Diagnosis. This species differs from members of the egregiana- group by the pure white body and basal part of the fore- and hindwings. It is most similar to C. novarana in forewing pattern, but the inner edge of the blackish hindwing tip is deeply curved rather than straight and angled only below the costa as in C. novarana , and nearly reaches the anal angle. The valva of C. cymbalora is unique with a large cylindrical and distally projecting saccu- lus, a strongly sinuate costa and a transverse elliptical cucullus. The corpus bursae has an inconspicuous granulate signum, and the ductus bursae abruptly widens into the corpus bursae.

Description. Head. Frons and labial palpus white. Labial palpus porrect and rather slender, second segment widened medially, apical segment rather thick ( Fig. 4 ). Antenna light brown, scape and pedicel white, flagellum with few black scales dorsally, with some scattered white scales in basal segments.

Thorax. Pronotal collar, tegulae and mesonotum white, without raised posterior scale tufts. Forewing broadly triangular, length 5.8−5.9 mm in males (n = 6) ( Fig. 10 ), 6.0−6.5 mm in females (n = 2) ( Fig. 11 ); costa evenly curved, male costal fold absent, termen rather rounded but weakly concave below apex; basal 2/5 of wing white; posterior 3/5 with brownish orange ground colour, its inner margin edged by very narrow black line, with a distinct transverse silvery band across middle of wing, angled near costa, with three oblique silvery lines from costa, the first ending in silvery spot at R 4, the second from apical 1/3 of costa to termen between M 1 and M 2, the third across apex, preceded by a parallel yellow band; ocelloid patch a large roundish area of white-tipped brownish orange scales producing fine transverse white lines, with longitudinal blackish striation, scattered with blackish, distally delineated by two convergent silvery streaks; with 4 large spots of raised silvery scales, shadowed by black, an angled series of three behind CuA 1, the fourth at the anterior angle of the discal cell; costa with 6−7 minute, dark brown dots along basal 2/5, with well-developed strigulae as black spots alternating with yellow streaks along apical 3/5 of costa; fringe brown. Underside of forewing dark brown with small yellowish grey spots along costa, with white patch basally, and white transverse band at basal 2/3, extending from Sc to dorsum. Hindwing white, apical part blackish, its inner margin irregular and strongly curved, extending from basal 1/3 costa to anal angle. Fringe light brown to CuA 1, then white; basal line somewhat darker. Underside of hindwing white, with area of blackish scaling as upper part except apical 1/3 of costa interrupted by transverse white patch.

Abdomen. Male genitalia ( Figs. 24 , 35 ) with tegumen moderately sclerotised, short and wide, dorsally round with sparse long setae, pedunculus with large, triangular process; socii broad, subovate, hairy; vinculum a short and wide band; juxta moderately large, caulis short, phallus moderately long, straight, slightly tapering to apex, vesica with numerous spine-shaped cornuti with sockets; valva with large cylindrical and distally projecting sacculus, densely hairy, followed by deep narrow emargination at base of cucullus; costa strongly sinuate; cucullus large, transversely elliptical, densely bristled and ending in a strong spine. Female genitalia ( Figs. 41−43 ) with papillae anales densely setose; tergum VIII with moderately dense scale sockets posteriorly and on lateral triangular extensions; with bipartite patch of scale sockets on membranous lamella postvaginalis; sternum VII weakly sclerotised, posterior margin medially concave, with two small groups of separate dense scale sockets posterolaterally; entrance to ostium a small, shallow, membranous cup behind posterior margin of sternum VII; colliculum small, sclerotised, rather longer than wide; ductus bursae moderately long, narrow throughout, anterior 1/3 granulated, ductus seminalis narrow, arising from middle of ductus bursae; corpus bursae distinct, ovate, shorter than length of ductus bursae, granulated, and with one inconspicuous, slightly concave granulate signum.

Stevens, B.M. 1972−527 ( NHMUK) ; 1♂, Khasi Hills , Jul 1906, B.M. genitalia slide no. 33125 ( NHMUK) .

Distribution. India, Thailand (new record). Specimens from Thailand were collected from evergreen forest.

Comments. Clarke (1958) figured the adult and male genitalia of the lectotype, and David Lees of The Natural History Museum, London, kindly compared detailed genitalia photos of Thai material with the lectotype. Other material from Assam and Khasi Hills also agrees with the Thai specimens. Cimeliomorpha cymbalora and C. novarana were long treated as the same species, as discussed in detail under C. novarana .
