Type material. This species was described from the holotype female, which was not found in the MZUSP, where, according to the authors, it was supposed to be deposited.

Locality records: Brazil (Goiás) ( Fig. 22 ).

Comments: Scutops goianiensis is similar to S. robustus sp. nov. but differs from the latter by the short dorsal yellow stripe, not reaching the presutural region of the scutum (this stripe is long and reaching the anterior margin of scutum in S. robustus sp. nov.); and is similar to S. ipixunensis sp. nov. but can be differentiated from it by the yellow stripe on the scutum being tapered anteriorly (yellow stripe of the scutum truncate apically and rather quadrangular in S. ipixunensis sp. nov.).
