discussion
Comments. This group was proposed in a recent monograph on the Gryllacrididae classification (Cadena-Castañeda, 2019). It is characterized by a blackish or reddish head, a very well-developed median ocellus (Fig. 1 B, 4 C, 6 A), the subgenital plate of the male without styles and with two or three medium-sized sharp processes (Fig. 1 D, 5 D), and the females with a pair of papillae on each side of the last abdominal sternite (Fig. 6 D-E). Triaenogryllacrae is represented by the monotypic genus, Triaenogryllacris, and the new species described in this paper, all from Colombian and Ecuadorian Andes (Map 1). The Group is distinguished from the other American genera by the tegmen venation corresponding to Type IV (sensu Karny, 1924) and the strange hindwing venation. The males do not have styli, as in the genera of Hyperbaenini. This character is interpreted as convergence, since both groups are found in different subfamilies, and are separated by many other characters such as the shape of the hind femur tegmina, and pattern of wing venation (Cadena-Castañeda, 2019).
