Figs. 1 F, 2G–I, 3G, 4N–O, 5K–L, 7E–G, 8D–F
Holotype (male): Malaysia: Kedah, near Jitra [6°16'N, 100°25'E], 7.iv.1928, leg. H.M. Pendlebury, depository: The Natural History Museum London (BMNH).
Paratype: 1 female, same locality as holotype, 4.iv.1928, leg. H.M. Pendlebury (BMNH).
Diagnosis. The arrangement of three large and some small teeth on the stridulatory vein agrees with the situation in E. rosea and E. kutu. E. jitra differs from E. rosea by the cerci being more strongly curved and mainly in middle of length as in E. kutu but the apical spine is narrower than in the latter. The pair of large elongate phallus sclerites has the serration on the concave side while in all other species of the subgenus it is on the convex side of the sclerites. The female is characterised by the small tuberculate projection of the gonangulum of ovipositor.
Description. Fastigium verticis narrow with approaching lateral margins, little widening again before tip, faintly furrowed at base; separated from fastigium frontis by a gap. Pronotum narrow; disc with concave fore and convex hind margin; with medial carina in anterior area to principle transverse sulcus and again before hind margin; paranota much longer than high; humeral sinus distinct. Tegmen narrow; maximal width near base behind stridulatory area 3.5 mm; afterwards 2.5–3.0 mm; radius sector rising at end of basal third (Fig. 1 F).
Male. Stridulatory area of tegmen small [broken off in type, clued on cardboard] (Figs. 2 G–I). Stridulatory file on underside of left tegmen little angular, 0.85 mm long, with 2 large teeth in basal half and 10 smaller teeth of decreasing size in apical half; third tooth standing at angle (Fig. 3 G). Mirror damaged by pin (Fig. 2 H). Tenth abdominal tergite with apical margin truncate. Epiproct triangular with medial furrow, at apex with narrow ligulate membranous extension, in lateral view tub-shaped, arising from ventral surface. Cerci strongly curved, with sharp apical tooth (Fig. 4 N–O). Subgenital plate after little more than basal third forming a narrow, straight apical projection with apical third little curved up and apical quarter split into two lobes (Figs. 5 K–L). With a pair of elongate, moderately curved phallus sclerites in prolongation of long membranous lobes; concave margin of sclerites serrate; a small, unpaired central sclerite at base of lobes has the dorsal margin serrate (Figs. 7 E–G).
Female. Tenth abdominal tergite with apical margin subtruncate. Epiproct narrow, in circa basal half with weak medial furrow. Cerci curved, apex pointing. Subgenital plate with approaching lateral margins, with fine medial carina; apico-lateral angles prolonged into an acute-angular process of nearly same length as basal area; in middle of apical margin with a faint obtuse projection (Figs. 8 D–E). Ovipositor strongly curved at base, otherwise nearly straight; margins only at apex with a few hardly visible denticles (Fig. 8 F); gonangulum with a small tuberculate projection.
Coloration. Brown, probably green when alive. Pronotum with black dots except in ventral area of paranota. Tegmen in the large cells behind radius with a single or few black dots, behind radius sector with few black dots, and behind cubitus filled with black dots.
Measurements (1 male, 1 female). Body w/wings: male 35, female 44; body w/o wings: male 16, female 23; pronotum: male 4.1, female 4.5; tegmen: male 27, female 34; tegmen width: male 2.9, female 3.7; hind wing: male 30, female 38; hind femur: male 22, female 27; ovipositor: female 9.5 mm.
Etymology. Named after the type locality; noun in apposition.
