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.
