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.
