Diagnosis.

Within the genus, E. rufipicta   resembles E. fimbriata   (Moore, 1886) in having nearly the same forewing length, yellow wings bearing brown markings and an almost indistinct, brown subterminal band (Fig. 9 View Figures 3–12 ). However, it can be differentiated from E. fimbriata   by more dentated and relatively thick postmedial line on both wings, in the male genitalia (Fig. 26 View Figures 22–27 ) by the nearly oval valva, the thumb-shaped dorsal sella, the triangular ventral sella bearing several spines, the longer and strongly sclerotized arms of the juxta, and two long and pointed spines located on anellus.

Redescription

(Fig. 9 View Figures 3–12 ). Head. Frons yellow, with lateral white bands. Vertex pale yellow. Labial palpus yellow, contrastingly white at base ventrally. Maxillary palpus yellow, white terminally. Thorax. Dorsal side yellow, and ventral side white; tegula yellow, with base brown. Wings. Forewing length: 9.0-12.0 mm. Wings yellow, with brown markings. Forewing with costal base brown; antemedial line dentated from 1/4 of costa slightly arched to 1/3 of posterior margin; orbicular stigma oblate; reniform stigma comma-shaped and thick; postmedial line dentated from 3/4 of costa to 2/5 of CuA2, then deeply dentated to 2/3 of posterior margin; subterminal band indistinct, with inner margin crenulated; fringe pale yellow. Hindwing with postmedial line brown, slightly dentated from 2/3 of M1 arched to 1/2 of CuA1, bending inward to basal 1/3 of CuA1, then dentated to near tornus; subterminal line and fringe as in forewing. Abdomen. Pale yellow dorsally, gradually brown to distal part, white ventrally.

Male genitalia

(Fig. 26 View Figures 22–27 ). Uncus with basal 1/2 nearly triangular and naked. Valva with costa slightly convex and ventral margin curved, with basal part narrowed, remainder nearly oval, apex rounded; sella nearly triangular, bearing short spines on distal and inner margins, with a curved, finger-shaped dorsal projection; sacculus with middle part inflated into a triangular and setose protrusion. Juxta with base wide, distal 4/5 forming slender, long, and sclerotized arms dentate apically; anellus with two long and pointed spines (connected with distal arms of juxta in Fig. 26 View Figures 22–27 ). Saccus rounded triangular. Phallus long and straight, cornuti presented as a narrow sclerite with dense and short spines.

Female genitalia

(Fig. 41 View Figures 38–43 ). Anterior apophysis ~ 2.5 × length of posterior apophysis. Antrum cylindrical, tuberculate laterally on anterior end, strongly sclerotized and covered with spinules on inner wall; colliculum long and broad, narrower medially; ductus seminalis connecting to anterior end of colliculum and with a wide sclerite located opposite to colliculum; ductus bursae ~ 2.5-3 × as long as diameter of corpus bursae, basal 2/5 bearing a slim sclerite. Corpus bursae globular; rhomboid signum with maximal length > 1/2 of diameter of corpus bursae; second (posterior) signum composed of a pair of round sclerites bearing dense and long spines.

Distribution.

Remarks.

Based on the substantial morphological similarity in the male genitalia between the types of Asopia rufipicta   Butler, 1880 and Paliga rubicundalis   Warren, 1896, Paliga rubicundalis   is considered as a junior synonym of E. rufipicta   (Butler).
