How to Distinguish from Similar Species: Several other Lepidozona species have distinct longitudinal ridges between the pits on the central areas of the plates.

Biology/Natural History: This species is not often seen.

Rocks

Geographical Range: Southern Alaska to northern Mexico

The dorsal surface of the mantle has overlapping scales, and there are spicules along the margin. The body length is less than half the width. The lateral areas of plates 2-7 are not conspicuously raised with pronounced tubercles, but they do have hemispherical or nearly globular nodules. The central areas of plates 2-7 have longitudinal rows of shallow pits but the longitudinal ridges between the rows of pits are only faint.
