Taxonomic notes. We examined the type material of Sadocus brasiliensis and its external and penial morphology did not match that of other Chilean species of the genus. Based on its type locality, we examined other Brazilian Pachylinae genera and found striking similarities between S. brasiliensis and D. catharinensis . We examined detailed pictures of the type material kindly shared by Rafael N. Carvalho and additional material from the MZSP collection. Those species are the same, and we propose that S. brasiliensis is the junior synonym of D. catharinensis . Many Discocyrtus spp. have been transferred to revalidated genera or newly created subfamilies, such as Roeweriinae ( Carvalho and Kury 2018 ) or Neopachylinae ( Carvalho and Kury 2021 ). Indeed, the penial features of D. catharinensis (Fig. 15K, L) resembles those of that subfamily, which is corroborated in the present analysis: D. catharinensis is the sister species of R. bittencourti . Based on male genitalia and leg IV (see Carvalho and Kury 2018 ), D. catharinensis seems to belong to Discocyrtanus Roewer, 1929. However, because there is an ongoing study revising Discocyrtus conducted by Rafael N. Carvalho (MNRJ) and taking into account that it will have serious taxonomic consequences, we opted to propose only the synonymy of S. brasiliensis with D. catharinensis .
