Subfamily Hemigryllinae Gorochov, 1986 stat rev. Redescription. Medium-size species (body length ranging between 11 and 15 mm). Body covered by fine hairs, making these insects soft to the touch, along with strong setae, mainly on the anterior and posterior margins of the pronotal disc, and the dorsal and ventral margins of the fore and middle legs (Figs. 1, 4, 5, 6, 9, 12). Head rounded in frontal view, eyes positioned in the middle of the head; fastigium two or three times wider than the scape; median and lateral ocelli present (Figs. 2A, 7A, 10A); hypopharinx hairs short. Tympanum ovoid and only present on the inner face of the fore tibia (Figs. 2D, 7D, 10D); hind tibia with strong, long, and articulated apical and subapical spurs, with no spines between them; second segment of the tarsi reduced; last segment of the tarsi of the hind leg noticeably narrowing compared to the first one (Figs. 2F, 7F, 10F). Males. Harp of the stridulatory apparatus crossed by some veins, generally by three or four veins; mirror medium size, which may (Fig. 10H) or may not be divided by a medial vein (Figs. 2H, 7H), without long cell outlined distal part of mirror; chords curved, these veins generally spaced equidistantly; apical area developed (Figs. 2H, 7H, 10H). Genitalia elongated, pseudepiphallic sclerite semi-tubular in shape, narrowing towards the apex, curving ventrally, covering or enclosing various structures, such as the pseudepiphallic paramere; in lateral view, the pseudepiphallic sclerite is subtriangular and curves upward (Figs. 3, 8, 11). Females. Ovipositor very reduced, almost covered by the subgenital plate, valves appear thin, spine-like, and separated but not divergent (Figs. 4C, D, E); spermatheca poorly developed. Taxa included. Only Hemigryllus Saussure, 1877.
