2015 Thecidellina maxilla: Bitner, fig. 5A–E.

The adult shell is larger. Brachial cavities have peculiar single canopying spicules that are very massive in the anterior part of the canopies and much thinner in their posterior part ( Cooper 1954, pl. 80, figs. 10–13; Logan, 2008, figs. 6–17). In the smaller shell of T. mawaliana sp. nov. the canopies are made of very thin, fragile spicules all fused together.
