Plagiochilus angustatus (Westwood, 1873)

( Figs. 12g, h )

Distribution: ANG, BEN, CAM, GAB, CON, DOC, SLN, TAN, UGA, ZAM, ZIM.

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

Historic records:

—Quango (=Cuango) (LNO) ( Quedenfeldt 1884 sub Anoplocarpus marginatus Quedenfeldt ).

— Angola (without locality) ( Antoine 2010).

Material examined: Carima (Cacuso–Pungandongo) (09º 35´00´´ S, 15º 42´01´´ E, 1117 m alt., 130) ( MAL), 20.XI.2017, 1♂, DO, A. Serrano & R. Capela leg., ASC .

Remarks. The species was first described from SLN and UGA and given later for other countries, including Angola (e.g. Antoine 2010). Basilewsky (1956) refered for Aspilus gambiensis Burmeister, 1842 that “Selon BOURGOIN, Anoplocarpus marginatus QUEDENFELDT , d’Angola, serait la même espèce”. However, there are not references to this synonymy in any African Catalogue. The adult specimen of Carima was collected feeding on the basis of tomentose leafs of spontaneous herbaceous plants ( Fig. 12h ) in a secondary open forest ( Fig. 10a ). See also Amaurina spoliata remarks. Biological and ecological data are not available for the species, but see the general comments on the genus Coenochilus . It is a new species record for the Malanje Province.
