In addition females of N. africana Schmidt, 1944, N. aurantiaca (Lieftinck, 1938) and N. hiroakii Sasamoto, 2007 are described and the morphology and variability of a number of additional species is discussed. Diagnostic characters of the available genders are illustrated, habitat conditions are given and their affinities are discussed. Live photos of selected species are presented. Keys to the males of all Nososticta species known from New Guinea and the Solomon Islands, and to the described females from this region are included. Nososticta lorentzi Lieftinck, 1938 is considered a synonym of N. nigrifrons (Ris, 1913) (syn. nov.).
