In this first part of the World catalogue of genus-group names in Elateridae, a nomenclatural review of the genera belonging to ten subfamilies is provided. All names are given with author name, year, and page of publication, type species, and type fixation. We list 132 valid genera in Agrypninae, 2 in Campyloxeninae, 4 in Hemiopinae, 11 in Lissominae, 2 in Oestodinae, 8 in Parablacinae, 2 in Physodactylinae, 2 in Pityobiinae, 1 in Subprotelaterinae, and 7 in Tetralobinae. GeneraAnathesisCandèze, 1865,AntitypusCandèze, 1882,ChrostusCandèze, 1878,DorygonusCandèze, 1859 (with subgenus Rygodonus Fleutiaux, 1932), andMacromaloceraHope, 1834 are tentatively placed as Agrypninaeincertae sedis.ParadrapetesvillosusFleutiaux, 1895 is designated as the type species forParadrapetesFleutiaux, 1895. Two new genera are proposed based on species previously incorrectly used as type species forAbiphisFleutiaux, 1926 andLycoreusCandèze, 1857. These genera areNeoabiphisKundrata & Bouchard,gen. n.(type species:ElaternobilisIlliger, 1800) andNeolycoreusKundrata & Bouchard,gen. n.(type species:L.regalisCandèze, 1857), respectively. The following new combinations are proposed for species hitherto included inAbiphisFleutiaux, 1926:Neoabiphiscandezei(Alluaud, 1896),comb. n.,N.fairmairei(Fleutiaux, 1903),comb. n.,N.goudoti(Fleutiaux, 1942),comb. n.,N.insignis(Klug, 1833),comb. n.,N.nobilis(Illiger, 1800),comb. n., andN.viettei(Girard, 1966),comb. n.The following new combinations are proposed for species hitherto included inLycoreusCandèze, 1857:Neolycoreusalluaudi(Candèze, 1900),comb. n.,N.corpulentus(Candèze, 1899),comb. n.,N.cyclops(Candèze, 1865),comb. n.,N.decorsei(Fleutiaux, 1903),comb. n.,N.dux(Candèze, 1857),comb. n.,N.goudotii(Laporte, 1838),comb. n.,N.madagascariensis(Gory, 1832),comb. n.,N.oculipennis(Fairmaire, 1903),comb. n.,N.orbiculatus(Schwarz, 1901),comb. n.,N.regalis(Candèze, 1857),comb. n.,N.sicardi(Fleutiaux, 1942),comb. n.,N.triangularis(Fleutiaux, 1942),comb. n.,N.triocellatus(Laporte, 1838),comb. n., andN.vicinus(Fleutiaux, 1942),comb. n.The following new combinations are proposed for species hitherto incorrectly included inPlectrosternusLacordaire, 1857:Legnarufa(Lacordaire, 1857),comb. n.,L.convexa(Vats, 1991),comb. n.,L.coolsi(Schimmel, 1996),comb. n., andL.foveata(Patwardhan & Athalye, 2012),comb. n.This research revealed a nomenclatural problem threatening the stability of the well-established valid genus nameAdeloceraLatreille, 1829. An application to the International Commission on Zoological Nomenclature will be necessary in this case to maintain stability. Additionally, we act here as First Revisers (ICZN 1999, Art. 24.2) in giving precedence toLucariusGistel, 1848 (Staphylinidae) overLucariusGistel, 1848 (Elateridae).
