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 (Licracanthagen. n.) is described and illustrated based on one species (Licracantha formicariasp. n.) and provisionally assigned to Tillomorphini. Three other new species of ant mimic longhorned beetles are described and illustrated: Calliclytus macorissp. n. (Tillomorphini), Tilloclytus baorucosp. n., and Tilloclytus neibasp. n. (Anaglyptini). An identification key and distribution map to all known Hispaniolan species of these two tribes are presented.
