In appearance, Ecpyrrhorrhoe obliquata is similar to E. exigistria in the brown subterminal area of the wings, as well as in the oblique, dark brown streak on forewing which distinguish them from all other species of the genus. Genitalia characters readily distinguish E. obliquata from other members of the genus in the semi-circular sella with basal half of ventral margin bearing curved spines. It can be best distinguished from E. exigistria by the larger forewing length (forewing length: 10.0-12.0 mm), the more distinct and longer streak of the forewing, in the male genitalia (Fig. 25 View Figures 22–27 ) by the shape of sella, and the weakly sclerotized arms of the bifid juxta, which is without teeth, and in the female genitalia (Fig. 40 View Figures 38–43 ) by the shape of antrum.


(Fig. 8 View Figures 3–12 ). 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. Dorsal side yellow and ventral side white; tegula yellow with brown base. Wings. Forewing length: 10.0-12.0 mm. Forewing pale yellow, basal half of costal band and posterior half of subterminal area brown; stigmata and lines dark brown; antemedial line strongly oblique from 1/5 of costa to 1/2 of 1A, then dentated to 2/5 of posterior margin; orbicular stigma dot-shaped, sometimes indistinct; reniform stigma comma-shaped, thick and straight; an oblique, dark brown streak from posterior end of reniform stigma weakly curved and extended to tornus; postmedial line obliquely outwards from 3/5 of costa to 1/2 of M1, then dentated inwards to 2/3 of posterior margin; terminal line dark brown and intermittent; fringe with basal half yellow and blackish brown, distal half with anterior half yellow and posterior half dark brown. Hindwing pale yellow, subterminal area from dark brown to brown, gradually paler to tornus; postmedial line dark 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, each segment with posterior margin whitish, black on distal end; white ventrally.

Male genitalia

(Fig. 25 View Figures 22–27 ). Uncus with basal 1/3 nearly triangular and naked. Valva with costa nearly straight or concave and ventral margin curved, basal part weakly narrowed, remainder of even width, apex obtusely rounded; sella nearly semi-circular, bearing short and curved spines on distal half of ventral margins; sacculus with middle part inflated into a thumb-shaped protrusion. Juxta with base wide, distal 3/4 bifid into pointed arms. Saccus narrowly triangular. Phallus long and straight, with a bundle of short spines assembling into cone-shape at distal end.

Female genitalia

(Fig. 40 View Figures 38–43 ). Anterior apophysis ~ 2 × length of posterior apophysis. Antrum cup-shaped, with anterior 1/3 strongly sclerotized and covered with spinules on inner wall, posterior 1/3 abruptly broad and partly wrinkled; colliculum long; ductus seminalis connecting to anterior end of colliculum and with a short sclerite located opposite to colliculum; ductus bursae ~ 2.5-3 × as long as diameter of corpus bursae, basal 1/3 bearing a slim sclerite. Corpus bursae globular; rhomboid signum with maximal length approximately 1/2 as long as diameter of corpus bursae; the second (posterior) signum nearly thumb-shaped bearing a wide base, sparsely covered with long spines.
