MATERIAL
Holotype: ♂ (specimen identifier coll.mfn-berlin.de_u_693863, DNA voucher MFNLEP999, genitalia on slide TL1310♂; BOLD sample ID PYPHI354-22, Genbank Accession Number PP197031). PHILIPPINES: Samar, Concord Cadacan, 150 m, 22-24.04.1997 (W. Mey, W. Speidel). Deposited in MfN
Paratypes: 1 ♂ (specimen identifier coll.mfn-berlin.de_u_5e4759), 1 ♀ (specimen identifier coll.mfn-berlin.de_u_343871) (see detailed information on Table S1; https://doi.org/10.5061/dryad.b8gtht7mh).
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.
