Cimeliomorpha inflata , sp. n.

( Figs. 9 , 22−23 , 33−34, 40, 59−62)

Cydia egregiana ; Laithwaite et al. 1975: 187, fig. 14h [misidentification]

Diagnosis. This species differs from members of the cymbalora group by the yellow basal 2/5 of the forewing and the partially orange hindwing. From other species in the egregiana group it differs by the very distinct but short, black, longitudinal fine striation in the ocelloid patch, and by the orange scales in the hindwing restricted to a bipartite median patch. The valva of C. inflata is unique, with a large and swollen cucullus, and the female genitalia are diagnostic with two elliptical patches of scale sockets on the membranous lamella postvaginalis and a very long colliculum.

Description. Head. Frons, vertex and labial palpus yellow. Labial palpus porrect and rather slender, second segment slightly widened medially, apical segment rather thick ( Fig. 9 ). Antenna light brown, scape, pedicel and basal segments of flagellum yellow, flagellum with few black scales dorsally except on basal segments.

Thorax. Without raised posterior scale tufts, pronotal collar, tegula and mesonotum yellow. Forewing broadly subtriangular, length 9.5−9.6 mm in males (n = 6) ( Fig. 22 ), 9.0−9.1 mm in females (n = 6) ( Fig. 23 ); costa evenly curved, male costal fold absent, termen rather round, weakly concave below apex, basal 2/5 of wing yellow; distal 3/5 of wing with orange brown ground colour, with a broad transverse silvery band along its inner margin, angled near costa, inwardly followed by a narrow, irregular, orange line; with four additional 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 between M 1 and M 2, fourth across apex preceded by a parallel yellow subtriangular mark following a small silvery spot below costa; ocelloid patch a large bean-shaped area of white-tipped orange brown scales producing fine transverse white lines, medially with narrowly subtriangular band of fine longitudinal blackish striation, distally delineated by two convergent silvery streaks, and tornal area with orange brown ground; with 4 large spots of raised silvery scales, an angled series of 3 behind CuA 1 with two distal ones shadowed by black, fourth at anterior angle of the discal cell; with indistinct minute dark brown dots on costa, with well-developed strigulae as black spots alternating with yellow spots along costa; fringe brown. Underside of forewing dark brown, with large yellowish grey patch across 2/5 extending from M-stem to dorsum and a yellowish grey patch at posterior angle of discal cell. Hindwing blackish except for narrow orange band along termen and a narrow bipartite orange patch between middle of discal cell and anal region, interrupted along CuP; fringe brown with dark basal line to near anal angle, then gradually paler to white. Underside of hindwing orange, broad irregular blackish band along termen and anal region and irregular blackish patch medially on costa.

Abdomen. Male genitalia ( Figs. 33−34 , 40 ) with tegumen moderately sclerotised, short and wide, dorsally round with dense scale sockets dorsally, pedunculus with large anterior subtriangular process; uncus absent; socii moderately large, subtriangular, with dense bristles gnathos a moderately sclerotised band; vinculum a moderately long and curved band, moderately sclerotised; juxta rather small, caulis short, phallus moderately long, slightly curve ventrally, ventrodistal point and swollen, with dense cornuti sockets, base surrounded by anellus; membrane next to juxta with numerous short setae; valva with deep emargination at base of cucullus; sacculus large, subtriangular with small subtriangular lobe projecting from angle, with large patch of dense spiniform setae next to basal opening, with moderately dense setae along dorsal margin neck with numerous very short spiniform setae posteriorly; cucullus moderately large, swollen, subtriangular, with rounded cone-shaped apex, outer surface with dense scale sockets, inner surface with dense setae and a spine cluster at apex. Female genitalia ( Figs. 59−62 ) with papillae anales densely setose; tergum VIII with moderately dense scale sockets posteriorly and on lateral triangular extensions; sterigma membranous, two parallel, longitudinal, elliptical patches of dense microtrichiae posterior to small round ostium; sternum VII moderately sclerotised, posterior margin with deep V-shaped emargination containing sterigma, with dense scales sockets especially near posterior margin; colliculum very long, 1/3 length of ductus bursae, strongly sclerotised; ductus bursae long, gradually widening towards corpus bursae, granulate in anterior half; ductus seminalis arising from middle of ductus bursae; corpus bursae rounded, much shorter than length of ductus bursae, with two equal, horn-shaped, nearly straight signa.

Etymology. The specific epithet refers to the swollen appearance of the cucullus (inflata=swollen).

Distribution. Papua New Guinea (St. Matthias Island near New Britain, and Woodlark, Goodenough and Bougainville islands) and Solomon Islands (Guadalcanal and The Nggela Islands).
