description: <i>Scaeosopha gibbosa</i> Li <i>et</i> Zhang sp. nov. (Figs. 24, 48, 60) <b>Description.</b> Adult (Fig. 24): Wingspan 16.5–19.0 mm. Head with frons white, vertex deep-yellow, scale tuft behind compound eye yellow except black posteriorly. Antenna whitish-yellow except scape black and flagellum ringed with black dorsally. Labial palpus grayish-white, third segment dark-brown in distal half. Thorax whitishyellow, yellow along margin. Tegula grayish-yellow, with black scales on outer and inner margins. Forewing whitish-yellow, overlaid with brown spots and patches, yellow along fold, predominantly brown posteriad of fold; rounded black spot at end of cell; large black patches at base of costal margin and dorsad of fold to tornus; several longitudinal pale-brown streaks along veins from before anterodistal corner to ventrodistal corner along outer margin of cell; terminal line dark-brown; cilia whitish-yellow, mottled black scales on termen. Hindwing and cilia yellowish-brown. Legs dirty whitish-yellow. Male genitalia (Fig. 48): Brachia of uncus broad at base, narrowed to 3/5 where it curved slightly inward; distal 2/5 narrow, elongate elliptical. Valva broad and short, elliptical, with numerous commalike processes on ventral half, ventral margin with fine setae; valvella strong, longer than valva, sparsely setose, dilated distally, apex round, with a setose process from base reaching 2/3 length. Phallus very long, more than three times length of uncus brachium, evenly wide, weakly sclerotized; cornutus absent. Female genitalia (Fig. 60): Posterior apophysis about twice as long as anterior apophysis. Sterigma tubular, parallel sided laterally, posterior margin obliquely truncate. Ductus bursae longer than twice length of anterior apophysis; ductus seminalis arising from about middle of ductus bursae. Corpus bursae large, elongate oval, slightly shorter than ductus bursae; signa a pair of longitudinal sclerotized leaf-shaped plates, about 1/5 length of corpus bursae. <b>Type material.</b> Holotype &amp;male;, <b>BRUNEI</b>: Rampayoh R. [4°29' N, 114°29' E], LP 291B, GR 951801, Lowland dipterocarp forest, 150 ft., 11–15.iv.1988, coll. G. S. Robinson, BM 1988-160, BMNH Microlep. slide no. 31000, Houhun Li (BMNH, London). Paratypes: 4 &amp;male;, 1 &amp;female;, same data as for holotype, BMNH Microlep. slide no. 31001 (&amp;female;), Houhun Li (BMNH, London). <b>Distribution.</b> Brunei. <b>Diagnosis.</b> This new species is similar to <i>S</i>. <i>chionoscia</i> Meyrick in the male genitalia, but can be separated from it by the valva having numerous commalike processes on ventral half and the valvella with a setose process arising from base in the male genitalia; the tubular sterigma obliquely truncate on posterior margin and the signa being a pair of sclerotized longitudinal leaf-shaped plates in the female genitalia. In <i>S. chionoscia</i> Meyrick, the valva has commalike processes throughout the ventral surface and the valvella lacks the process (Fig. 43); the sterigma is cone-shaped and the signa are a pair of fan-shaped plates (Fig. 56). The new species is also similar to <i>S. incantata</i> Meyrick, but can be distinguished by the tegumen being slightly concave on the anterior margin, whereas <i>S. incantata</i> has the margin deeply concave and trianglar (Fig. 44). <b>Etymology.</b> The specific epithet is derived from the Latin <i>gibbosus</i> = gibbous, in reference to the valvella with a setose process in the male genitalia.
