MATERIAL

Lectotype: ♂ (genitalia on slide PyralidaeNHMUK Slide N° 3590). “ Negros I.| 6000 ft. Philippines 1896 | Whitehead ,” “1909-42” ( NHMUK). Lectotype designated by M. Nuss .

Paralectotypes: 5 unsexed, same data ( NHMUK). Nuss mentions that one of them is not conspecific ( Nuss, 1998, p. 489) .

Other specimens examined: 10 ♂, 24 ♀, 35 unsexed (detailed information in Table S1; https://doi.org/10.5061/ dryad.b8gtht7mh) .

DIAGNOSIS

In male genitalia ( Fig. 60 View Figs 58-63 ), the long uncus, the straight, tubular gnathos as well as the patch of minute cornuti on the vesica separate this species from its congeners. The female genitalia ( Fig. 122 View Figs 120-123 ) has a flattened ductus bursae, straight on basal half, with a short loop at midlength, distally wrinkled.

REDESCRIPTION

HABITUS (FIG. 04)

Forewing length 6-8 mm in males (n = 5), 6-9 mm in females (n = 17), ground color greyish white, basal area scattered with white and brown scales. Antemedian dark brown band running from basal ¼ of costa to middle of dorsum; basal edge well-marked, wavy; distal edge fuzzy. Median area marked with white scales. Distal discoidal stigma dark brown. Postmedian and subterminal white lines forming an X. Margin greyish white. Fringes chequered white and grey. Hindwing dirty white.

MALE GENITALIA ( FIG. 60 View Figs 58-63 )

Uncus ¾ X tegumen arm length, distal half ventrally densely setose, apex pointed. Gnathos projection about 2/3 of uncus length, straight, tubular, with apex pointing downwards. Valva dorsal margin convex, sclerotized, ventral process marked, apex rounded. Juxta base rounded, apex conspicuously indented. Vesica with a group of about 30 tiny cornuti.

FEMALE GENITALIA ( FIG. 122 View Figs 120-123 )

Antrum forming a pouch covered with tiny sclerotized spicules. Colliculum about 4.5 X length of tergite VIII, flattened. Ductus bursae as long as colliculum, straight, with one tight loop shortly after colliculum junction, slightly enlarged in distal half before corpus opening. Corpus bursae globular, one half densely covered with spines, the other one reticulate, with one large sclerotized patch.

DISTRIBUTION

PHILIPPINES: Luzon (Benguet, Ifugao, Mountain Province), Mindanao (Davao Oriental), Mindoro (Oriental Mindoro), Negros. Collected at altitudes between 1300 and 2350 m.

DNA BARCODING

The species delimitation analysis recovered six different MOTUs within specimens of S. philippinensis from Luzon (Ifugao, Mountain Province), Negros (one MOTU each), as well as Mindanao and Mindoro (two MOTUs each). Three MOTUs were represented by females only. A maximum intraspecific p-distance of 9.3% is found between samples MFNLEP-PYRALPHIL07-A06 from Mindoro and MFNLEP1179 from Negros.

REMARKS

In Sasaki (1998), male genitalia of S. philippinensis is represented with a glabrous vesica. However, inspection of the genitalia slide from the holotype confirms the presence of the patch of minute cornuti on the vesica.
