Other material: 4 unsexed (detailed information in Table S1; https://doi.org/10.5061/dryad.b8gtht7mh).
DIAGNOSIS
Scoparia luzonensis sp. n. is best identified by examination of the genitalia: the long and slender uncus with narrow spatulate apex as well as the row of tiny cornuti on the vesica in male genitalia (Fig. 61) and the pouch at base of ductus bursae in female genitalia (Fig. 123) are unique to this species.
HABITUS (FIG. 05)
Forewing length 5.5-6.0 mm (males, n = 2), 5.5-6.5 mm (females, n = 6); relatively narrow, ground color black, markings white. Basal area sprinkled with white scales. Antemedian line white, running from costal 1/5 to dorsum 1/ 3, broadly arched. Median discoidal spot X-shaped, forming with cubital and dorsal markings with ill-defined white patch; distally with two marked blotches. Postmedian and subterminal lines meeting near costa, forming X-shaped pattern. Margin with 6-7 white spots. Fringe dirty white, with thin dark brown line medially. Hindwing dirty white.
MALE GENITALIA (FIG. 61)
Uncus 1.6 X tegumen arm length, narrowing in basal half, slender on distal half, laterally setose, apex spatulate. Gnathos projection ca ¾ X uncus length, dorso-apically with small teeth, apex tip pointing downwards. Valva dorsal margin convex, sclerotized; ventral process marked; apex rounded. Juxta with rounded base, apex conspicuously indented. Vesica with about 14 tiny cornuti displayed in a row, with a group of three cornuti apart.
FEMALE GENITALIA (FIG. 123)
Antrum membranous. Colliculum 3.5 X length of tergite VIII, lightly sclerotized. Ductus bursae 9-10 X length of tergite VIII, forming at base a membranous pouch, sinuate, narrow, enlarging towards corpus opening on distal ¼. Corpus bursae globular. Signum absent.
DISTRIBUTION
PHILIPPINES: Luzon (Ifugao, Laguna, Mountain Province), Mindoro. Collected at altitudes between 650 and 2100 m
DNA BARCODING
The specimen with identifier coll.mfn-berlin.de_u_2123f8 from Mount Banahaw differs from the other specimens of North Luzon by 1.9-2.5%. This male specimen shows slight differences on the vesica: a subgroup of cornuti is observed in the specimen from the Laguna. A maximum intraspecific p-distance of 3.2% is found between samples MFNLEP-PYRALPHIL01-E09 from Luzon (Ifugao) and MFNLEP-PYRALPHIL01-H08 from Mindoro.
ETYMOLOGY
Referring to Luzon, where the species is predominantly encountered.
