Abstract

The genusCopelatusErichson, 1832 (Coleoptera, Dytiscidae, Copelatinae) of Madagascar is revised in two parts. This review is restricted to theCopelatusspecies that have fewer than ten elytral + one submarginal stria, including all species except those of theerichsoniispecies 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:Copelatus ankaratrasp. nov.,Copelatus kelysp. nov.,Copelatus pseudostriatussp. nov.,Copelatus safiotrasp. nov.andCopelatus vokokasp. nov.Copelatus unguicularisRégimbart, 1903 andCopelatus apicalisFairmaire, 1898 are both transferred to the genusMadaglymbusShaverdo & Balke, 2008 (comb. nov.).Copelatus mimetesGuignot 1957 is a junior synonym of the widespread Afrotropical–ArabianCopelatus pulchellus(Klug, 1834) (syn. nov.).Copelatus marginipennis(Laporte, 1835) is reinstated (stat. nov.) as a valid species withCopelatus aldabricusBalfour-Browne, 1950 and Copelatus aldabricus var. simplex Guignot, 1952 as junior synonyms (syn. nov.). We designate lectotypes forColymbetes marginipennisLaporte, 1835 andCopelatus obtususBoheman, 1848.Copelatus peridinusGuignot, 1955 is recorded for Madagascar for the first time andCopelatus nodieriRégimbart, 1895 is rejected as a species present in Madagascar.
