Resumo: 	This study presents four morphological criteria based on the shell, determined under a stereomicroscope, allowing the identification of the Calyptraeidae’s post larvae in Calyptraea chinensis and Crepidula fornicata from a 0.7mm size. The septum shape in C. chinensis is spiraled while in C. fornicata it is perpendicular to the longitudinal axis of the shell (beginning of the lodge’s formation), which constitutes the most reliable criterion when trying to discriminate between the species. C. chinensis shells coloration appears homogeneous and concentric whereas colored spots are observed on C. fornicata shells. Calyptraea chinensis shell shape is circular while Crepidula fornicata shell shape is oval. Lastly the apex appears centered in C. chinensis and off-centred in C. fornicata.
