Timarcha latreille (Coleoptera: Chrysomelidae, Chrysomelinae)
نویسندگان
چکیده
The leaf-beetle genus Timarcha Latreille comprises about four subgenera, 125 species and 30 subspecies, spread in eastern North America and around the Mediterranean basin. They are absent from Syria, Lebanon, Israel, and Egypt, where very probably European and African species once met, but were eradicated during the Pleistocene desertification. In Libya, it survives along the coast on the western side and in Cyrenaica, but also survives on some oases, 80 km south. Timarcha does not reach or survive in the central Sahara (Hoggar, 2,918 m) where some Chrysolina live.
