A new Mexican species of Bolbelasmus Boucomont, 1911 (Coleoptera: Bolboceratidae), with an updated key for related species and a revised status of Eucanthus Westwood, 1848

Abstract

Summary A new species of Bolboceratidae from Mexico, Bolbelasmus (Bolbelasmus) quinquestriatus n. sp., is described and illustrated. The elytra of the new species present five striae between the humeral callus and the elytral suture, a character that is considered diagnostic for the genus Eucanthus. Based in this condition, Eucanthus is proposed as a subgenus of Bolbelasmus. An updated identification key and photographs of related species are provided.
