The North American genus Ceratagallia Kirkaldy, 1907 is redefined to include subgenus Aceratagallia Kirkaldy, 1907 (= Ionia Ball, 1933, syn.nov.) with 78 species in two subgenera. Two additional new species are unplaced to subgenus: C. acerata from Oregon, and C. emarginata from Mexico. The typical subgenus Ceratagallia has 30 species, including C. gillettei (Osborn & Ball, comb.nov.), C. sordida (Oman, comb.nov.), and two new species C. ana from Mexico and C. vipera from Washington state. Subgenus Aceratagallia has 46 species, all new combinations under Ceratagallia. The economic "species" formerly known as "sanguinolenta" is divided into the Canadian clover leafhopper C. humilis (Oman) and the American clover leafhopper C. agricola sp.nov. Other new taxa in subgenus Aceratagallia include 18 new species and seven new subspecies: alaskana (ssp. of siccifolia) from Alaska; omani on the Pacific coast from Oregon to British Columbia; clino and lophia from the Oregon interior; compressa (ssp. of siccifolia), gallus, modesta, okanagana, and zacki (ssp. of nanella) from intermontane valleys of the Pacific northwest and southwestern mountains; interior (ssp. of humilis) and rossi from the Sonoran subregion; australis (ssp. of nanella), coma, ebena, entoma, falcata, oionus, and venosa from Mexico and Texas; alvarana (ssp. of humilis), cerea, cristula, harrisi, semiarida, and viator widespread between the Appalachian and Rocky Mountains; and whitcombi (ssp. of robusta) from Florida to Arizona. Four former species are reduced to subspecies: compacta Oman and poudris Oman in C. robusta (Oman), helveola Oman in C. cinerea (Osborn & Ball), and truncata Oman in C. humilis. The taxa are keyed and illustrated, and their phylogeny is discussed.

Le genre nord-américain Ceratagallia Kirkaldy, 1907 est redéfini et inclut maintenant le sous-genre Aceratagallia Kirkaldy, 1907 (= Ionia Ball, 1933 syn. nov.), comptant 78 espèces et deux sous-genres. Deux nouvelles espèces additionnelles ne peuvent être assignées à un sous-genre; C. acerata d’Oregon et C. emarginata du Mexique. Le sous-genre type Ceratagallia compte 30 espèces, dont C. gillettei (Osborn et Ball, comb, nov.), C. sordida (Oman, comb, nov.) et deux nouvelles espèces, C. ana du Mexique et C. vipera de l’état du Washington. Chez le sous-genre Aceratagallia on reconnaît 46 espèces, maintenant toutes de nouvelles combinaisons, dans le genre Ceratagallia. L’« espèce » économique connue à ce jour sous le nom de « sanguinolenta » regroupe en fait deux espèces, C. humilis (Oman) du Canada et C. agricola sp. nov. des États Unis. Parmi les nouveaux taxons du sous-genre Aceratagallia, on compte 18 nouvelles espèces et sept nouvelles sous-espèces : alaskana (ssp. de siccifolia) d’Alaska; omani sur la côte ouest, de l’Oregon à la Colombie-Britannique; clino et lophia de l’intérieur de l’Oregon; compressa (ssp. de siccifolia), gallus, modesta, okanagana et zacki (ssp. de nanella) des vallées intérieures du nord-ouest des États Unis et des montagnes du sud-ouest; interior (ssp. de humilis) et rossi de la sous-région du Sonora; australis (ssp. de nanella), coma, ebena, entoma, falcata, oionus et venosa du Mexique et du Texas; alvarana (ssp. de humilis), cerea, cristula, harrisi, semiarida et viator, répandues des Appalaches aux Rocheuses, enfin whitcombi (ssp. de robusta) de Floride et d’Arizona. Quatre espèces sont réduites ici au rang de sous-espèces : compacta Oman et poudris Oman qui deviennent sous-espèces de C. robusta (Oman), helveola Oman, sous-espèce de C. cinerea (Osborn et Bail) et truncata Oman, sous-espèce de C. humilis. Une clé illustrée permettra d’identifier les divers taxons et leur phylogénie fait l’objet d’une discussion.
