( Fig. 12f )

Distribution: ANG, CAM, DOC, EQG, GAB, GAM, KEN, MOZ, NAB, RCI, RSA, SEN, SLN, TAN, TOG, ZIM.

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

Historic records:

—Quango (=Cuango) (LNO) ( Quedenfeldt 1884 and Ferreira 1965);

—Malange (MAL) ( Schein 1954a).

New localities reported: Cahama (20 km NE) (coord. not available, 1315 m alt., 399) ( CNN), 8.XII.2013, 1♂, P. Schüle leg., PMC (P. Malec, personal communication) .

Material examined: Cacuso (9º 25´28.03´´S, 15º 44´37.63´´ E, 1078m alt., 112) ( MAL), 16–18.XI.2017, 1♂, DO, A. Serrano leg., ASC; Quitota (9º 37´32.39´´ S, 15º 25´22.57´´ E, 898m alt., 129) ( MAL), 20.XI.2017, 1♀, LT, A. Serrano & R. Capela leg., ASC .

Remarks. It is the type species of a group with its own name ( C. ventricosus group sensu Schein 1954a). The Cacuso adult specimen was found on the ground during night near public lights. Like some C. procerus specimens, the Cacuso specimen had phoretic acarina on some parts of the body (e.g. legs). The Quitota adult specimen was collected by LT (e.g. Fig. 1c ) in an open secondary forest. Joly (2018) provided biodiversity information (abundance, habitat preference) on this species for Ghana. Other biological and ecological data are not available for the species, but see also general comments in Schein (1954a) and the remarks under the genus Coenochilus . It is a new species record for the Cunene Province.
