Eugryllacris: Karny, 1937 . Orthoptera Fam. View in CoL Gryllacrididae, Subfamiliae Omnes View in CoL , 206: 151; Otte, 2000. Orthoptera View in CoL species file 8: Gryllacrididae View in CoL , Stenopelmatidae View in CoL , Cooloolidae View in CoL , Schizodactylidae View in CoL , Anastostomatidae, and Rhaphidophoridae View in CoL , 13; Kim et al. 2014. Zootaxa, 3900(1): 96.
Type species: Eugryllacris ruficeps (Serville, 1831) .
Generic diagnosis. Body medium for Gryllacridinae , form robust. Head with fastigium verticis broad. Eyes prominent; median and lateral ocelli conspicuous. Tegmina and hind wings developed, considerably surpassing the apex of abdomen; M vein of tegmina not united with R vein, nearly parallel. Fore coxae with a small spine. Fore and middle femora unarmed on ventral surface; hind femora with small ventral spines. Fore and middle tibiae with 5 pair of spines, including one pair of apical spines, dorsal surface of middle tibiae with 1 small inner apical spine; dorsal surface of hind tibiae with 2 rows of developed spines, 1 pair of dorsal apical spines and 2 pairs of ventral apical spines. Abdominal stridulatory area with 1 oblique row of pegs on second abdominal tergite; third abdominal tergite with 2 widely separated parallel rows. Male. Ninth abdominal tergite roundly convex, the posterior area obviously curved ventrad, divided in midline forming a pair of lobes, each lobe bearing 1 small apical hook, which directing inwards and slightly downwards. Cerci elongate, conical. Subgenital plate of species distinctive, with well developed styli. Female. Ovipositor as long as body, sickle-shaped, upcurved, its dorsal apices obliquely truncate. Posterior margin of seventh abdominal sternite with 1 small process or broad lobe, reaching the basal or middle area of subgenital plate, which directing backwards or backwards and slightly curved dorsad; its apex obtusely rounded or slightly concave in the middle. Subgenital plate with base broad, narrowing, posterior margin with 1 median concavity.
Discussion. Eugryllacris japonica (Katsumura & Shiraki, 1908) was only recorded by Jin & Xia (1994) in index-catalogeue format, but in the following works ( Liu & Zhang, 2001; Bian et al., 2014) we did not find the noted specimens information and excluded the species from this study. Also, we did not have the opportunity to examine the known species of Prosopogryllacris to compare with Eugryllacris .
