SIMILAR SPECIES

Scoparia ifugaoensis sp. n.

DIAGNOSIS

The conspicuous copper-colored subterminal area of the forewing (Fig. 14) separates Scoparia aenea sp. n. from congeneric species. Scoparia aenea sp. n. is distinctly larger than other species of the spadix group with copper markings. Male genitalia are similar to those of S. ifugaoensis sp. n., but the three small thorn-shaped cornuti are of equal size in S. aenea sp. n., while one cornutus is larger than the other two in S. ifugaoensis sp. n. The female genitalia are very similar to those of S. ifugaoensis sp. n., but the corpus bursae is more markedly globular in S. aenea sp. n. which is rather egg-shaped in S. ifugaoensis sp. n.

HABITUS (FIG. 14)

Forewing length = 6.5-7.5 mm (n = 4); ground color dark brown, with snow white and copper markings. Antemedian band ocher, edged basally and distally with snow white lines. Median area dark brown, medially with large ill-defined white band originating at cell, running down to dorsum. Two distal discoidal copper patches, distally abutted with white mark. Postmedian and subterminal lines meeting at midlength, forming a “X” shape, white. Subterminal area copper-colored. Margin with 6-7 white spots. Fringe basally striped dirty white and grey, distally greyish. Hindwings dirty white.

MALE GENITALIA ( FIG. 71 )

Uncus roughly half of tegumen arm length, triangular, latero-apically setose, apex pointed. Gnathos projection 1.4 X uncus length, slightly curved downwards. Valva dorsal margin conspicuously convex, ventral process marked, valva apex broadly rounded. Juxta elliptical, apico-medially deeply notched. Vesica with three short spine-like cornuti of 82-96 μm.

FEMALE GENITALIA ( FIG. 129 )

Antrum spiculose. Colliculum short, sclerotized. Ductus bursae roughly ¾ X length of corpus bursae, slightly sinuate, medially enlarged, enlarging towards corpus opening on distal ¼. Corpus bursae roughly 1.2 of ductus bursae, large, globular, one half covered with spines, other half reticulate; broad lightly sclerotized signum.

DISTRIBUTION

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

DNA BARCODING

A maximum intraspecific p-distance of 0.7% is found between specimens MFNLEP-PYRALPHIL01-B03 from Luzon (Benguet) and MFNLEP-PYRALPHIL07-H12 from Luzon (Ifugao). Scoparia aenea sp. n. is recovered as sister species to Scoparia ifugaoensis sp. n. in the RaxML tree (BS = 95).

ETYMOLOGY

From the Latin aeneus, a, um, “copper-colored.”
