SIMILAR SPECIES

Glaucocharis melistoma (Meyrick, 1931) ; Glaucocharis furculella Wang & Sung, 1988 ; Glaucocharis reniella Wang & Sung, 1988 ; Glaucocharis tridentata Li & Li, 2012 ; Glaucocharis unipunctalis Sasaki, 2007 .

DIAGNOSIS

The general dark brown pattern of the forewing ( Fig. 24 ), the regularly arched antemedian line, and the b-shaped stigma separate this species from other Glaucocharis from the Philippines. With the above listed species, this species shares similar male genitalia ( Fig. 82 ): The gnathos projection is spatulate, covered with a patch of hairs, the valva is distally narrowed, projecting upwards, and the costal process forms a thin basal arm projecting upwards. The short uncus and the S-shaped basal arm of the valva unambiguously separates this species from other Glaucocharis species. In female genitalia ( Fig. 140 ), the membranous antrum, the tubular sclerotized colliculum, and the spherical corpus bursae with one single signum separates this species from other Glaucocharis species.

HABITUS ( FIG. 24 )

Forewing length 4 mm; ground color dark brown. Antemedian line evenly arched, cream. Broad ocher suffusion at costa in basal half, with a mix of cream and brown scales in distal half. Median area scattered with cream scales, cubital area with patch of ocher scales. Postmedian stigma forming b-shaped cream dash filled with ocher. Postmedian line barely marked at costa, zigzagging near margin on middle, then meeting dorsum at 4/5. Apical ocher blotch with cream streak. Margin ocher, interspersed with two dark brown spots. Hindwing dirty white.

MALE GENITALIA ( FIG. 82 )

Uncus ca half as long as tegumen arm, triangular, with apex rounded. Gnathos projection twice as long as uncus, slen-der, apex larger, spatula-shaped, with patch of sclerotized spines surrounded with hairs. Valva with costal arm projected upwards, bent at 2/5 outwards with 75° angle, then bent upwards at 4/5; valva subtriangular in basal 2/3, distal 1/3 projecting upwards into slender arm with rounded tip. Juxta basally rounded, distally forming two arms surrounding phallus. Phallus long, sclerotized, slender.

FEMALE GENITALIA ( FIG. 140 )

Papillae anales missing in the specimen investigated. Anterior apophyses ca 2.2 X length of tergite VIII. Antrum membranous. Colliculum ca half of ductus bursae length, tubular, lightly sclerotized. Ductus bursae long, narrowed medially, conspicuously enlarged on distal 1/4 at ductus seminalis connection. Corpus bursae globular, scobinate, with one rounded signum.

DISTRIBUTION

PHILIPPINES: Mindanao (Davao Oriental), Negros, Samar. Collected at altitudes between 150 and 1050 m.

DNA BARCODING

The two samples MFNLEP-PYRALPHIL07-C10 from Negros and MFNLEP999 from Samar shows identical DNA barcodes.

ETYMOLOGY

From “uncus” and the diminutive Latin suffix “– ellus ”, referring to the short-sized uncus in male genitalia.
