Abstract

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.
