A new species of Aclees from Taiwan and notes on other species of the genus (Coleoptera: Curculionidae: Molytinae). A new species of Aclees from Taiwan

A molecular and morphological analysis of the species of Aclees native to Taiwan allowed recognition of a new species of the genus, that is described here as Aclees aenigmaticus Meregalli & Boriani, new species. The study revealed also that the species of Aclees that has been introduced into Italy and France shares the mitochondrial cox-1 gene sequence with specimens of A. taiwanensis from Taiwan. Taiwan is thus assumed to be the country of origin of the specimens introduced to Europe. A key to the species of Aclees present in Taiwan is provided. A lectotype is designated for Aclees foveatus, and some remarks on A. hirayamai are given. Pagiophloeus visayus Heller, 1929 is transferred to the genus Aclees, comb. n.
