  • Serge Laplante


Tragosoma soror (Coleoptera: Cerambycidae: Prioninae), a new Nearctic species, is described and compared
to its North American congeners. Tragosoma harrisii LeConte, revised status, and Tragosoma spiculum
Casey, revised status are both resurrected from synonymy and considered valid species distinct from T. depsarium
(Linnaeus). The Mexican T. nigripenne Bates is confi rmed as a valid species. Tragosoma chiricahuae Linsley, new
synonym, is placed in synonymy under T. spiculum Casey, and T. sodale Casey, new synonym, T. parvicolle
Casey, new synonym, and T. repens Casey new synonym are placed in synonymy under T. harrisii. Tragosoma
repens is a junior objective synonym of T. parvicolle. A lectotype is designated for T. sodale. An updated synonymical
and distributional checklist of Tragosoma of the world is provided.
