Trilobita - Redlichiida - Judomiidae
It was assigned to Judomiidae by Palmer and Repina (1993) and Whittington et al. (1997); and to Olenellida by Sepkoski (2002).
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Border well defined with sagittal length greater than that of preglabellar field (when present) and about equal to or slightly greater than sagittal length of occipital ring. Posterior tips of ocular lobes opposite occipital ring. Thorax with 15 to 17 thoracic segments; pleural furrows weak or absent. Opisthotliorax not developed. Pleural spines long; trans- verse length of thoracic pleurae more than twice width of axis. Pygidium elongate, with posterior median notch; last two thoracic segments may be fused with pygidium in axial region only.|
