Pityophthorus Eichhoff ( Coleoptera : Curculionidae )

Species within Pityophthorus can be diagnosed by pronotal asperities and the presence of a sclerotized septum in both antennal sutures of the club, and by usually sparse vestiture and bisulcate declivity. Individuals of this genus colonize cut or broken twigs and small branches of several conifers and broadleaves ( Bright 1981). A few species in this large genus vector diseases such as the conifer pathogen Fusarium circinatum Nirenberg & O’Donnell (Nectriac- eae), carried by Pityophthorus setosus Blackman and Pityophthorus carmeli Swaine (both Coleoptera : Curculionidae ), or the walnut pathogen Geosmithia morbida Kolarik, Freeland, Utley & Tisserat (unassigned), carried by Pityophthorus juglandis Blackman ( Coleoptera : Curculionidae ), a species endemic to Mexico and the south- western USA.
