Length (incl. teg.). – male 9.0-10.0 mm, female 11.0-12.0 mm.

Description. – Head (incl. eyes) ( Fig. 40 ) wider than pronotum. Frons ( Fig. 41 ) dark-brown or piceous, sublateral carinae indistinct, shorter than central carina at about 1:3.4; lateral carinae light brown. Carina between eyes light brown. Clypeus yellow, ecarinate. Vertex ( Fig. 40 ) brown, without central carina, wider at anterior margin than long in middle line about 14:1, macula present in posterior corner, light brown; occipital margin carinate, piceous. Pronotum brown, narrow, wider at widest part than long in middle line about 6:1, punctated beside central carina; anterior margin carinate. Mesonotum and mesopleura piceous.

Tegmina ( Fig. 42 ) with costal marginal fascia brown, with a yellow spot near middle; apical margin and inner margin with broad brown fasciae; disc with one transverse brown fascia; common stalk of R1 and R2 longer than basal cell. Wings

( Fig. 43 ) rather small, costal and inner margins with narrow brown fasciae, apical area with a broad, brown fascia.

Legs yellow, median part of hind femora black; fore femora with 2-4 lateral spines; middle femora with 3-5 lateral spines. Tegula brown. Eyes piceous. Ocelli golden.

Male genitalia. – Anal segment in dorsal view ( Figs. 44, 45 ) trapeziform, longer than wide at middle at about 1.4:1, lateral margin slightly convex, apical margin slightly concave, basal margin slightly convex, ventral margin in profile view ( Fig. 44 ) strongly convex; anal style set in middle close to apex. Aedeagus with connective symmetrical. Phallobase ( Fig. 46 ) with dorsal process long, directed cephalad and laterad, longer than half length of phallobase in middle line at about 1:2; lateral process shorter than dorsal process at about 1:3. In ventral view ( Fig. 47 ), phallobase constricted medially; apex concave medially. In profile view ( Fig. 48 ), phallobase dilated basally. Genital styles longer than wide at middle about 2.7:1.

Female genitalia. – Anal segment ( Fig. 49 ) rather small; anal style set beyond middle, in dorsal view ( Fig. 50 ), apical and lateral margin concave, ventral margin straight. Gonophysis VIII ( Fig. 51 ) shoe-shaped, basal part and anterior part in a right angle. Apical teeth of gonophysis VIII normal, not dilated. Median part of pregenital sternite ( Fig. 52 ) with anterior margin nearly straight, ventral margin mesially convex. Bursa copulatrix as in fig. 49.

Distribution. – China (Yunnan, Hunan).

Remarks. – This species is similar to E. facialis Melichar , but can be separated from the latter by its rather long dorsal spinose process of male phallobase ( Fig. 46 ) and its short sublateral carinae of frons ( Fig. 41 ).

Etymology. – The species name is derived from the Latin longus, referring to the long dorsal spinous process of the male phallobase.
