Cryphalini Lindemann, 1877 are a speciose group of mostly miniscule beetles. The tribe Cryphalini is reviewed here which resulted in taxonomic and nomenclatural changes. This revision follows a recent molecular phylogenomic re-analysis focused on the tribe and related scolytine taxa. The analysis demonstrated that the tribe is polyphyletic, as found in other molecular phylogenies. To ensure monophyletic classification, we present a revision of the former tribe with two tribes resurrected, one described, and several genera transferred to other existing tribes. Additionally, extensive generic synonymy, and new combinations are presented. A key, photographs, and illustrations are provided to enable an accurate determination of genera. The revised Cryphalini contains only Cryphalus Erichson, 1836 (=Hypocryphalus Hopkins, 1915 syn. nov.; Margadillius Hopkins, 1915 syn. nov.). Coriacephilini Johnson trib. nov. contains only Coriacephilus Schedl, 1939. Ernoporini Nüsslin, 1911 stat. res. contains Eidophelus Eichhoff, 1876 (=Scolytogenes Eichhoff, 1878 syn. nov.; Ptilopodius Hopkins, 1915 syn. nov.; Ernoporicus Berger, 1917 syn. nov.; Cryphalogenes Wood, 1980 syn. nov.); ErnoporusThomson, 1859 (=Ernocladius Wood, 1980 syn. nov.; Allothenemus Bright and Torres, 2006 syn. nov.); Hemicryphalus Schedl, 1963; and Procryphalus Hopkins, 1915. Trypophloeini Nüsslin, 1911 stat. res. includes the genera Afrocosmoderes Johnson and Jordal gen. nov.; Atomothenemus Bright, 2019; Cosmoderes Eichhoff, 1878 (=Allernoporus Kurentsov, 1941 syn. nov.); Hypothenemus Westwood, 1834 (=Periocryphalus Wood, 1971 syn. nov.); Macrocryphalus Nobuchi, 1981 stat. res.; Microcosmoderes Johnson and Jordal gen. nov.; Microsomus Bright, 2019; Pygmaeoborus Bright, 2019; and Trypophloeus Fairmaire, 1864. Xyloterini LeConte, 1876 is maintained, containing Indocryphalus Eggers, 1939; Trypodendron Stephens, 1830 and Xyloterinus Swaine, 1918. Acorthylus Brèthes, 1922, Cryptocarenus Eggers, 1937, Neocryphus Nunberg, 1956, StegomerusWood, 1967, and Trypolepis Bright, 2019 are transferred to Corthylini LeConte, 1876. Stephanopodius Schedl, 1963 is transferred to Xyloctonini Eichhoff, 1878. As a consequence of generic synonymy, the following new or resurrected combinations are proposed: Cosmoderes euonymi (Kurentsov, 1941) comb. nov.; Cryphalus aciculatus (Schedl, 1939) comb. nov.; Cryphalus afiamalus (Schedl, 1951) comb. nov.;

Subjective species-level changes are minimal. The following synonymies are proposed: Cryphalus papuanus (Schedl, 1973) (=Ernoporus antennarius Schedl, 1974 syn. nov.); Eidophelus concentralis (Schedl, 1975) (=Margadillius concentralis Schedl, 1975 syn. nov.). A neotype for Periocryphalus sobrinus Wood, 1974 and its replacement name Hypothenemus marginatus nom. nov. is designated at USNM due to the holotype being lost and replaced with a different species.
