MATERIAL

Lectotype: ♂ (specimen identifier NHMUK013696725 , genitalia on slide PyralidaeNHMUK Slide N° 3617). “ Gunung Ijau , Mal[aysia]. Pen[insula]” ( NHMUK). Lectotype designated by M. Nuss .

Other specimens examined: 5 ♂, 10 ♀ (detailed information in Table S1; https://doi.org/10.5061/dryad.b8gtht7mh) .

DIAGNOSIS

The dark brown ground color of the forewing ( Fig. 16 ) with the distal discoidal white patches and the postmedian white X separate Eudonia barbipennis (Hampson, 1897) from other Eudonia species encountered in South-East Asia. In male genitalia ( Fig. 73 ), the uncus apex is duck-beak-shaped, while it is bifid in E. barbipennis sp. n., and the gnathos forms a projection about ¼ of uncus length, while the gnathos projection is reduced to a bump in E. barbipennis sp. n. In female genitalia, the lightly sclerotized anterior half of the ductus bursae as well as the pouch at corpus opening covered with sclerotized spinules separates this species from E. penicula sp. n. Female genitalia of E. barbipennis sp. n. were not investigated.

REDESCRIPTION

HABITUS ( FIG. 16 )

Forewing length: 8.2-9.5 mm (n = 5); ground color dark brown, with snow white markings. Antemedian line wavy, white. Median area with two well marked distal discoidal rounded white patches. Postmedian line forming at costa and dorsum well-marked patches, forming with subterminal line a X shape. Subterminal line ill-defined, forming well-marked white spot between R5 and M1 and two smaller blotches between CuA1 and CuA2. Margin with white lunules. Fringe chequered dirty white and brown. Hindwing white; in males, presence of an androconial organ on the dorsum of the hindwing.

MALE GENITALIA ( FIG. 73 )

Uncus 4/5 X tegumen arm length, large, densely haired dorso-apically, apex duck-beak-shaped. Gnathos projection about ¼ of uncus length, slender, with apex rounded. Valva dorsal margin basally concave, medially conspicuously convex, apex pointed. Juxta broad, lanceolate, weakly sclerotized. Phallus slender, curvy, vesica without cornuti.

FEMALE GENITALIA ( FIG. 134 )

Antrum membranous, spinulose. Colliculum 6.8 X length of tergite VIII, narrow, lightly sclerotized. Ductus bursae 5.3 X length of tergite VIII, straight, narrow. Corpus bursae small, globular, membranous, with pouch-like projection at corpus opening bearing sclerotized spinules. One signum at corpus opening.

DISTRIBUTION

PHILIPPINES: Luzon (Benguet, Ifugao, Mountain Province). Collected at altitudes between 2000 and 2350 m.

DNA BARCODING

The species delimitation analysis recovered two MOTUs, one for the specimens from North Luzon and one for the specimens from Negros. A maximum intraspecific p-distance of 5.5% is found between specimens MFNLEP-PYRALPHIL07-C06 from Luzon (Benguet) and MFN-LEP1165 from Negros.
