Two new Thaumatoconcha Kornicker and Sohn, 1976a species, T. dandani n. sp. and T. quasiporosa n. sp., have been described in the present paper. Both species have been collected during two expeditions to the Southern Ocean and are found in the deep sea. The first species is most closely related to T. caraionae Kornicker and Sohn, 1976a, but it has a very specific appearance of copulatory organ, anterior part being covered in small spines. The second species is most closely related to T. porosa Kornicker, 1985, and they differ in the carapace shape and morphology, while they have almost identical appearance of the male copulatory organ. A list of Thaumatocyprididae species and a key to the species of Thaumatoconcha are also presented in this paper.
