macrourus Humbert & Saussure, 1870: 176 [ Spirostreptus].

Brasilia. Unspecified series.

Saussure & Humbert (1872) gave a more detailed redescription of the ♂ only. No specimens found in the MHNG. Although there is a single type specimen listed in the NHMW Acquisition Register (Acquisition number 1866.I.104), the specimen is apparently lost. Hoffman (1999: 36) considered that the original placement of this species in the genus Spirostreptus instead of Spirobolus was probably a lapsus calami.
