Pachnoda acutipennis Kolbe, 1914

( Figs. 3d, e, f )

Distribution: ANG, DOC.

Distribution in Angola (Provinces): 1) LNO.

Historic records:

—Dundo (LNO) ( Gomes Alves 1973).

Material examined: Dundo (7º 22´S, 20º 50´E, 1470 m alt., 51) ( LNO), 2.V.1946, 1♀, Nº 651, Junta de Inves- tigações Coloniais (Entomologia), sub Pachnoda acutipennis Kolbe (Ruter det. 1968), IICT, MUHNAC .

Remarks. The species is known from Katanga Province in DOC ( Rigout 1989; Sakai & Nagai 1998) and was given for the north-eastern LNO Province of Angola by Gomes Alves (1973) based on a determination of the same specimen by Ruter in 1968 (see Fig. 3 d ). However, taking into account the elytral drawing pattern ( Fig. 3d ) of the humeral region the specimen seems closer to one species within the group of Pachnoda viridiflua Kraatz, 1900 , P. spinipennis Moser, 1914 , P. allardi Ruter, 1969 , P. dargei Rigout, 1987 , P. knirschi Rigout, 1984 and P. pygidiomaculata Beinhundner, 2013 . Nevertheless does not belong to P. spinipennis as the pygidium is dull and has six white spots behind the front edge and two near the apical edge ( Moser 1914b), nor to P. allardi do to its larger length (19 mm vs 15–15.5 mm), different pygidial colour pattern, among other characters, nor to P. knirschi by the presence of four white dots on the upper green-blackish part of pygidium (none in P. knirschi ) (cf. Fig. 13 i vs PII Fig. 6f in Beinhundner 2013), nor to P. dargei by the orange tibia (black in dargei ) and a different pygidial pattern of white dots (cf. Fig. 3f vs Fig. 4f in Beinhundner 2013), nor even to P. pygidiomaculata by the absence of metasternum transverse white stripes and the presence of metatibial denticle (cf. Fig. 3e vs Fig. 5b in Beinhundner 2013). It could belong to P. viridiflua by the same general elytral colour pattern, the pygidium colour and the white spots pattern in the frontal half of this structure (e.g. see description of P. schultzei = P. viridiflua in Preiss 1933 ). However, without a male to check the genitalia it is with some caution and based again on the Ruter’s identification that we keep the species P. acutipennis for the Angolan fauna. Biological and ecological data are not available for this species.
