Abstract

The Neotropical members formerly included in Earinus Wesmael, 1837 are transferred to a new genus, Chilearinus Sharkey gen. nov. Presently three Nearctic species of Earinus are recognized, i.e., Earinuserythropoda Cameron, 1887, Earinuslimitaris Say,1835, and Earinuszeirapherae Walley, 1935, and these are retained in Earinus. Earinuschubuquensis Berta, 2000 and Earinusscitus Enderlein, 1920 are transferred to Chilearinus, i.e., C.chubuquensis, and C.scitus, comb. nov. One other species is transferred to Chilearinus, i.e., Microgasterrubricollis Spinola, 1851, Chilearinusrubricollis, comb. nov. Two other Neotropical species, Earinushubrechtae Braet, 2002 and Earinusbourguignoni Braet, 2002 were described under the genus Earinus but are here transferred to Lytopylus, L.hubrechtae, and L.bourguignoni comb. nov. Two new species of Chilearinus are described, C.covidchronos and C.janbert spp. nov. The status of Agathislaevithorax Spinola,1851, Agathisrubricata Spinola,1851, and Agathisareolata Spinola, 1851 is discussed. A neotype is designated for Earinuslimitaris (Say, 1835) and diagnosed with a COI barcode. Earinusaustinbakeri and Earinuswalleyi spp. nov. are described. The status of both Earinus and Chilearinus in the Americas is discussed. A revised key to the genera of Agathidinae of the Americas is presented.
