New myrmecomorphous longhorned beetles from Haiti and the Dominican Republic with a key to Anaglyptini and Tillomorphini of Hispaniola (Coleoptera, Cerambycidae, Cerambycinae)

First records of the tribes Anaglyptini and Tillomorphini (Coleoptera: Cerambycidae: Cerambycinae) are documented for Hispaniola. A new genus of a highly myrmecomorphic longhorned beetle (Licracantha gen. n.) is described and illustrated based on one species (Licracantha formicaria sp. n.) and provisionally assigned to Tillomorphini. Three other new species of ant mimic longhorned beetles are described and illustrated: Calliclytus macoris sp. n. (Tillomorphini), Tilloclytus baoruco sp. n., and Tilloclytus neiba sp. n. (Anaglyptini). An identification key and distribution map to all known Hispaniolan species of these two tribes are presented.
