This species from Christmas Island ( Australia, Indian Ocean) has a wider median septum in dorsal valve with stronger imprints of lophophore scars on its lateral sides than T. mawaliana sp. nov. In T. blochmanni , the brachial cavities are deeper and covered with very strong, thick angular spicules which were described “massive bouffantlike calcitic aggregations” by Logan et al. (2015, p. 230). The thin, irregular, fused spicules of T. mawaliana sp. nov. are quite different.

Remarks.? T. blochmanni in D’Hondt (1987) : the species is just cited without description and without illustration. This material must be revisited.
