Cota Bolívar, 1887

Fig. 19−21

Type species. Cota saxosa Bolívar, 1887 .

Description. Body surface granulated with spine-like tubercles over the tegument; head and compound eyes inserted slightly below pronotal disc; face oblique; fastigium visible between eyes; antennal groove situated much bellow lower margin of compound eyes, eyes globose with flattened dorsal base; vertex lower than median carina of pronotum; fascial carinae elevated; fastigium of vertex protruding as a horn-like structure (in lateral view) and carinula transversal to vertex, between the eyes, with cusp shape surpassing dorsal margin of the eyes, forming small horns in frontal view (referred to by Hancock (1907) and Bolívar (1887) as tricuspidate form) in C. saxosa ; interocular width of vertex between eyes, in dorsal view, wider than vertical width one compound eye. Pronotum granulated with spine-like tubercles, anteriorly truncated or rounded, median carina conspicuous, continuous with protuberances; lateral lobes directed sidewards; median carina continuous, with two strongly elevated cusps. Tegmina and wings absent. Fore and middle femur with lappets and saxose (i.e., with various lumps and teeth on femora, giving a stone-like appearance, Fig. 22L ) protuberances; hind femur with lappets, genicular teeth conspicuous; the first and third articles of posterior tarsi with subequal length.

Comments. This genus is found in South America and has three species: Cota bispina (Saussure, 1861) from Brazil; C. saxosa Bolívar, 1887 and C. strumosa Bolívar, 1887 from Peru ( Cigliano et al. 2018). Cota has characteristics which do not allow it to be classified in Choriphyllini n. trib. or Mucrotettigini n. trib.; these are spiny protuberances in the face and body, and femora with lappets. We maintain it within the subfamily Cladonotinae until future cladistic analysis can clarify its classification. Bolívar (1887) only provided a general description of Cota .
