DIAGNOSIS. — Rounded anterior margin, S2 transglabellar, S3 and S4 short; palpebral lobe short, from S1 to S3; anterior and posterior section of facial suture moderately to strongly divergent; thorax with 19-21 segments; pleural spines progressively directed more strongly backwards, hindmost pairs of pleural spines increase in length, ending behind pygidial margin; pygidium small, subcircular to quadrat (based on Whittington et al. 1997; Fletcher et al. 2005, with modifications). REMARKS The genus Paradoxides Brongniart, 1822, and the family Paradoxididae Hawle & Corda, 1847, need comprehensive revision, as pointed out by e.g., Sdzuy (1967), Geyer (1998), Geyer & Landing (2001), Kim et al.
