REVISION OF THE GENUS TYLOSIS (COLEOPTERA, CERAMBYCIDAE)

We revise the eight species of the longhorn beetle genus Tylosis, including T. dimidiata Bates, T. hilaris Linsley, T jimenezi Duges, T. maculatus LeConte, T. oculatus LeConte, T. puncticollis Bates, T suturalis White, and T. triangularis Monne and Martins. We consider T puncticollis arizonicus as a synonym of T puncticollis. Tylosis maculatus, T. oculatus, and T. puncticollis are common and widely distributed. Some species, especially T. dimidiata, T. triangularis, and T. hilaris, are rarer and have limited distributions. We provide a key for the identification of the eight species. Specimens are most commonly collected during the months of july, August and September.
