Nodubothea gen. nov.,type-species Carneades nodicornis Bates,1881 and Nodubothea zapoteca sp. nov. (Mexico,Tehuantepec) are described. Nodubothea gen. nov. differs from the other genera of Colobotheini by the scape moderately to abruptely clavate, prothorax with median lateral tubercles, elytra without setae, with centro-basal ridge and lateral carina well defined, and posterior lateral margin of metasternum with elevation limited anteriorly by transversal deep sulcus. New synonym proposed: Sparna bosqi Gilmour, 1954 = Carterica soror Belon, 1896, the comparison of the photograph of the type of Carterica soror Belon, 1896 with a paratype of Sparna bosqi Gilmour, 1954, allowed us to propose the synonymy. New combinations: Colobothea grallatrix Bates, 1865, does not have the male forelegs elongated and with rows of acute spines in the ventral face of the tibiae, which are characters of the genus Cathexis Thomson, 1860, thus, we propose to return it to the original genus Colobothea Lepeletier & Audinet-Serville, 1825. Sangaris optata (Pascoe, 1866), comb. nov. from Carterica Pascoe, 1858, the cylindrical shape of the body, elytra without dorsal carinae and with abbreviated lateral carinae in the anterior third, the vertical epipleura and the length of the ovipositor, projected beyond the elytral apices, justified the proposed new combination.
