Distribution elsewhere. Not reported.

Remarks. Species described from Brazil. The measurements are similar to those of the original description and to those of the redescription by Demite et al. (2016). Our observation of the holotype showed that seta r3 is placed on the dorsal shield instead of on the insterscutal membrane, as mentioned in the original description of the species.
