Talopena maestratii Herbert 2024, sp. nov.

Talopena maestratii sp. nov. urn:lsid:zoobank.org:act: B3E16EEF-DA5E-415A-8C12-F51FBF6B38E9 Figs 39–43 Monilea cf. menkei – Héros et al. 2007: 209. Diagnosis Talopena maestratii sp. nov. is characterised by its relatively large and robust shell bearing crisp, evenly sized spiral cords with fine, close-set spiral microlirae in their intervals; cords undulant rather than beaded; parietal region with callus lobe at insertion of columella; thickened peri-umbilical band bears coarse pliculae and termination of umbilical funicle frequently yellow. Etymology Named for Philippe Maestrati (MNHN), in recognition of his enormous contribution to our knowledge of marine molluscan diversity, particularly in New Caledonia, through his many years of field work in the region, from Expédition Montrouzier (1993) to KOUMAC 2.3 (2019).
