Abstract: Protochitonidae Ashby, 1925 is a family of small to medium sized chitons that includes a single fossil genus and two extant genera. Of the two extant genera, Deshayesiella Carpenter in Dall, 1879 contains 5 described species. Although most Deshayesiella species are known to be found in deep sea habitats (over 100 m), D. curvata (Carpenter in Pilsbry, 1892) is found from shallow waters (1-20 m). In this study, we provide details of microstructure of shell and radula characters using scanning electron microscopy and morphological features of D. curvata, and its partial sequence of mitochondrial DNA cox1 gene as DNA barcode sequence. In addition, we compare morphological differences of D. curvata from other congeneric species.
