"Tecticrater" is a genus of very small deepwater limpets, marine gastropod molluscs in the family Lepetellidae.

Distribution

Species in this genus are endemic to New Zealand.

Habitat

Members of the genus are found at depths of between 50 and 800 m.

Description

These small limpets have their shell apex directed posteriorly, and have rhipidoglossate dentition (that is, with central, lateral, and marginal teeth). The shells are small, with laterally compressed sides.

The radula formula is 2+1+1+1+2. Compared with "Tectisumen", the central tooth is narrower, the lateral considerably larger and the outer marginal reduced to a formless plate.
