[Host plants of Cerambycidae (Coleoptera) from northwest and central Argentina]

Seventy four species of Cerambycidae (Coleoptera) were reared from forty eight host plants found into Yungas, Chaco and Prepuna phytogeografical provinces. The host plants belong Anacardiaceae, Asclepiadaceae, Bignoniaceae, Cactaceae, Cucurbitaceae, Euphorbiaceae, Juglandaceae, Leguminosae sensu lato (Caesalpinaceae, Fabaceae, Mimosaceae), Loranthaceae, Rhamnaceae, Rutaceae, Salicaceae, Sapindaceae, Solanaceae, Ulmaceae and Vitaceae. Some species of Cerambycidae and their host plants show similar distribution patterns: from northeastern Brazil through Paraguay and reach the Argentina at both sides of the Chaco Provine: at the east, along the river systems through Buenos Aires, and the at the west into forests of the Yungas Province or into North Sierra Chaco, a probably relictual community. Others species are restricted to the South America area of Prosopis, that comprise the Chaco, Monte and Espinal biogeographical provinces, and live in host plants of chaquenian lineage mainly Leguminosae sensu lato and Ulmaceae.
