MATERIAL
Holotype: ♂ (specimen identifier coll.mfn-berlin.de_u_d58c00, DNA voucher MFNLEP-PYRALPHIL01-H07, genitalia on slide TL967♂; BOLD sample ID PYPHI378-23). PHILIPPINES: Mindoro: Occidental Mindoro, Mount Baco Pass, 1150 m, 14.01.1998 (W. Mey, V. Samarita). Deposited in MfN.
Paratypes: 1 ♂ (specimen identifier coll.mfn-berlin.de_u_29f992), 10 ♀ (specimen identifiers: MfN: coll.mfn-berlin.de_u_2899da, bb43cb, bef944, 7946ab, 426cd2, 495315, 99a7b7, c3967f, e754a7; PNM: id.bioseasia.org_u_023875) (detailed information in Table S1; https://doi.org/10.5061/dryad.b8gtht7mh).
SIMILAR SPECIES
Eudonia homogenes (Meyrick, 1894).
DIAGNOSIS
Eudonia penicula sp. n. resembles Eudonia homogenes (Meyrick, 1894), from which it can be confidently separated by examination of the genitalia. In the Philippines, this species is separated from Eudonia barbipennis (Hampson, 1897) by the distinctive proximal discoidal and cubital dark brown streaks on the forewing. In male genitalia, the thick setae on the innerside of the valva as well as the thick bristles on the apex of the juxta unambiguously separates this species from E. homogenes. In female genitalia, the antrum is covered with tiny sclerotized spicules as in E. homogenes, but it forms a pouch well delimited from the colliculum in E. penicula sp. n. and is cone-shaped, gradually enlarging torward opening in E. homogenes. Furthermore, the colliculum forms a sclerotized ring about 4/5 of the length of tergite VIII, while it is three to four times the length of tergite VIII and is only weakly sclerotized in E. homogenes.
HABITUS (FIG. 15)
Forewing length 7.2-8.0 mm (n = 5), ground color grey. Basal area with marked dark brown dash. Antemedian line white, running from costal 1/4 to dorsal 1/3, arched outwards. Median area speckled with white scales; marked cubital, proximal discoidal, and distal discoidal thick dark brown ticks. Postmedian and subterminal lines thin, white, forming X-shaped pattern. Margin white. Fringe dirty white, medially with grey line. Hindwing grey.
MALE GENITALIA (FIG. 72)
Uncus 3/4 X tegumen arm length, quadriangular, about twice as long as wide, densely setose; apex broad, truncate. Gnathos projection about 0.5 X uncus length, tubular, curved upwards, dorsal edge dentate, tip rounded. Valva dorsal margin slightly convex, protruding distally into a pointed apex; ventral margin almost straight, curved upwards on distal 1/4; hump bearing patch of thick setae pointed inwards at midlength of innerside of valva. Juxta with base rounded, narrowing from basal 1/4 to 3/4, apex lightly sclerotized, covered with thick bristles. Phallus sclerotized, basal end conspicuously curved, apex with rows of short teeth.
FEMALE GENITALIA (FIG. 133)
Antrum forming broad pouch densely covered with tiny sclerotized spicules, forming a U-shaped indentation in ventral view. Colliculum 4/5 X length of tergite VIII, forming sclerotized ring. Ductus bursae ca 4 X length of corpus bursae, straight, narrow. Corpus bursae globular, with large rounded sclerotized patch.
DISTRIBUTION
PHILIPPINES: Luzon (Benguet, Ifugao, Mountain Province), Mindoro (Oriental Mindoro). Collected at altitudes between 1150 and 2300 m.
DNA BARCODING
The species delimitation analysis recovered two MOTUs, one for specimens from Luzon and Mindoro and one single specimen from Mindanao. The maximum intraspecific p-distance of 2.9% is found between specimens MFNLEP-PYRALPHIL01-D03 from Luzon Mountain and MFNLEP-PYRALPHIL09-E01 from Mindanao. Unfortunately, the abdomen of the Mindanao specimen was lost during the DNA extraction.
ETYMOLOGY
From the Latin peniculus, i: brush, referring to the brushlike appendices in male genitalia.
REMARKS
Nuss (1998) reports Eudonia homogenes from the Philippines. He probably refers to this species, which is externally similar to E. homogenes.
