter 1967b).

Material examined: Dundo (7º 22´S, 20º 50´E, 1470 m alt., 51) ( LNO), -. III.1949, 17 ♂, 15 ♀, Nº 2132, 1♂, 1 ♀, Nº 2151, Junta de Investigações Coloniais (Entomologia), IICT, MUHNAC; Cambiote (Huambo) (coords not available) ( HUA), 19.III.1965, 1♂, 1♀, on corncob, E. Marçal leg., JPCC, MUHNAC .

Remarks. This subspecies was recorded for Angola (Dundo) before its description under the name Gnathocera trivittata transitiva ( Gomes Alves 1959) . The adult specimens of IICT were collected by light (registered information), probably at the same time of G. cruda gracilis (see remarks under this taxon). We found two adult specimens in JPCC from Huambo with information that they were collected on corncobs. Biological or ecological data are not available for this subspecies. It is a new species record for the Huambo Province.
