Differential diagnosis. This species seems to be closely related to X. aliquantula (Karsch) , but differs in having apically flattened, lobe-like cerci in the male. Description. General. Body small, slender; macropterous ( Fig. 6 G). Head. Fastigium of vertex triangular, blunt apically, barely reaching base of scapus, flat dorsally; antennae about twice as long as body; frons flat, vertical; eyes globular, moderately protruding. Thorax. Lateral lobe of pronotum as long as wide; anterior margin of pronotum flat; metazona weakly convex ( Fig. 6 F); posterior edge of metazona narrowly rounded. Legs. Legs slender. Front tibia unarmed dorsally, with 5 spines on posterior and 4 on anterior ventral margin; tympanum bilaterally open; genicular lobes of front femur unarmed; front femur unarmed ventrally. Mid tibia unarmed dorsally; thickened in proximal 3/4, with 5 spines on posterior and 4 on anterior ventral margin; mid femur unarmed ventrally; genicular lobes of mid femur unarmed. Hind femur unarmed ventrally; genicular lobes of hind femur armed on inner side. Wings. Tegmen surpassing apex of hind femur; anterior margin straight; hind wing slightly longer than tegmen. Costal field wide, gradually narrowing towards wing tip, ending at 4/5 of tegmen; veins Sc and R close together, parallel along their entire length; vein Rs branching off before middle of tegmen, with 3 apical branches; right stridulatory area with large, fully developed mirror; left stridulatory area with large, fully developed, roughly rectangular mirror ( Fig. 4 T). Stridulatory file elevated on thickened vein, straight, with 46 teeth, 0.75 mm long, 0.04 mm wide ( Fig. 4J ). Abdomen. Epiproct unmodified, rounded; 10th tergite unmodified. Cercus with vertical rounded lobe on upper surface (Fig. 2E), short, slightly bent inwards; apex strongly flattened laterally (Fig. 2F); paraprocts unmodified; epiphallus not sclerotized. Subgenital plate narrowly trapezoidal; distal end strongly narrowed (Fig. 2D); styli short, strongly flattened laterally, approximately triangular (Fig. 2F), parallel. Coloration. Coloration light green; antennal scapus with dark markings on anterior surface; antennae concolorous; eyes uniformly colored; face without darker markings; occiput with dark band; prozona with darker band, continuous with that on occiput; tegmen without markings; hind wing slightly fumose; genicular lobes of front legs with small, dark patches; hind legs uniformly colored; abdominal sterna and subgenital plate without markings. Measurements ( 1 male ). body w/wings: 22.5; body w/o wings: 12; pronotum: 4; tegmen: 18.5; hind femur: 11 mm .
