MATERIAL

Holotype: ♂ (specimen identifier coll.mfn-berlin.de_u_c6cac, DNA voucher MFNLEP-PYRALPHIL01-D10 , genitalia on slide TL985♂; BOLD sample ID PYPHI035-21, Genbank Accession Number PP196727 ). PHILIPPINES: Luzon, Mountain Province, Chatol , 2100 m, 16-18.11.1997 (K. Ebert, W. Mey, M. Nuss). Deposited in MfN .

Paratypes: 2 ♂ (specimen identifiers coll.mfn-berlin.de_u_e1338d, 9e6b86) (detailed information in Table S1; https://doi.org/10.5061/dryad.b8gtht7mh) .

DIAGNOSIS

In male genitalia ( Fig. 75 ), the vesica devoid of cornuti and the mesal part of the valva without a projection separate this species from other Micraglossa species from continental China (W. Li et al., 2010). From other Philippines species, Micraglossa polisensis sp. n. can be recognized by the bulky uncus apex (in lateral view), the valva gently tapering towards apex, the semi-rounded apex of the valva, and the rounded juxta. Females are not known.

HABITUS ( FIG. 18 )

Forewing length 5.0-5.7 mm (n = 2); ground color cream and brown. Antemedian line white, wavy. Median area mixed with cream and brown scales; one distal discoidal thick brown patch. Postmedian line well marked, S-shaped, running straight down to discal cell, cream. Subterminal line cream, medially incurved inwards, nearly meeting postmedian line there. Fringe cream with black spots. Hindwing dirty white.

MALE GENITALIA ( FIG. 75 )

Uncus ca 9/10 X tegumen arm length, narrowed on distal half, laterally with scattered setae, apex spatulate in dorsal view. Gnathos projection about 9/10 X uncus length, with subapical dorsal tooth pointing upwards, small tip pointing downwards at apex. Valva tapering towards apex, dorsal margin sclerotized, slightly concave, apex semi-rounded. Juxta basally broadly rounded, distally membranous. Phallus straight, vesica without cornuti.

FEMALE GENITALIA

Not known.

DISTRIBUTION

PHILIPPINES: Luzon (Ifugao, Mountain Province). Collected at altitudes between 2000 and 2100 m.

DNA BARCODING

A maximum intraspecific p-distance of 0.2% is found between specimens MFNLEP-PYRALPHIL01-D10 from Mountain Province and MFNLEP-PYRALPHIL01-H01 from Ifugao on Luzon.

ETYMOLOGY

The name is derived from the type locality, Mount Polis, on Luzon island.
