Scoturius dipterioides Perger & Rubio, 2018: 4 , figs 2, 3A, 3C, 4B, 5A (holotype, ♀, Bolivia, Santa Cruz (17°52’59.0”S 63°19’04.0”W), deposited in IBSI Ara 0713, not examined).

Remarks. Upon knowledge on the epigyne of Atelurius segmentatus ( Figs 47–48 , 68 ), type species of the genus, it is possible to propose the transfer of Scoturius dipterioides Perger & Rubio, 2018 to Atelurius Simon, 1901 , based on the morphology of the copulatory ducts. We suggest that the membranous portion (CD*) of copulatory ducts were not illustrated by the authors (compare with Fig. 48 : * asterisks to the membranous copulatory ducts).

Distribution. Only known from type locality in Bolivia [Santa Cruz]; see Perger & Rubio (2018) ( Fig. 77 ).

Natural history. According to Perger & Rubio (2018), this species was collected by beating tray and was suggested as a mimic of flies. Altitudinal distribution: 480 m a. s. l.
