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. Y. Ivantsov 1999||The dorsal side of the exoskeleton is tripartite. Cephalon bears large eyes, situated near its posterior margin, and segmented librigenae, facial sutures not connected with the eyes. Thorax is reduced and composed of four segments with incomplete pleurae. Pygidium is longer than the cephalon and thorax combined, and consists of at least 24 segments. The first two pygidial segments lack tergites, the tergites of the second to seventh segments are bordered by open sutures. Phytophilaspis differs from all of other Conciliterga Hou & Bergström, 1997 by the absence of rostral plate, posterior position of eyes and large size of the pygidium.|
