Type material. Holotype of Scotobius akidioides bicostatus ( Fig. 11 ): [Chubut/ Esquel I-1941] [Paratype] [Holotypus / akidioides ssp. / bicostatus nov./ det. H. Kulzer 1955] ( NHMB). Note: the label of holotypus lacks generic name.

Holotype of Scotobius freudei ( Fig. 12 ): [Rio Negro/ El Bolsón/ IX-56 (pro 1956) K. (pro Kovacs)] [ Scotobius / freudei / mihi] [Holotypus / Scotobius / freudei / Marcuzzi, 1977] [Museo Genova/ coll. G. M a r c u z z i / (acquisto 2000)] ( MSNG).

Discussion. The type specimens of both nominal species present the same characters given by Kulzer (1955) in his description of Scotobius akidioides bicostatus and by Marcuzzi (1977) for S. freudei ( Figs. 11–12 ): pronotum arched with lateral margins raised forming a slightly marked groove with the disc, posterior margin wider than anterior margin, anterior angles rounded, posterior angles obtuse; each elytron with one carinae closer to lateral margin than suture, with a strong declivity between this carina and the lateral margin carina-shape.
