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.

A. R. Palmer and L. N. Repina 1993Nevadiidae with glabella slightly tapered forward. Ocular lobes small, posterior tips about opposite SI or anterior part of Li. Width of interocular area equal to or greater than that of extraocular area. Thorax of 17 or 18 segments, maintaining width or widening slightly backward to eighth segment, then tapering posteriorly; posterior segment may be fused with anterior part of simple pygidium. Pleural spines short; pleural regions only slightly wider than axis.
L. E. Babcock and J. S. Peel 2007Glabella slightly tapering forward; ocular lobe relatively small, posterior opposite L1; interocular area narrower than extraocular area; genal spine short, rarely extending posteriorly beyond the first thoracic segment. Thorax with 17-18 segments; posterior segment may be fused with anterior part of simple pygidium; pleural spines short (exsag.), slender.
