Diagnosis. This species differs from members of the cymbalora group by the yellowish basal half of forewing and mostly orange hindwing. It is similar to C. perspinosa , C. jarujini , and C. inflata in forewing pattern, but the extent of blackish markings on the hindwing separates the four species. In C. egregiana the blackish mark reaches the anal angle and stops there unlike in C. inflata where it ends before reaching the angle or in C. jarujini where it extends along the anal margin. In C. egregiana and C. perspinosa the blackish markings are similar on the upper side, but on the underside there is a blackish longitudinal patch on costa extending to near wing base and weakly connected with black apex only in C. egregiana . The valva of C. egregiana is unique, simple, straight, and with only a shal- low excavation before the cucullus, and the sterigma in the female has a strongly sclerotised spout from its ventral margin and the signa are conspicuously unequal, one with a long scobinate base.

Description. Head: Frons and labial palpus pale yellowish. Labial palpus porrect and rather slender, second segment slightly widened medially, apical segment rather thick ( Fig. 6 ). Antenna light brown, scape, pedicel and basal segments of flagellum yellow, flagellum with few black scales dorsally.

Thorax: Pronotal collar, tegula, and mesonotum yellowish, without raised posterior scale tufts. Forewing broadly subtriangular, length 8.7 mm in male (n = 1) ( Fig. 16 ), 7.2 mm in female (n = 1) ( Fig. 17 ); costa evenly curved, male costal fold absent, termen rather round with slightly notch below apex, basal half of wing yellowish with 8 small dark brown dots along costa; posterior half of wing with brownish orange ground colour, with well-developed strigulae as black spots alternating with yellow spots along costa, with distinct transverse silvery band across middle of wing, angled near costa, its inner margin irregularly edged, black scales followed by an orange band; with four oblique silvery lines from costa, first ending in silvery spot at R 4, second narrow and short extending to R 2, third from 3/4 costa to termen at M 2, fourth across apex preceded by a parallel yellow subtriangular mark; ocelloid patch a large roundish area of fine longitudinal blackish striation on whitish ground, scattered with black dots and distally delineated by two convergent silvery streaks, with 4 large spots of raised silvery scales, shadowed by black and some orange, an angled series of 3 behind CuA 1, fourth at anterior angle of discal cell. Underside of forewing dark brown around margin, with small yellowish grey triangles alternating with black spots along costa, with large orange patch medially, with brown fringe along termen. Hindwing orange with blackish band along edge except in anal area; wing margin edged with narrow orange line, inner margin of blackish band roughly rectangular. Underside of hindwing orange, blackish margin roughly as on upper surface, with blackish longitudinal patch on costa extending to near wing base and weakly connected with black apex, fringe brownish grey to M 3, then orange.

Abdomen. Male genitalia ( Figs. 27−28 , 37 ) with tegumen moderately sclerotised, short and wide, dorsally round with dense setae, pedunculus with large anterior triangular process, lightly sclerotised; socii narrowly ovate, hairy; vinculum short and wide band; juxta rather small, caulis short, phallus moderately long, slender, with curved ventrodistal point; membrane next to juxta with numerous short setae; valva straight and simple, with only shallow ventromedial emargination, with large basal opening, sacculus with dense setae along margin, cucullus wide, broadly elliptical, moderately setose, with small upcurved triangular point in middle of ventral margin, and round- ed apex. Female genitalia ( Figs. 49−51 ) with papillae anales densely setose; tergum VIII with moderately dense scale sockets posteriorly, and very dense on lateral triangular extensions; sterigma a lightly sclerotised plate with a strongly sclerotised, small, tongue- to gutter-shaped anterior projection, with dense microtrichia and moderately dense scale sockets ventrolaterally, on posterolateral extensions patch of moderately dense scale sockets; sternum VII weakly sclerotised, posterior margin weakly concave, with very dense scales sockets near posterior margin; sterigma sclerotised forming subcircular patch, posterior part extending divert, oblique outwardly, with dense micro- trichiae surrounding small ostium bursae especially beyond ostium posteriorly and moderately dense scale sockets along margin; antrum small, rather short, anterior part forming subtriangular, strongly sclerotised, colliculum rather short, weakly sclerotised; ductus bursae very narrow, widening and granulate approaching corpus bursae; ductus seminalis arising from near entrance of corpus bursae; corpus bursae large, longer than ductus bursae, granulate, with two horn-shaped signa with unequal scobinate bases, one much longer and larger than the other.

Holotype. ♀ ( NHMUK), ‘Doleschal 1859. Amboina’, ‘Novara CXXXIX. f 40. Grapholitha egregiana n. Ambon ♀ ’, ‘ Felder Coll. Rothschild 1913-86 ’, ‘FELDER’S TYPE’, ‘609’. ‘B.M. genitalia slide No. 11771’, ‘ NHMUK 010921397 ’.

Specimens examined. Indonesia: 1♂, Amboyna, Doherty, 1892 , no. 41344, Walsingham Collection 1910−427, B.M. genitalia slide no. 33121 ( NHMUK) , 1♀, Amboyna, Doherty, 1892 , no. 41343, Walsingham Collection 1910−427, B.M. genitalia slide no. 33120 ( NHMUK) .

Distribution. Ambon Island ( Maluku Islands), Indonesia.

Comments. The hindwing pattern is distinct in all Cimeliomorpha species, except in C. egregiana and C. perspinosa , but the distributions of the latter two are widely separated, and their genitalia are very different. The figure in ‘Die Reise der Oesterreichischen Fregatte Novara um die Erde’ agrees with the other specimens from Ambon studied for this revision, with the black band reaching the anal angle in the hindwing and stopping there ( Fig. 1 ).
