SIMILAR SPECIES

Glaucocharis kabundukanis sp. n., G. hamulus sp. n.

DIAGNOSIS

Glaucocharis altissima sp. n. is externally similar to G. clytia and G. kabundukanis sp. n. The forewing of G. altissima sp. n. ( Fig. 23 View Figs 16-23 ) shows an ochreous ground color speckled with brown scales, while it is white to yellow and speckled with dark brown scales in G. clytia and white to ochreous in G. kabundukanis sp. n. The male genitalia ( Fig. 80 View Figs 76-81 ) are similar to those of Glaucocharis kabundukanis sp. n.: The costa is projected apically into a slender arm about 1/4 of valva length, while the projection is conspicuously shorter in G. kabundukanis sp. n.; the juxta is deltoid with truncate apex, while it is slender and elongate in G. kabundukanis sp. n. In female genitalia ( Fig. 139 View Figs 136-139 ), the indentation of the antrum posterior margin is less deeply incurved than in G. kabundukanis sp. n., and the basal pouch of the ductus bursae lacks the sclerotization found in G. kabundukanis sp. n.

HABITUS ( FIG. 23 View Figs 16-23 )

Forewing length 6.5 mm (n = 1); ground color light ochreous, medially suffused with brown scales. Antemedian line originating at costal 1/3, arched outwardly, then bent inwards towards dorsum, meeting dorsum at right angles, cream. Basal and median area below costa uniformly suffused with brown scales. Postmedian stigma forming vertical dark brown dash edged distally with cream. Postmedian line originating at costal 3/4, broadly arched outwards, meeting dorsum with an angle of 55°, cream. Subapical Vshaped streak cream. Subterminal area cream, distally suffused with brown. Margin with six black spots, the three near tornus more conspicuously marked. Fringes copper. Hindwing cream.

MALE GENITALIA ( FIG. 80 View Figs 76-81 )

Uncus ca 5/4 of tegumen arm length, slender, regularly curved downwards, apex pointed in lateral view. Gnathos ca 3/4 of uncus length, slender, triangular, apex tip pointed upwards. Tegumen arms slightly angled at distal 1/3. Valva basally with three conspicuous, sclerotized bristles; ventral margin straight; costa conspicuously sclerotized, apically projecting upwards into slender arm ca 1/4 the length of valva; valva apex pointed. Juxta deltoid with truncate apex. Vesica with row of six cornuti (45-70 μm).

FEMALE GENITALIA ( FIG. 139 View Figs 136-139 )

Anterior apophyses 2.2 X length of tergite VIII. Posterior apophyses ca 2.2 X length of tergite VIII. Intersegmental membrane VIII-IX 1.8 X length of tergite VIII. Antrum forming a lightly sclerotized cone with posterior margin ventrally broadly incurved. Ductus bursae 1.5 X length of corpus bursae, roughly straight, larger distally; basal pouch ellipsoid, membranous, with patch of small spicules. Corpus bursae spherical, with one large cross-shaped signum.

DISTRIBUTION

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

DNA BARCODING

Two MOTUs were recovered in the species delimitation analysis for North Luzon and Mindoro. Unfortunately, the MOTU for Mindoro is exclusively represented by female specimens. A high haplotype diversity is recovered, with the 19 specimens sequenced showing 11 different haplotypes (see Fig. 179e View Fig ).

ETYMOLOGY

From the Latin altus, a, um: high and the superlative –issim, referring to the high altitude at which the species is encountered.
