| A. R. Palmer and L. N. Repina 1993 | Judomiidae with glabella barely touching border or with preglabellar field present. 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.
