Similar species. Sufetula fulgurata sp. nov., Sufetula elfridea sp. nov.

Diagnosis. In the forewing ( Figures 10, 11 View Figures 9-14 ), the antemedian line is more conspicuously jagged than in Sufetula fulgurata sp. nov. and S. elfridea sp. nov. In the male genitalia, the valva apex is evenly rounded, while it is slightly pointed in Sufetula fulgurata sp. nov. In the female genitalia ( Figure 48 View Figures 46-49 ), the colliculum opens posteriad directly outwards and is square in ventral aspect, while the sclerotised ring observed in Sufetula fulgurata sp. nov. is narrower and does not reach the posterior margin.

Description. Wings ( Figures 10, 11 View Figures 9-14 ). Forewing length: 4.5 - 6.5 mm in both sexes. Male forewing ( Figure 11 View Figures 9-14 ) colour pale yellow speckled with brown. Antemedian line white, edged with dark brown on both sides, jagged in shape, forming two teeth pointing distad. Costa with pale orange streak. Two white patches in median area close to antemedial line: one between teeth of line, other occupying most of dorsal area. Costa with three white triangular spots obliquely pointed towards margin, basally edged with dark brown. Small, round discal spot. Postmedian line white, bordered with dark brown, enlarged at costa; first curved outwards, acutely pointed toward distal margin along medial fold, then mostly straight and oblique to dorsum at 2/3 from base of wing, with one jag directed basad; curved outwards at termen. Forewing female ( Figure 11 View Figures 9-14 ) pale brown, with antemedian, postmedian and subterminal area brown coloured. Marked orange suffusion at costa. Costal spots with a fourth spot near postmedian line. Postmedian line narrower at costa than in male specimens. Forewing CuP vein absent. Tympanal organs ( Figure 25 View Figures 19-26 ). ♀. Bullae tympani with posterior fourth recessed posterior of ramus tympani. Posterior depression shallow, as wide as bulla tympani, with posterior edge not clearly demarcated. Venulae secundae conspicuously marked, slightly incurved, running down to anterior edge of sternum II. Male genitalia ( Figure 37 View Figures 32-37 ). Uncus ca 1/3 of tegumen arm length, narrowed at basal 1/3, apex spatulate. Valva ovate, with apex evenly rounded. Female genitalia ( Figure 48 View Figures 46-49 ). Posterior apophyses 2.5 - 2.7 × tergite VIII length. Anterior apophyses 1.8 - 2 × tergite VIII length, at basal 1/4 with rounded ventral bump. Colliculum opening directly posteriad, tubular, short. Ductus bursae 2.2 - 2.7 × corpus length, slender, straight. Corpus bursae medium-sized, globular; posterior half with erected acanthae. Signum 1/3 of corpus length, forming oval patch of small, sclerotised, tooth-shaped thorns.

Distribution. Known from Luzon (Benguet) at an elevation of 750 m ( Figure 55 View Figure 55 ).

Etymology. From the Latin serratus, a, um, “serrate, saw-toothed”, referring to the serrate antemedian line on the forewing.

DNA barcoding. An intraspecific variation of 0.7% is observed between specimen MFNLEP962 from Zambales (Luzon) and specimen MFNLEP963 from Benguet (Luzon). The nearest nonconspecific neighbour is Sufetula choreutalis (specimen MFNLEP970) from Leyte.
