Comparison with Thecidellina insolita Hoffmann et al., 2009

In T. insolita the cardinal process has a wider median spur than in T. mawaliana sp. nov. The calcitic pole is not connected to the valve floor in T. insolita whereas it is strongly fused with the valve floor in T. mawaliana sp. nov. In T. insolita the brachial cavities have single massive canopying spicules and marsupial notches are larger and more quadrangular.
