  Revision of the Elusive Harvestmen Genus Discocyrtulus Roewer, 1927 (Opiliones: Laniatores: Gonyleptidae): Investigating the Presumed Northeastern Brazilian Discocyrtus-Like Relatives ABSTRACT A maximum parsimony analysis based on morphological characters (23 taxa; 98 characters; 1951 scorings) was conducted to test the monophyly of Discocyrtulus Roewer, 1927, and to assess its phylogenetic relationships within Gonyleptidae. The results recover the species currently assigned to Discocyrtulus as phylogenetically distant from Pachylinae sensu stricto and nested instead within Discocyrtus sensu stricto +, forming a clade together with Discocyrtus moraesianus Mello-Leitão, 1923. Accordingly, Discocyrtulus is removed from Pachylinae Sørensen, 1884, and left without subfamilial assignment. As a result, Discocyrtulus now comprises Discocyrtulus crenulatus (Roewer, 1913) comb. nov. , Discocyrtulus marginalis Roewer, 1929, and Discocyrtulus moraesianus (Mello-Leitão, 1923) comb. ...
