DIAGNOSIS

Among the Philippines Glaucocharis species, Glaucocharis kayumanggi sp. n., G. sungay sp. n., and G. negrosensis sp. n. are easily distinguished by the general brown color of the forewing in female specimens, while other species exhibit a mix of white, fulvous, and brown scales. Glaucocharis kayumanggi sp. n. can only be confidently separated from G. sungay sp. n. and G. negrosensis sp. n. by examination of genitalia. In male genitalia ( Fig. 83 ), this species shares with G. sungay sp. n. and G. negrosensis sp. n. the club-shaped gnathos apex, the ventro-basal hook-shaped process of the valva, and the long, narrow, sclerotized phallus. In G. kayumanggi sp. n., the hook-like ventral process of the valva is thinner than in G. sungay sp. n. and longer than that of G. negrosensis sp. n., almost reaching valval dorsal margin. The sacculus apex splits in two, with the dorsal arm extending beyond ventral process distally and ventrally forming a conspicuous lobe. In female genitalia ( Fig. 141 ), the oblong corpus bursae with the star-like signum separates this species and G. sungay sp. n. from all Glaucocharis species (female of G. negrosensis sp. n. not known). The triangular indentation of the antrum ventral margin best separates this species from G. sungay sp. n., where the antrum margin is evenly rounded.

HABITUS ( FIGS. 25, 26 )

Forewing length 5.4-6.4 mm (n = 6). Male forewing ( Fig. 26 ) with pale yellow ground color, suffused with brown scales. Antemedian line originating at costal 1/3, arched outwardly, then bent inwards towards dorsum, meeting dorsum at right angles, cream. Distal discoidal stigma forming short transversal dark brown streak. Postmedian line originating at costal 3/4, broadly arched outwards, jagged at CuA2 vein, meeting dorsum with an angle of 80°, cream. Subapical V-shaped cream streak. Subterminal area speckled with dark brown. Margin with six black spots, the three near tornus more conspicuously marked. Fringes metallic brown. Hindwing white. Female forewing ( Fig. 25 ) with metallic brown ground color. Antemedian line curved in costal half, then bent inwards towards dorsum, cream, distally edged with darker brown. Median area uniformly metallic brown, small fulvous blotch at costa. Distal discoidal stigma forming short transverse fulvous streak. Postmedian line conspicuously arched outwards towards margin, wavy, basally and distally edged with dark brown. Apex fuscous with thin metallic streak. Subterminal area brown to copper, with darker spots. Fringes metallic brown, white apically, cream at margin notch. Hindwing pale yellow, apex metallic brown.

MALE GENITALIA ( FIG. 83 )

Uncus about 4/5 of tegumen arm length, slender; lateral margin projecting downwards into a tooth at basal 1/4, uncus conspicuously narrowed at 3/4; apex duck-beak shaped. Gnathos arms joining at basal 1/4, gnathos projection as long as uncus, slender, apex club-shaped, covered with small teeth, densely haired. Valva with ventro-distal process hook-shaped, pointing upwards, strongly sclerotized; sacculus split in two: ventral arm slender with subtriangular apex; dorsal arm more strongly sclerotized, dorsal margin straight, ventral margin forming a conspicuous rounded bump, apex reaching beyond ventral hook-shaped projection, rounded, pointing downwards. Juxta with ventral keel-like projection at base; juxta plate enlarging in basal half, abruptly narrowed at midlength, distal projection narrow, apex tongue-shaped. Phallus long, thin, sclerotized, vesica devoid of cornuti.

FEMALE GENITALIA ( FIG. 141 )

Posterior apophyses ca 2.2 X length of tergite VIII. Intersegmental membrane VIII-IX ca 1.3 X length of tergite VIII. Anterior apophyses ca 2 X length of tergite VIII. Antrum funnel-shaped, ventral posterior margin V-shaped, strongly sclerotized. Antrum-colliculum junction marked, short, membranous. Colliculum narrow, ca 1/10 of ductus length, incurved, sclerotized. Ductus bursae long, roughly straight. Ductus seminalis branching at corpus opening. Corpus bursae oblong, roughly as long as ductus bursae, scobinate, with well-marked star-like signum near corpus opening.

ETYMOLOGY

From the Tagalog kayumanggi , brown, refering to the brownish color of the forewings of the females.
