A new genus for \u3ci\u3eStromatium chilensis\u3c/i\u3e Cerda, 1968 (Coleoptera: Cerambycidae: Cerambycinae: Hesperophanini) from Chile

Stromatium chilensis Cerda, 1968, an endemic species from Chile, is placed in Malcho Mondaca and Beéche, new genus (Coleoptera: Cerambycidae: Cerambycinae: Hesperophanini). The new genus is compared with Stromatium Audinet-Serville, included in a previous key to Hesperophanini, and a diagnosis and illustrations of the species are provided. Stromatium chilensis Cerda, 1968, especie endémica de Chile, es ubicada en Malcho Mondaca y Beéche, nuevo género (Coleoptera: Cerambycidae: Cerambycinae: Hesperophanini). El nuevo género es comparado con Stromatium Audinet-Serville, e incluido en la clave anterior de Hesperophanini. Se aporta una diagnosis e ilustraciones de la especie. The genus Stromatium Audinet-Serville, 1834, considered to be one of the most economically significant longhorn beetle genera (due to the species’ ability to develop in seasoned timber, and be transported through commerce), includes six species known mainly from Europe, Africa, Asia, Australia, and South America (Martins and Galileo 1999; Jin et al. 2019; Tavakilian and Chevillotte 2021). One species was described from Chile (Cerda 1968). How­ever, it does not belong to the genus Stromatium (Martins and Galileo 1999; Jin et al. 2019). Recently, while we studied specimens of an undetermined cerambycid collected in the Andes and coastal range of Chile, we noticed that they correspond to Stromatium chilensis Cerda, 1968. This species, endemic to the Nothofagus Blume forests of central-southern Chile is herein transferred to a new taxon. We also include habitus photographs of the species to help with correct identification
