Abstract 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 othernew 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. Keywords Island, endemic, mimicry, myrmecophily, West Indies, taxonomy

Introduction Hispaniolais among the most critical biodiversity regions in the world and is part of the Caribbean Islands Hotspot (Conservation International and McGinley 2008). The entomological riches there were first discovered and described by Palisot de Beauvois

(1805–1821). Despite periods of intense beetle collecting in the late 19th, early 20th, and early 21st centuries, many species of Hispaniolan Cerambycidae still remain undescribed. In the last 5 years, 20 new species representingabout 12% of the known fauna have been described, demonstrating how poor our prior knowledge was (Lingafelter 2008, 2010; Lingafelter and Micheli 2009; Lingafelter and Nearns 2007; Lingafelter and Woodley 2007). Batesian mimicry has been well documented in longhorned beetles and has been summarized in Shelford (1902) and Linsley (1959). The genera in the tribe Tillormorphini Pascoe [and some inAnaglyptini Lacordaire] are considered as group mimics of ants with generalized structural modifications (Linsley 1959). Morphological adaptations that suggest an antlike facies include a constriction of the elytra around the middle, accentuated with a light colored fascia or ivory colored callus (representing a petiole) and an inflated pronotum (representing a large ant head when combined with thesmaller, actual head) (McIver and Stonedahl 1993). Studies such as Fisher (1932), Micheli (2003), Chalumeau and Touroult (2005), and Micheli (2010) have documented the species diversity in the West Indies for Anaglyptini and Tillomorphini, nearly all of which display varying degrees of myrmecomorphy. Several species have been documented as collected with ants in Puerto Rico and Hispaniola,...
