ResumoThe adult of Scalpellopsis striatociliata and the ontogeny of its capitular and peduncular plates are described. During ontogeny, S. striatociliata develops the carino-lateral (CL) and inframedian (L2) plates heterochronously after some peduncular plates (cl), which is unique. The position of Scalpellopsis as sister-group of the other scalpellids is reaffirmed. The Scalpellidae have diverse peduncular plate patterns, with the 8-plated pattern being ancestral and the most widespread among the genera. The peduncular plate patterns of several species of Scalpellidae are presented.
