The type material of Sarax buxtoni (Gravely 1915) cannot be located and has to be considered as lost. Therefore, a description compiled from a population in Singapore is provided, including morphological and taxonomical details presented for the first time. Comparisons with closely related species are supplied. Furthermore, we describe the occurrence of parthenogenesis in a population of S. buxtoni, representing the first case of asexual reproduction in a member of the genus Sarax Simon 1892.
