Six new species of Coleoxestia Aurivillius, 1912 (Cerambycidae, Cerambycinae, Cerambycini) are described: C. clarkei from Bolivia; C. chemsaki and C. eyai from Peru; C. fragosoi and C. rafaeli from Brazil; and C. hovorei from Ecuador. Coleoxestia rachelae Eya and Chemsak is also newly recorded from Peru (new country record). Dorsal, ventral and lateral illustrations along with illustrations of various other structures are provided for each of the new species. In some cases, existing key couplets by Eya and Chemsak (2005) or Martins and Monné (2005) are modifi ed to help separate a new species from similar existing species. A reproduction of the general descriptive terminology for the head, prothorax and antennomeres of Coleoxestia, from Fragoso (1993), is also included in the illustrations.
