cultratus Humbert & Saussure, 1870: 175 [ Spirostreptus].

Brasilia. Unspecified series.

Saussure & Humbert (1872) gave a more detailed redescription, stating that the original description was based on three fragments of a ♂ collected by Natterer. No specimens found in the MHNG. The holotype is in the NHMW (Inventory number 2523/2532, Acquisition number 1866.I.92). The specimen was reviewed by Hoffman, who illustrated the head and left gonopod (Hoffman, 1968a). This specimen has two inventory numbers because it was also described as Alogostreptus nattereri Attems, 1950, making the latter a junior synonym of U. cultratus (Humbert & Saussure, 1870) .
