Diagnosis.

Capitulum with fully or partially calcified plates; peducle with calcareous or phosphorus scales. According to Gale (2016), the Scalpellidae have a maximum of 14 plates i.e. carina, rostrum, paired scuta, terga, upper latera, carinolatera, rostrolatera and inferior median latera; and rarely 13 plates, due to secondary loss of the rostrum.
