Remarks: The species was based on an unknown number of specimens from Arizona and Texas ( Casey, 1893: 530). The senior author has examined a male syntype labelled “Williams Ariz” / “TYPE USNM 48161” / “desertorum” (handwritten). As its aedeagal characters have not yet been published, respective illustrations are given here ( Figs 13, 14 ). An examined male syntype of Scaphisoma dakotanum Fall, 1910 , originally spelled dakotana, labelled “Wickham, Bismarck, N. Dak.” / “dakotana TYPE” / “M.C.Z. Type 24119” / “H.C.Fall collection” / “ Scaphisoma dakotana Fall ” is found conspecific with S. desertorum . It is here designated as lectotype, and bears respective label, dated 1987.

Hence, Scaphisoma dakotanum Fall, 1910 , syn. nov. = S. desertorum Casey, 1893 .

This species is reported from Arizona, North Dakota and Texas, the vouchers from Texas were not examined.
