Male. Body smaller than medium species of Gryllinae (Fig. 7A, B). In frontal view, head laterally widened and dorsoventrally short, and vertex broad and flat (Fig. 9B). In dorsal view, head longer than pronotum; occiput widened and slightly convex; vertex inclined; and frons somewhat convex, wide and slightly wider than antennal scape. Antennal scape transverse, shield-like. Epistomal suture shallow, sinuate and medially upward convex. Lower portion of clypeus and labrum depressed. Labrum broad with lateral margins rounded convex and apically arched. End section of maxillary palpus obviously longer than the third; end section of labial palpus conspicuously longer than the total length of remainder two. Pronotum transverse and slightly longer than the half width. Disc of pronotum broad and flattened, anteriorly concave and posteriorly straight, and lateral margin straight and inclined down. Lateral lobes of pronotum broad and flattened with ventral surface slightly inwardly concave. Tegmina very short and not reaching abdominal tip. Tegminal disc broad and flattened, almost rectangular-shaped, slightly arched laterally and pointed rounded apically. Basal field short and slightly longer than 1/3 length of pronotum. Oblique veins two; diagonal vein weakly arched and smoothly jointing with outside margin of mirror. Mirror transverse, somewhat shaped as rhombus with inner and bottom corner rounded. Dividing vein separating a small oval at mirror bottom. Apical field distally straight, very short and shorter than 1/3 length of mirror. Cercus thin and tapering. Outer tympana large and long oval-like; inner tympana very small and oval-like. Hind femur slightly longer than tibia. Subapical spurs six pairs and proximally possessing an additional small one outside. Hind tarsus armed with two rows of spines and numbered more outside. Body colored dark brown dorsally and yellowish-brown ventrally. Occiput ornamented with six yellowishbrown stripes (Fig. 9B). Of them, the outermost ones inclined outward and jointing with yellowish-brown stripes above eyes. Yellowish-brown ornamented above eyes or around ocelli. Occiput, vertex, top portions of frons and inner margin of antennal socket dark brown. Eyes and portions between antennal socket and labrum, including mandible, maxillary and labial palpi yellowish-brown. Pronotum dark brown dorsally and only ornamented with few of yellowish-brown spot laterally. Lateral lobes of pronotum colored yellowish-brown at half lower portions. Elytra yellowish brown with lateral lobes colored dark.Abdomen colored dark brown dorsally and laterally, and yellowishbrown ventrally. Subgenital plate brown. Legs yellowish-brown and ornamented with few of brown spots. Epiphallus transverse (Fig. 8A–C), median lobe weakly convex and truncate apically; lateral lobes short and obtuse, in dorsal view, gap between them large and rectangular-like. Ectoparamere prismatoidal, proximally branched with outside branch thick and inner one thin, and combined as one apically. Female. Body form and coloration similar with male (Figs. 7C, D; 9A). Brachypterous individual armed with elytra bud-like (Fig. 7C). Ovipositor (Fig. 4A, C) yellowish-brown. Etymology. The name refers to its elytra armed with straight margin apically. Remarks. Inner tympana varied, sometimes pit-like and without tympanic membrane and sometimes with a very small tympanic membrane. This species possesses straight apical end of elytra.
