Palearctic flea beetle and pest of hops and Cannabis, Psylliodesattenuata (Coleoptera, Chrysomelidae, Galerucinae), new to North America.

ABSTRACT:

Background

The univoltine leaf beetle Psylliodesattenuata (Koch, 1803) is a pest of Cannabis and Humulus (Cannabaceae) and native to the Palaearctic Region, known from eastern Asia to western Europe.

New information

First North American records are presented for P.attenuata from Canada: Ontario and Québec. Adult beetle feeding damage to hops Humuluslupulus L. (Cannabacaea) plants is recorded from Québec. Diagnostic information is presented to distinguish P.attenuata from other North American Chrysomelidae and a preliminary assessment of its potential to spread in North America is presented. While our climate analysis is limited by a lack of data, it appears P.attenuata is physiologically capable of persisting throughout the range of Humulus in North America.The United States of America and Canada are now known to be home to 71 or more species of adventive Chrysomelidae.

Project description:A revision of the Alticini genera from the Afrotropical region is reported. The paper includes the following for the flea beetle fauna occurring in Sub-Saharan Africa and Madagascar: a key to their identification; habitus photos of all the genera; microscope and scanning electron micrographs of many diagnostic morphological characters; and an updated annotated catalogue with biogeographical notes that include new distributional data. The following new synonymies are proposed: Aphthona Chevrolat, 1836 = Ethiopia Scherer, 1972 syn. n.; Sanckia Duvivier, 1891 = Eugonotes Jacoby, 1897 syn. n.; Eurylegna Weise, 1910a = Eurylegniella Scherer, 1972 syn. n.; Kimongona Bechyné, 1959a = Mesocrepis Scherer, 1963 syn. n.; Diphaulacosoma Jacoby, 1892a = Neoderina Bechyné, 1952 syn. n.; Sesquiphaera Bechyné, 1958a = Paropsiderma Bechyné, 1958a syn. n.; Podagrica Chevrolat, 1836 = Podagricina Csiki in Heikertinger and Csiki 1940syn. n.; Amphimela Chapuis, 1875 = Sphaerophysa Baly, 1876a syn. n. The following new combinations are proposed: Blepharida insignis Brancsik, 1897 = Xanthophysca insignis (Brancsik, 1897) comb. n.; Blepharida multiguttata Duvivier, 1891 = Xanthophysca multiguttata (Duvivier, 1891) comb. n.; Hemipyxis balyana (Csiki in Heikertinger and Csiki 1940) = Pseudadorium balyanum (Csiki in Heikertinger and Csiki, 1940) comb. n.; Hemipyxis brevicornis (Jacoby, 1892a) = Pseudadorium brevicornis (Jacoby, 1892a) comb. n.; Hemipyxis cyanea (Weise, 1910b) = Pseudadorium cyaneum (Weise, 1910b) comb. n.; Hemipyxis gynandromorpha Bechyné, 1958c = Pseudadorium gynandromorphum (Bechyné, 1958c) comb. n.; Hemipyxis latiuscula Bechyné, 1958c = Pseudadorium latiusculum (Bechyné, 1958c) comb. n.; Hemipyxis soror (Weise, 1910b) = Pseudadorium soror (Weise, 1910b) comb. n. The genera Buphonella Jacoby, 1903aand Halticopsis Fairmaire, 1883a are transferred to the tribe Galerucini; the genus Biodontocnema Biondi, 2000 stat. prom. is considered to be valid and reinstated at generic level. Finally, a zoogeographical analysis of the flea beetle fauna in the Afrotropical region is provided.
