REMARKS
The holotype (AMS-C.19544) (Fig. 23A, B) is rather damaged, especially on the aperture (it has also suffered partial corrosion from the Byne’s disease). This species has rarely been reported in the literature (e.g. Middelfart et al. 2020: 171, fig. 8C) and more often under other names (e.g. Kay 1979: 78, pl. 27, fig. D, as Parashiela beetsi, fide Hasegawa 2006b:109; Fukuda 1993: 40, pl. 13, fig. 188, as Parashiela ambulata; Ekawa, 1993, as Parashiela sp., fide Hasegawa 2006b: 109).
