Abstract:
Paradiscocyrtus neglectus Mello-Leitão, 1927 is here redescribed and for the first time illustrated. A neotype is proposed to clarify the taxonomic status of this species and to differentiate it from the other two species of Paradiscocyrtus and related genera (e.g., Discocyrtus). Two junior synonyms of this species, currently allocated in Discocyrtus Holmberg, 1876 are here detected. This harvestman is endemic from areas above 2000 meters of altitude, occurring in the Campos Rupestres montane savannas terrestrial eco-region in the states of Minas Gerais and Rio de Janeiro, Brazil. This species is characterized by the powerful retrodorsal apophysis of the coxa IV, the unique armature of dorsal scutum, trochanter IV, and femur IV.
