Lucasianus levaillantii, a rare species from South-West Mediterranean (Algeria, Morocco, France, Portugal, Spain), has been described from Oran environs (Algeria) as Cerambyx ? Levaillantii by Pierre Hippolyte Lucas in 1849 [▽]. The new genus for this interesting taxon, named Lucasianus in honor of the discoverer, was estabilished by Maurice Pic in 1891 [❖]. Larvae of this crepuscular species with summer-early autumn acivity develop in dead or dying branches of conifers, especially from Cupressaceae family. Local populations of this originally North-African species are known from the Iberian peninsula and South-France, where was species probably introduced together with ornamental Cupressaceae or wood in the early 20th century [✧].
