A cladistic analysis of the Tegulinae (Turbinidae) is presented using 132 morphological characters and 41 taxa. Tegulinae is recovered and is sister to Prisogaster niger (Prisogasterinae) within the family Turbinidae. This scenario, with Tegulinae as a subfamily within Turbinidae, corroborates with the most molecular analyses. Tegulinae comprises >40 extant species, belonging to eight genera. Morphological studies have not resolved the placement of Tegulinae within Trochoidea sufficiently, and the systematic positions of the genera have never been investigated as a primary objective. The present morphology‐based analysis of genus‐level relationships within Tegulinae provides a robust, phylogenetic diagnosis of each group, rooted on a firm hypothesis of evolutionary relationships. An additional search was performed to include the tegulines Omphalius nigerrimus and Carolesia blakei terminals using unweighted and implied weighting. Our morphological data provide a solid foundation for ensuing systematic research on Tegulinae, as well as Trochoidea, and evidence facilitating the diagnosis of generic and suprageneric groups.
