The new doryctine genus Sergey gen. n. is described with four new species (S. cubaensis Zaldívar-Riverón & Martínez, sp. n., S. coahuilensis Zaldívar-Riverón & Martínez, sp. n., S. tzeltal Martínez & Zalídivar-Riverón, sp. n., S. tzotzil Martínez & Zalídivar-Riverón, sp. n.) from temperate forests of Mexico and Cuba. Similar to many other doryctine taxa, the new genus has a considerably elongated, petiolate basal sternal plate of the first metasomal tergite, although it can be distinguished from these by having the mesoscutum sharply declivous anteriorly with sharp anterolateral edges. The described species have been characterised molecularly based on two mitochondrial (COI, cyt b) and one nuclear (28S) gene markers. Based on the mitochondrial gene genealogies reconstructed, the evidence suggests the existence of incomplete lineage sorting or hybridization in the populations from Chiapas and Oaxaca assigned to S. tzeltal sp. n.
