Diagnosis. Males of Predatoroonops stani sp. nov. resemble those of Predatoroonops anna Brescovit, Rheims & Bonaldo, 2012, by the presence of the subdistal apophysis of chelicerae (sa) slightly curved dorsally at its distal end (Fig. 3; Brescovit et al. 2012b: fig. 19), but can be distinguished by the presence of basal condyle apophysis of chelicerae (cb) (Fig. 3), absent in P. anna (Brescovit et al. 2012b: fig. 19), large and long triangular subdistal furrow (sf) (Fig. 1A), narrow in P. anna (Brescovit et al. 2012b: figs 203–205), and the short, strongly curved retrolaterally, distal apophysis of chelicerae (da) (Fig. 3), that is elongated and narrow in P. anna (Brescovit et al. 2012b: fig. 19).
