A study was conducted to reevaluate the phylogenetic position of Discocyrtus catharinensis (Mello-Leitão, 1923) in the family Gonyleptidae Sundevall, 1833. Based on a maximum parsimony cladistic analysis of 22 terminal taxa and 92 morphologic characters (1766 scorings), (1) the genus Parasadocus Mello-Leitão, 1927 is restored from the synonym list of Discocyrtus Holmberg, 1878, and transferred from Pachylinae Sørensen, 1884 to Roeweriinae Carvalho & Kury, 2018, and (2) the specific combination Parasadocus catharinensis (Mello-Leitão, 1923) is also restored. P. catharinensis comb. rest. is here redescribed, and its geographical record of “Itatiaia” is contested. Finally, a lectotype is proposed here to solve questions about the type series of “Lycomedicus brasiliensis Soares & Soares 1949” (junior synonym of P. catharinensis comb. rest.).
