Revision of the Bark Beetle Genera Within the Former Cryphalini (Curculionidae: Scolytinae)

Abstract

Abstract 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 CryphalusErichson, 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 EidophelusEichhoff, 1876 (=Scolytogenes Eichhoff, 1878 syn. nov.; PtilopodiusHopkins, 1915syn. nov.; ErnoporicusBerger, 1917syn. nov.; CryphalogenesWood, 1980syn. nov.); ErnoporusThomson, 1859 (=ErnocladiusWood, 1980syn. nov.; AllothenemusBright and Torres, 2006syn. nov.); Hemicryphalus Schedl, 1963; and ProcryphalusHopkins, 1915. Trypophloeini Nüsslin, 1911 stat. res. includes the genera Afrocosmoderes Johnson and Jordal gen. nov.; AtomothenemusBright, 2019; Cosmoderes Eichhoff, 1878 (=AllernoporusKurentsov, 1941syn. nov.); HypothenemusWestwood, 1834 (=PeriocryphalusWood, 1971syn. nov.); MacrocryphalusNobuchi, 1981stat. res.; Microcosmoderes Johnson and Jordal gen. nov.; MicrosomusBright, 2019; PygmaeoborusBright, 2019; and TrypophloeusFairmaire, 1864. Xyloterini LeConte, 1876 is maintained, containing Indocryphalus Eggers, 1939; TrypodendronStephens, 1830 and XyloterinusSwaine, 1918. AcorthylusBrèthes, 1922, CryptocarenusEggers, 1937, Neocryphus Nunberg, 1956, Stegomerus Wood, 1967, and TrypolepisBright, 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.;
