Lin , 4-7 Aug.1963 (all in IZCAS except 2 males , 1 female in RMBR ) . Length (incl. teg.). – Male 9.0-10.0 mm, female 10.5-11.5 mm . Description. – Head (incl. eyes) ( Fig. 14 ) wider than pronotum. Frons ( Fig. 15 ) brown, longer than half length of frons; sublateral carinae shorter than central carina at about 1:1.2; lateral carinae brown. Carinae between eyes brown. Clypeus yellow, ecarinate or indistinctly carinate. Vertex ( Fig. 14 ) brown, wider at anterior margin than long in middle line about 15:1, with light brown maculae at each posterior corner; without central carina; occipital margin with a dark carina. Pronotum brown and narrow, wider at widest part than long in middle line about 5.5:1; punctated beside central carina; anterior margin carinate. Mesonotum and mesopleura brown. Tegmina ( Fig. 16 ) with costal marginal fascia brown, with a yellow spot near middle, posterior outer corner of the spot with a rather small white spot; apical margin and inner margin each with a brown fascia; disc with 2 transverse brown fasciae: the outer one nearly straight and connected with apical fascia near posterior corner; the inner one forming a ring in middle, with median part of the ring white; common stalk of R1 and R2 longer than base cell. Wings ( Fig. 17 ) rather small, costal margin and inner margin with narrow brown fascias, apical margin with a broad brown fascia. Legs yellow; fore femora with 2-3 lateral spines; middle femora with 3-4 lateral spines. Abdomen brown. Eyes brown or piceous. Ocelli yellowish. Male genitalia. – Anal segment in dorsal view ( Fig. 18 ) trapeziform, longer than wide at middle about 1.5:1; lateral margin convex, apical margin slightly concave, basal margin slightly convex; ventral margin in profile ( Fig. 19 ) strongly convex; anal style set in middle close to apex. Aedeagus with connective symmetrical. Phallobase ( Fig. 20 ) with dorsal process short, directed first cephalad then laterad at apex, shorter than phallobase in middle line about 1:3; lateral process shorter than dorsal process at about 1:2. In ventral view ( Fig. 21 ), phallobase constricted near base, apex concave medially. In profile view ( Fig. 22 ), phallobase slightly dilated near base. Genital styles longer than wide at middle about 3:1. Female genitalia. – Anal segment ( Fig. 23 ) rather small, ventral margin slightly convex; anal style set beyond middle, in dorsal view ( Fig. 24 ), apical margin slightly concave, ventral margin almost straight, lateral margin convex. Gonophysis VIII ( Fig. 25 ) shoe-shaped, basal part and anterior part in a right angle. Pregenital sternite ( Fig. 26 ) with anterior margin produced forward medially, ventral margin with median portion concave. Distribution. – China ( Fujian , Guangxi , Guangdong ). Remarks. – This species is similar to E. ocellus , but can be separated from the latter by its long sublateral carinae of frons ( Fig. 15 ) and shorter dorsal spinose process of the male phallobase ( Fig. 20 ). Etymology. – The species name is derived from the Latin breviculus , referring to the short dorsal spinous process of the male phallobase.
