Revision of the weevil genus Pissodes in Mexico with notes on Neotropical Pissodini (Coleoptera, Curculionidae)

This paper treats the 5 species of the genus Pissodes Germar known to occur in Mexico. Three new species are described (P. championi, P. cibriani, and P. mexicanus) and P. guatemaltecus Voss is reported for the first time from Mexico. The genus and the 2 previously described species, P. guatemaltecus Voss and P. zitacuarense Sleeper, are redescribed. A key to the 5 species is included and all species are illustrated using habitus photographs and line drawings of the male phallus and the female 8th sternite and spermatheca. Diagnoses are included for each species and comparisons are made with selected Mexican species and, where applicable, with the 3 species of Pissodes known only from El Salvador. All 5 species have been associated with Pinus. Additional biological information is presented for each when known. Pissodes cibriani and P. zitacuarense are potentially economically important pests in plantations of Christmas trees. Pissodes is the sole generic representative of the Pissodini in the New World. Laccoproctus Schoenherr is transferred to the Molytinae, Anchonini, Cycloterina; Dorytomorpha Hustache is transferred to the Molytinae, Conotrachelini, near Conotrachelus Dejean; and Catiline Champion is transferred from the Ceratopodinae to the Molytinae, Conotrachelini near Dorytomorpha and Conotrachelus. Two species are transferred from Catiline and are now Dorytomorpha elongata (Hustache) NEW COMBINATION and Dorytomorpha tuberculata (Hustache) NEW COMBINATION.
