Figure 6B View FIGURE 6

Pattern description. Bright yellow-orange fluorescence. Body and first spire whorl show a “tent” pattern of solid, “false” triangles. Generally, one edge of the triangle is aligned to axis and the third point facing sinistrally. Location of triangles apparently random. Triangles occasionally overlap slightly, varying in size, but all are relatively small. Remaining whorls/protoconch show a solid yellow fluorescence.

Comment. Nannamoria strophodon (McCoy, 1876) is the closest match of the Australian tertiary species known in this genus and has been recorded from the Murbko Marl. However, this species is described as very morphologically variable, and it is the opinion of the authors that it likely comprises several species. For example, N. malonei Hawke, 2021 and N. gnotuki Hawke, 2021 were synonymised with N. strophodon by Daragh (2024), despite having distinct body shapes and differences in the number, size and shape of shoul- der nodules. The specimens studied in this paper are distinctly different from N. gnotuki as described by Hawke (2021) and cannot be reasonably identified as the same species, i.e., N. strophodon . The patterns found through fluorescence here do not match those described from residual patterns of N. strophodon , which Darragh (1989) says to have thin, close set wavy lines. Thus, future comparison with previously identified specimens of N. strophodon is recommended to consider separation of the species.
