A brief review of the classification history of the subfamily Colydiinae is provided, followed by a provisional diagnosis for the group. The 47 genera of New World Colydiinae (Colydiidae auctorum) are reviewed, with an illustrated key to genera, a representative habitus of each genus, a list of all 305 described species currently considered valid, each placed into the appropriate recognized genus, with full citations for each. Numerous nomenclatural changes are noted. Opostirus Kirsch is transferred to the Tenebrionidae: Eudysantina, new placement. The Adimerini Sharp 1894 are synonymized with Synchitini Erichson, 1845, new synonymy. In the Acropini, Lemmis Pascoe, 1860 = Acropis Burmeister, 1840, new synonymy, with Acropis caelatus (Pascoe, 1860), new combination and Acropis tuberosus (Grouvelle, 1896), new combination. Acropis fryi Pascoe, 1860 = Acropis tuberculifera Burmeister, 1840, new synonymy and Acropis incensa Pascoe, 1860 = Acropis aspera Pascoe, 1860, new synonymy. In the Synchitini, Anisopaulax Reitter, 1877 = Lasconotus Erichson, 1845, new synonymy, with Lasconotus brucki (Reitter, 1877), new combination. Pristoderus brasiliensis (Grouvelle, 1896), new combination follows synonymization of Ulonotus Erichson with Pristoderus. Eucicones Sharp, 1894 = Catolaemus Sharp, 1894 = Cacotarphius Sharp, 1894, new synonymies, with Eucicones minutus (Sharp, 1894), new combination and Eucicones compressus (Sharp, 1894), new combination. Reylus Ivie, Lord, Foley, and Ślipiński is a new replacement name for Erylus Dajoz, 1969 [not Erylus Gray, 1867 (Porifera)]. Eulachus Erichson, 1845 = Anarmostes Pascoe, 1860, new synonymy, with Anarmostes costatus (Erichson, 1845), new combination, Bitoma quinquecarinata (Chevrolat, 1864), new combination, and Bitoma semifuliginosa Chevrolat, 1864), new combination. Hystricones Sharp, 1894 = Paryphus Erichson, 1845, new synonymy, with Paryphus armatus (Sharp, 1894), new combination and the following species moved to Colobicones Grouvelle, 1918: Colobicones vagans (Arrow, 1927), new combination; Colobicones hirtus (Ślipiński, 1985), new combination; and Colobicones papuanus (Ślipiński, 1985), new combination. Labrotrichus Sharp, 1894 = Neotrichus Sharp, 1885, new synonymy, with Neotrichus aberrans (Sharp), new combination and Neotrichus verrucatus (Hinton, 1935), new combination. Microsicus Sharp, 1894 = Synchita Hellwig in Schneider, 1792, new synonymy, resulting in changes for the Japanese species Synchita constricta (Aoki, 2012), new combination and Synchita parvula Guérin-Méneville, 1844, return to a previous combination. Synchita grouvellei Ivie, Lord, Foley, and Ślipiński, new replacement name is proposed for Microsicus minimus Grouvelle, 1898 [not Sharp, 1885]. The earlier synonymization of Cicones Curtis, 1827 with Synchita results in Synchita africana (Grouvelle, 1905), new combination, Synchita amoena (Fairmaire, 1850), new combination, Synchita colorata (Motschulsky, 1863), new combination, Synchita compacta (Grouvelle, 1918), new combination, Synchita eichelbaumi (Grouvelle, 1914), new combination, Synchita lata (Grouvelle, 1919), new combination, Synchita madagascariensis (Grouvelle, 1896), new combination, Synchita minor (Pope, 1954) new combination, Synchita minuta (Sharp, 1885) new combination, Synchita oblonga (Sharp, 1885), new combination, Synchita picta (Erichson, 1845), new combination, Synchita scotti (Grouvelle, 1918), new combination, and Synchita squamosa (Grouvelle, 1896), new combination. Synchita lecontei Ivie, Lord, Foley, and Ślipiński, new replacement name is proposed for Synchita variegata LeConte, 1858 [not Hellwig in Schneider, 1792]. The species formerly placed in Catolaemus belong in Synchita, resulting in Synchita exilis (Grouvelle, 1898), new combination and Synchita multimaculata (Grouvelle, 1902), new combination. Cicones bitomoides Sharp, 1885, Cicones hayashii Sasaji, 1971, Cicones niveus Sharp, 1885, Cicones oculatus Sharp, 1885, Cicones rufosignatus Sasaji, 1984, and Cicones variegatus (Hellwig in Schneider, 1792) are returned to Synchita as returned to previous combinations. Synchita hirsuta Aoki, 2008 is also returned to original combination from Microsicus. Pseudotaphrus Stephan, 1989 [not Cossmann, 1888 (Mollusca: Rissoiidae)], including the preoccupied replacement name Stephaniolus Ivie, Ślipiński, and Węgrzynowicz, 2002 = Coxelus Dejean, 1821, new synonymy, with Coxelus longus (Stephan, 1989), new combination.
