Abstract
The genus Copelatus Erichson, 1832 (Coleoptera, Dytiscidae, Copelatinae) of Madagascar is revised in two parts. This review is restricted to the Copelatus species that have fewer than ten elytral + one submarginal stria, including all species except those of the erichsonii species group. Both morphological and molecular (mitochondrial COI) data are used in an integrative taxonomic approach. Thirteen species are recognised, of which five are described as new: Copelatusankaratrasp. nov., Copelatuskelysp. nov., Copelatuspseudostriatussp. nov., Copelatussafiotrasp. nov. and Copelatusvokokasp. nov.Copelatusunguicularis Régimbart, 1903 and Copelatusapicalis Fairmaire, 1898 are both transferred to the genus Madaglymbus Shaverdo & Balke, 2008 (comb. nov.). CopelatusmimetesGuignot 1957 is a junior synonym of the widespread Afrotropical–Arabian Copelatuspulchellus (Klug, 1834) (syn. nov.). Copelatusmarginipennis (Laporte, 1835) is reinstated (stat. nov.) as a valid species with Copelatusaldabricus Balfour-Browne, 1950 and Copelatusaldabricusvar.simplex Guignot, 1952 as junior synonyms (syn. nov.). We designate lectotypes for Colymbetesmarginipennis Laporte, 1835 and Copelatusobtusus Boheman, 1848. Copelatusperidinus Guignot, 1955 is recorded for Madagascar for the first time and Copelatusnodieri Régimbart, 1895 is rejected as a species present in Madagascar.
