Material. AndaDeVos (2).
Characterization. Shell minute, H 0.7 mm, W 0.7 mm; DN 0.09 mm; P terminated by well defined, rounded varix at 1.1. whorls; T whorls with a sharp keel and covered by fine, axially arranged granules; body whorl with 3 sharp spiral ribs; base broad and flat; umbilicus narrow, umbilical ridge weakly granulated.
Distribution. Reported from Bohol, Philippines, 38 m depth, Wakasa Bay, Japan, 40–161 m depth ( Higo et al. 1999), and Hong Kong, Pakistan, Sri Lanka, Malaysia and Thailand ( Poppe et al. 2006).
Remarks. Minolia holdsworthana (G. & H. Nevill, 1871) was synonymized with M. charmosyne Melvill, 1918 by Herbert (1989). These two species were synonymized with Margarita musiva Gould, 1861 and attributed to Pseudominolia by Poppe et al. (2006). The synonymy is considered here to be justified, based on the strong conchological similarity, but the allocation to Pseudominolia by Poppe et al. (2006) is superfluous, because the species is already allocated to Conotalopia , according to Higo et al. (1999). The allocation to Conotalopia is also preferred here, because C. musiva shares similarities with other species of Conotalopia , such as a relatively high spire and strong spiral ribs. Furthermore, the apical beak of the protoconch, which is a diagnostic feature for Pseudominolia ( Herbert 1992) , is very poorly developed in the studied material. Unfortunately, there are no SEM pictures of the protoconch of type material of Pseudominolia musiva ( Gould, 1861) or the synonymized taxa available to verify the absence of the apical beak in the species.
