Genus Guides
2Tribe Xylosteini is a small, primitive group of longhorn beetles (Cerambycidae: Lepturinae) containing rare forest-dwelling . In Türkiye, the tribe comprises four species across two : Leptorhabdium (exclusively deciduous-feeding) and Xylosteus (feeding on both deciduous and coniferous trees). These beetles are considered forest pests of ecological and economic significance due to their wood-boring larval habits.
