Lepidopleuridae

Belongs within: Neoloricata.

The Lepidopleuridae are a group of small chitons in which the articulamentum is poorly developed (Smith 1960).

Characters (from Smith 1960): Relatively small (less than 5 cm long); valves generally sculptured with granules closely set in lines or quincunx; valve coverage complete; girdle narrow, minutely spiculose or scaly; insertion plates lacking, or if present, weak and unslit; articulamentum layer usually consisting only of weakly developed sutural laminae in valves ii to viii. Gills short, posterior.
