Dataset Information

Blakealtica, a new genus of flea beetles (Coleoptera, Chrysomelidae, Galerucinae, Alticini) from the Dominican Republic.

ABSTRACT: Blakealtica fusca a new genus and new species from the Dominican Republic is described and illustrated. In addition to external features, beetle thoracic sclerites (including metendosternite) are fully examined and illustrated. Blakealtica is similar to Monomacra Chevrolat,1836 and related genera (Disonycha Chevrolat, 1836, Hemilactica Blake, 1937, Myrmeconycha Konstantinov & Tishechkin, 2017, Parchicola Bechyne & Bechyne, 1975, Pseudodisonycha Blake, 1954, and Rosalactica Bechyne & Bechyne, 1977) as all studied representatives of these genera are missing the sclerotized vaginal palpi or have them membranous and otherwise poorly developed. This feature may be unique for the Monomacra group of genera as it has not been seen anywhere else in flea beetles.

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.
