The Trichoptera of the lower Kunene River were collected at irregular intervals from 1994 to 2012 by the first author. Samples were taken mainly at several localities on the Namibian side of the border downstream of the Ruacana hydroelectric power plant. Field work concentrated on adults, which were collected by light traps. Together with results of previous investigations a total of 41 species in 16 genera covering five families are now recorded from the river. About four species were found as immatures in the past, and were identified to generic level only. The first author has collected 27 species including nine undescribed ones: Catoxyethira kunenica sp. nov., Orthotrichia epupae sp. nov., O. vadalis sp. nov., O. kunenensis sp. nov., Ecnomus magnus sp. nov., E. quadrangulatus sp. nov., E. (Psychomyiellodes) statzneri sp. nov., E. (Psychomyiellodes) angonamus sp. nov. and Ceraclea (Pseudoleptocerus) lepidopterella sp. nov. Descriptions and illustrations of the genitalia of the new species are provided. Two species were synonymized: Oecetis kunenensis Barnard, 1934 = Oectis reticulatella Kimmins, 1957, syn. nov. and Oecetis tripunctata (Fabricius, 1793) = Oecetis ovamboensis Barnard, 1934, syn. nov.
