Richards , Oxford University Expedition K.B.G. , NHM 1930.1164.3491, examined) Sparianthina rufescens : Jäger et al. 2009: 133 , figs 71−73, 79. Note. While studying additional material of S. rufescens I observed that females of this species do not have the longtoothed palpal claw which is characteristic for the genus and subfamily. Thus, it is here considered incertae sedis until further studies are carried out and the placement of the species can be determined.
