Tricholeiochiton larvae (Fig. 19) Material examined. ANGOLA: 1 cased larva, [CAW 740H], Moxico Province, Cuanavale River, Site 1—upstream of source lake (closer to lake), aquatic vegetation, handnet, -13.0882, 18.89298, 30/x/2016, I.S. Ferreira; 1 cased larva, [CAW 755M], Moxico Province, Cuanavale River, Site 3—upstream of source lake (further from lake), aquatic vegetation, handnet, -13.0935, 18.89627, 31/x/2016, I.S. Ferreira. Remarks. The larvae clearly key to this genus, but collection of adults or pharate adults is required for confirmation of identity. Larvae of Tricholeiochiton generally live among aquatic macrophytes and, like other members of the subfamily Hydroptilinae, feed on filamentous green algae according to Marshall (1979).
