Diagnosis.
This species is similar to E. obliquata but can be best distinguished from it by the smaller size (forewing length: 7.0-9.0 mm), the pale brown reniform stigma and the indistinct and short streak of the forewing (Fig. 14 View Figures 13–21 ), in the male genitalia (Fig. 30 View Figures 28–33 ) by the excurved, finger-shaped and setose sella, the strongly sclerotized arms of the juxta, and anellus with a long spine and one or two short spines and in the female genitalia (Fig. 45 View Figures 44–49 ) by the mostly tubular antrum.
Description
(Fig. 14 View Figures 13–21 ). Head. Frons and vertex yellow, frons with lateral white bands. Labial palpus yellowish brown, contrastingly white at base ventrally. Maxillary palpus yellowish brown, white terminally. Thorax. Dorsally yellow, ventrally white; tegula yellow with brown base. Wings. Forewing length: 7.0-9.0 mm. Forewing pale yellow, posterior half of subterminal area brown; antemedial line dark brown, almost straight from 1/5 of costa to 2/5 posterior margin, slightly dentate; reniform stigma comma-shaped, brown; an oblique, dark brown streak from posterior end of reniform stigma, fuzzy, extended to tornus; postmedial line black brown, obliquely outwards from 3/5 of costa to 1/2 of M1, then dentated inwards to 2/3 of posterior margin; terminal line black brown; fringe with basal half brown, distal half dark brown. Hindwing pale yellow, subterminal area from dark brown to yellow, gradually paler to tornus; postmedial line black-brown, slightly dentate from 2/3 of M1 to 1/2 of CuA1, then bending inwards to base of CuA1, finally undulated to 2/3 of posterior margin; terminal line and fringe as in forewing. Abdomen. Pale yellow dorsally, black distally, white ventrally.
Male genitalia
(Fig. 30 View Figures 28–33 ). Uncus with basal 2/5 nearly triangular and naked. Valva narrowly oval, costa straight or slightly concave and ventral margin curved, with apex rounded; sella excurved, thumb-shaped, thick, and setose, bearing thick setae on distal half; sacculus with distal 3/5 inflated into a broad and nearly triangular protrusion. Juxta with base wide, distal 3/4 bifid into slender, curved, sclerotized, and widely separated arms; anellus with a long spine and one or two short spines (attached to distal part of juxta in Fig. 30 View Figures 28–33 ). Saccus rounded triangular. Phallus long and tapering, distal end spinulose and weakly sclerotized, with interlaced spicules cluster on vesica.
Female genitalia
(Fig. 45 View Figures 44–49 ). Anterior apophysis ~ 1.5 × length of posterior apophysis. Antrum long tubular and sclerotized, with anterior 1/3 broad, weakly sclerotized and wrinkled medially; colliculum long; ductus seminalis connecting to anterior end of colliculum and with a weak sclerite located opposite to colliculum; ductus bursae ~ 2-2.5 × as long as diameter of corpus bursae, basal 1/3 bearing a slim sclerite. Corpus bursae globular; rhomboid signum with maximal length> 1/2 of diameter of corpus bursae; second (posterior) signum curved, oval, bearing sparse and long spines.

China (Guangxi, Hainan, Jiangxi, Tibet, Yunnan).
Etymology.
The specific name is derived from the Latin exigu - (= short) and stria (= streak), referring to the short streak on forewings.
