 Length (incl. teg.). – Male 10.5-11.0 mm, female 11.0-12.0 mm.   
 Description. – General colour brown. Head (incl. eyes) (Fig. 53) wider than pronotum. Frons (Fig. 54) with central carina longer than half length of frons; sublateral carinae shorter than central carina at about 1:3; lateral carinae yellow. Carina between eyes brown. Clypeus brown, central carina indistinct. Vertex (Fig. 53) brown, wider at anterior margin than long in middle line about 17:1, with light brown macula in each posterior corner, carinate centrally; occipital margin carinate, piceous. Pronotum narrow, wider at widest part than long in middle line about 13:1; anterior margin carinate. Mesonotum and mesopleura brown or piceous.   
Tegmina (Fig. 55) with costal marginal fascia brown, with a yellow spot near middle, with a very small white spot at outer lower angle of the yellowish spot; apical and inner margins with brown fasciae; disc with 2 transverse fasciae: outer fascia nearly straight and connected with apical fascia near posterior corner, inner fascia forming a ring in middle with central part of the ring white; R1 and R2 with a long common stem; apex round, common stem closed to claval suture. Wings (Fig. 56) rather small, apical margin with a brown fascia, costal and inner marginal fasciae very narrow, brown.  
Legs yellow; fore femora with 2-3 lateral spines; middle femora with 4-5 lateral spines. Abdomen brown or dark brown. Tegula brown or dark brown. Eyes piceous, ocelli rufous.  
 Male genitalia. – Anal segment in dorsal view (Figs. 57, 58) longer than wide at middle about 1.5:1, lateral margin convex, basal margin slightly convex; in profile view with ventral margin convex; anal style set about in middle, close to apex. Aedeagus stout. In dorsal view (Fig. 59), phallobase with dorsal process very long, directed first cephalad then laterad at apex, longer than half length of phallobase in middle line at about 1:2; lateral process shorter than dorsal process at about 1:5, directed laterad at apex. In ventral view, phallobase (Fig. 60) not constricted medially, apex concave medially. In profile view, phallobase (Fig. 61) dilated basally. Genital styles (Fig. 58) longer than wide at middle about 1.7:1.   
 Female genitalia. – Anal segment (Fig. 62) rather small, ventral margin slightly convex; anal style set at middle, apical margin in dorsal view (Fig. 63) almost straight, ventral margin concave, lateral margin almost straight. Gonophysis VIII (Fig. 64) tadpole-shaped, basal part and anterior part in an acute angle. Pregenital sternite (Fig. 65) with anterior margin and ventral margin nearly straight medially. Bursa copulatrix (Fig. 62) second pouch slightly bigger than first pouch.   
 Distribution. – China (Guangxi, Hainan, Hunan, Guizhou, Taiwan); Bengal, Sikkim, India, Japan, Vietnam.   
 Remarks. – This species is similar to E. brevicula, but can be separated from the latter by its shorter sublateral carinae of frons (Fig. 54) and very long dorsal spinose process of the male phallobase (Fig. 59).   
 Host plants. – Silver chain, orange, tea plant, tung, and castoroil plant.
