Male holotype from Espiritu, José Ballivián, Beni, Bolivia (Staatliches Museum für Naturkunde, Karlsruhe 13318, not examined) .

The original description left no doubt that this species belongs to Grismadox due to the presence of a fovea, second pair of abdominal setae spiniform, the slightly constricted abdomen and the screw-like embolus, devoid of RTP.
