154D7F18FFD1FFC2FC5DFA48FD805145.taxon	distribution	DISTRIBUTION. — Magellanic Region, from Chonchi, Chiloé Is., Chile in the Pacific Ocean, ranging between depths of 3.7 to 55 m, to off Mar del Plata, Argentina in the Atlantic Ocean, at a depth of 100 m. This distribution pattern is usual for Magellanic fauna, where species inhabiting shelf waters in the south reach the north following the cold Malvinas Current despite the apparently absence of free larvae (Carcelles 1944; Pastorino & Griffin 2019; Chiesa et al. 2024 and literature cited therein).	en	Sánchez, Noelia C., Aldea, Cristian, Pastorino, Guido (2025): The conoidean genus Belalora Powell, 1951 (Gastropoda, Mangeliidae) under the magnifying glass: an exclusive inhabitant of Magellanic waters.

154D7F18FFD1FFC2FC5DFA48FD805145.taxon	discussion	REMARKS Tryon (1884: 222, pl. 33 in error, pl. 32, fig. 18) considered Fusus sublutus Gould, 1849 with unknown locality in the genus Bela and commented that B. cunninghami is possibly a synonym (Tryon 1884: 222, pl. 34, fig. 75). In the same paragraph, he also indicated that this shell exhibits “ the peculiar appearance of the Magellanic molluscan fauna ”, including F. sublutus in this region without any clear proof. The holotype of F. sublutus housed at USNM 5684 and illustrated here (Fig. 4) show more similarities with a buccinoidean than a conoidean. We agree with WoRMS (2024) and considered it taxon inquirendum. Grant & Gale (1931: 531) in a general catalogue of Quaternary marine molluscs from California (USA) synonymized Pleurotoma cunninghami and Lora equatorialis (Dall, 1919) with Lora subluta (Gould, 1849), with no reason. There are two lots of Lora equatorialis Dall, 1919 in the USNM collection: USNM 97092 (illustrated here in Fig. 5 A-C) from Reina Adelaida archipelago in the Strait of Magellan and USNM 97070 (some of them illustrated here in Figure 5 D-I) from Manta, Ecuador, not included in Dall’s original description. As far as can be seen, both lots undoubtedly belong to two different species. McLean (1971 a: 712, fig. 1667) illustrated the Magellanic syntype and assigned the species to the genus Leucosyrinx Dall, 1889 with doubts. In a different work, he illustrated the radula of one specimen (McLean 1971 b: 120, fig. 38) from USNM 97070 (from Manta, Ecuador) and, this time, truly assigned it to Leucosyrinx. This radula dissected by McLean and the shells of the USNM 97070 identified by him as Leucosyrinx equatorialis are very different from the material here included in Belalora. In addition, Dall’s syntype (USNM 97092, Fig. 5 A-C) of Lora equatorialis is not a conoidean but a Buccinoidean of the genus Pareuthria Strebel, 1905 (probably P. atrata (E. A. Smith, 1881 )). Barnard (1963: 606) pointed out some similarities between Drillia spiralis Barnard, 1958 from Cape St. Blaize, South Africa, and Belalora thielei, however, he decided to maintain D. spiralis as a valid name. After observing a photograph of the holotype of D. spiralis (herein Fig. 4 G-I), we concluded that this is a different species with no relation with Belalora. Castellanos & Landoni (1993) mentioned that B. thielei would be a synonym of B. cunninghami. Both species have a similar shell with sympatric distribution. However, as far as it can be seen in the holotype, the only specimen available for comparison, the main difference appears to be the wider shell and lower spire of B. thielei. Forcelli (2000: 111, fig. 331) and Forcelli & Narosky (2015: 204, pl. 6, fig. 2) referred to Oenopota cunninghami and B. thielei as synonyms, although the specimen they illustrate does not correspond to either species.	en	Sánchez, Noelia C., Aldea, Cristian, Pastorino, Guido (2025): The conoidean genus Belalora Powell, 1951 (Gastropoda, Mangeliidae) under the magnifying glass: an exclusive inhabitant of Magellanic waters.
