Remarks. Oxytelus congoensis ( Fagel, 1960) becomes a junior secondary homonym of Oxytelus congoensis Fauvel, 1903 , but also seems to be a junior synonym of Anisopsis guineensis , therefore no replacement name is provided now, pending further study. Anisopsis guineensis was described based on an unspecified number of specimens, out of which a female ( Fig. 6 ) is in the author’s collection (FMNH), while further two female exemplars remain in Silvestri’s collection. Only one of them has Bernhauer’s label, this specimen ( Figs. 4–5 ) is considered as a syntype. These female specimens appear to be within the possible variation range of the species previously known as Paranisopsis congoensis (holotype on Fig. 7 ). Primary types of both nominal taxa were studied and compared with available illustrations. Only more material (with a male) from the original type locality of Anisopsis guineensis ( Guinea) could absolutely confirm this synonymy.

A further note is necessary about a confusing figure in FAGEL (1960): the primary type of Paranisopsis congoensis is shown on Fig. 30 ; Fig. 61 might be another specimen of the same species. It is not explained in the text why two different figures are provided, but this might be also because of the range of variation experienced in this species.
