Remarks

The incomplete shells of Isotriphora sp. 1 are easily differentiated from those of the sympatric I. uncia sp. nov. by the presence of brown axial patches ( Fig. 6 View Fig A–B, E–F) and an earlier emergence of the median spiral cord, rapidly enlarging and reaching the same size of other cords ( Fig. 6C View Fig ). The most similar species to Isotriphora sp. 1 is “ Inella ” maculata Fernandes & Pimenta, 2019, from southeastern Brazil, which has a different protoconch. Complete shells of Isotriphora sp. 1 are required to formally describe this species.
