Gryllacridinae Blanchard 1845

Subfamily Gryllacridinae Blanchard, 1845 n. sensu.

Diagnosis: Small to mid-sized (5–30 mm. aprox). Body usually robust, and wing development variable, from wingless to fully winged (but in most species the wings barely cover the tip of the abdomen) (Figs. 4, 57, 62, 67, 81, 82, 84, 87, 93, 109, 110, 132, 146, 151). If wings are present, these are ovoid and fold on the abdomen; if they go further they fold over and cover the last abdominal tergites (Figs. 81, 84). Venation type III, IV and V sensu Karny (Figs. 73, 74, 106, 143), that is usually reduced or if it is not, it is not as developed as in Hyperbaeninae. Vein M not originating freely from the base (except for some maybe basal taxa with Type III venation) but most of the time being born on the vein R (rarely on the Cu vein). Spines of fore and mid tibiae with variable degree of development, usually modestly developed (Figs.11, 87, 105, 117, 132). Hind femora robust and not too long, only 1.5–2.5 times as long as the pronotum (Figs. 14, 15, 115, 116). Male terminalia with diverse variations (Figs. 16, 17, 18, 19, 70), ovipositor with different degrees of curvature, and in some groups it can curve abruptly upwards (Figs. 83, 91, 92, 120, 131, 144).

Type genus: Gryllacris Serville, 1831.

Included taxa: The tribes: Gryllacridini n. sensu.; Progryllacridini n. trib.; Eremini n. trib.; Ametrini n. trib.; Ametroidini n. trib., Triaenogryllacrae n. group. Ungrouped genera: Niphetogryllacris Karny, 1937.

Comments: As a new grouping is proposed, a novo sensu for this taxon is proposed. This subfamily is the most diverse and widely distributed. According to Karny (1924), this subfamily is likely the most basal one, because of the reduction in wing venation.
