 Length (incl. teg.). – Male 9.5-10.5 mm, female 10.5-11.0 mm.   
 Description. – General colour brown. Head (Fig. 1) (including eyes) narrower than pronotum. Frons (Fig. 2) brown; central carina longer than half length of frons; sublateral carinae shorter than central carina at about 1:1.4; lateral carinae light brown; carina between eyes light brown. Clypeus yellow, ecarinate. Vertex yellow, wider at anterior margin than long in middle line at about 1:16, without central carina, posterior corner with light brown macula, occipital margin carinate, brown. Pronotum brown, narrow, wider at widest part than long in middle line about 1:6.5, punctated beside central carina; anterior margin carinate. Mesonotum and mesopleura brown.   
Tegmina (Fig. 3) with costal marginal fascia brown, with a yellow spot near middle; apical and inner margins with brown fasciae; disc with a transverse, brown fascia; common stalk of R1 and R2 longer than base cell. Wings (Fig. 4) small, costal margin and inner margin with narrow, brown fasciae; apical margin with a broad, brown fascia.  
Legs yellowish, fore femora with 3-4 lateral spines; middle coxa with one basal spine; middle femora with 3-5 lateral spines. Abdomen brown or dark brown. Tegula dark brown. Eyes grey. Ocelli golden.  
 Male genitalia. – Anal segment (Figs. 5, 6) large, oblong in dorsal view (Fig. 6), longer than wide at middle at about 1.5:1, lateral margins almost straight, apical margin slightly concave, basal margin strongly convex, ventral margin in profile (Fig. 5) strongly convex; anal style set in middle but close to apex. Aedeagus with connective symmetrical. Phallobase (Fig. 7) with dorsal process short, shorter than half length of phallobase in middle line about 1:3, directed cephalad and laterad; lateral process shorter than dorsal process at about 1:2. In ventral view, phallobase (Fig. 8) constricted medially, apex concave medially. In profile view (Fig. 9), phallobase not dilated near base. Genital styles (Fig. 5) longer than wide at middle about 3.6:1.   
 Female genitalia. – Anal segment (Fig. 10) rather small, ventral margin in profile slightly convex; anal style set beyond middle, in dorsal view (Fig. 11), apical margin concave, ventral margin strongly concave, lateral margins convex. Gonophysis VIII (Fig. 12) shoe-shaped, basal part and anterior part in a right angle, anterior part dilated apically. Pregenital sternite (Fig. 13) with anterior and ventral margins nearly straight medially. Bursa copulatrix as in fig. 10.   
 Distribution. – China (Fujian, Zhejiang, Jiangxi, Henan, Shanxi, Taiwan); Japan.   
 Remarks. – This species is similar to E. longa, new species, but can be separated from the latter by its short spinose process of the male phallobase (Fig. 7) and its long sublateral carinae of the frons (Fig. 2).   
 Host plants. – Silver chain, orange, tea plant, mulberry.
