Specimens examined.

Edea, Sanaga waterfall, Buesgen 439 (M); Sanaga waterfall, Buesgen s.n. (B, U).

Habitat.

River rapids and waterfalls in tropical rain forests.

Distribution.

Angola, Cameroon (Fig. 25 View Figures 20–25 ), Democratic Republic of Congo.

Conservation status in Cameroon.

Leiothylax quangensis   has been assessed for the IUCN Red List as Endangered ( Ghogue 2010m). The taxon is known from one locality, Edea waterfalls. The area of occupancy and extent of occurrence are both estimated at 2 km2 each. The hydropower dam at Edea will certainly impact the quality of the habitat of the species. L. quangensis   is here reassessed as Critically Endangered. IUCN Red List Category: Critically Endangered CRB1+2ab (ii, iii).
