The world species of Limotettix Sahlberg are reviewed, and 13 new Nearctic species are described: in the typical subgenus — L. conservatus; in the new subgenus Dryola — L. elegans, L. minuendus; in subgenus Neodrylix — L. urnura; in subgenus Ophiolix — L. nigristriatus, L. pseudosphagneticus, L. xanthus; and in subgenus Scleroracus — L. brooksi, L. medleri, L. obesura, L. scudderi, L. strictus, and L. zacki. Limotettix (L.) emeljanovi is proposed to replace L. luteolus Emel'janov, 1962, nec L. (Scleroracus) luteolus (Sleesman, 1930). The 80 known world species are arranged phylogenetically. From this analysis the genus evidently evolved in the New World from swale and fen inhabiting ancestors that fed on spike-rush. Their bog-inhabiting descendents fed on various rushes and sedges, but apomorphic lineages transferred to ericaceous plants. Adaptation to ericaceous plants permitted invasion of drier habitats, with subsequent radiation on other semiwoody plants, principally Asteraceae and Symphoricarpos.
