New records of bark and ambrosia beetles (Coleoptera: Scolytinae) from Cuba with description of a new species
Abstract
We present a reassessment of the diversity of bark and ambrosia beetles in Cuba. For the first time in decades, an official Cuban-American binational collaboration allowed us to re-visit all known entomology collections in Cuba, and collect in the field. There are at least 94 species of scolytine beetles in Cuba. We report a new species, Xylosandrus aurinegro Gomez & Hulcr (Coleoptera: Curculionidae), and 7 new species records, including the first genus record for Dryocoetoides Hopkins and Tricolus Blandford (both Coleoptera: Curculionidae) for the island. In terms of species with potential concern to the USA, we corroborate a subspecies of Ips calligraphus Wood & Bright (Coleoptera: Curculionidae) that acts as a pine pest in Cuba and is not yet present in North America.

En este trabajo evaluamos la diversidad de escarabajos de corteza y ambrosia de Cuba. Por primera vez en décadas, una colaboración oficial entre Cuba y Estados Unidos nos permitió visitar todas las colecciones entomológicas de Cuba y realizar trabajo de campo. Existen al menos 94 especies de escolitinos en Cuba. Reportamos una nueva especie, Xylosandrus aurinegro Gomez & Hulcr (Coleoptera: Curculionidae), y 7 nuevos registros, incluyendo el primer registro de los géneros Dryocoetoides Hopkins y Tricolus Blandford (ambos Coleoptera: Curculionidae) en la isla. En términos de especies de interés para EEUU, se corroboró la existencia de una subespecie de Ips calligraphus Wood & Bright (Coleoptera: Curculionidae), una plaga de pino en Cuba no presente en América del Norte.
