Permian rocks from the Indonesian island of Timor contain an abundant and diverse pelmatozoan echinoderm fauna that was extensively monographed in the first half of the twentieth century. Recent collections have produced specimens of Corrugatoblastus savilli, n. gen. n. sp., the first new genus of blastoid described from Timor in 70 years. Corrugatoblastus savilli is a ridged and furrowed, conical, fissiculate blastoid with a highly unusual thecal morphology mimicking a small, solitary, rugose coral. We have placed C. savilli in the Family Codasteridae, although it has several morphological features that are unique when compared to other genera in the family and to other blastoid genera regardless of familial assignment.
