The new genus and species of Polyancistrini katydids Tainacanthus ferox gen. nov., sp. nov. is described from specimens collected in the highest mountains of the Dominican Republic, island of Hispaniola. This is the third genus of Polyancistrini known from Hispaniola and the seventh genus of the tribe. Tainacanthus is distinctive due to the unique architecture of its pronotum, which is a large and bulbous shield with an extended metazona that covers and protects the stridulatory apparatus surrounded by a relatively small number of large and sharp spines. Additionally, all legs are armed with larger and more robust spines than those of Polyancistrus Audinet-Serville, 1831, its most likely closest relative. Tainacanthus inhabits the highest mountains of the Dominican Cordillera Central at over 2,400 m above sea level, living among hard-leaf evergreen vegetation interspersed with pine forests. The type locality is included within the Armando Bermúdez National Park, one of the most important protected areas in the Dominican Republic.
