Detailed information in Table S1 .

Diagnosis. Sufetula minuta sp. nov. ( Figure 15 View Figures 15-18 ) is very small (forewing length ¼ 3.6 mm). The costal median spots are very small, flat semicircles accompanied with a dark brown streak. The female genitalia ( Figure 51 View Figures 50-53 ) are unmistakable because of the lack of a discrete signum, the looped and sclerotised ductus bursae, and the remarkably long papillae anales.

Description. Wings ( Figure 15 View Figures 15-18 ). Forewing length: 3.6 mm; narrow, ground colour cream, speckled with dark brown. Antemedian area dark brown. Antemedian line cream, jagged. Costa with three small cream median spots. Median area dark brown on basal half. Median discoidal spot oblong, dark brown. Postmedian line cream, basally edged with dark brown, slightly incurved from costa to medial veins, bent outwards toward marginal emargination, then markedly arched basad from M 3 to dorsum. Subterminal area dark brown. Margin cream. Fringes chequered cream and dark brown. Hindwing brown, medially with two broad cream bands, postmedian area with cream patches. Tympanal organs ( Figure 28 View Figures 27-31 ). ♀. Bullae tympani posterior fourth recessed. Venulae secundae faintly marked, running nearly straight down to tergite II anterior edge. Tympanic depression small, about 1/4 width of bulla, a welldemarcated saccus tympani. Male genitalia. Not known. Female genitalia ( Figure 51 View Figures 50-53 ). Posterior apophyses ca 3.1 × tergite VIII length. Anterior apophyses ca 2.5 × tergite VIII length. Colliculum tubular, weakly sclerotised, ca 1/5 × tergite VIII length. Ductus bursae ca 3.3 × corpus length, anterior 1/3 forming sclerotised loop. Corpus bursae globular, covered with acanthae, anterior half with V-shaped patch of densely packed acanthae, proper signum absent.

Distribution. Known from the Philippines (Palawan, Samar), at elevation between 40 and 390 m ( Figure 55 View Figure 55 ).

Etymology. From the Latin minutus, a, um, “short”, referring to the short size of the species.

DNA barcoding. A maximum intra-specific variation of 7.3% is observed between the specimen MFNLEP-PYRALPHIL11- E 07 from Palawan and the specimen MFNLEP967 from Samar.
