description: 19. Frisilia cornualis Park, sp. nov.
Type s. HOLOTYPE ♂, Ba Be National Park, Bac Khan Prov., Vietnam (KT Park & MY Chae), gen. prep. no. CIS-5293. PARATYPES. 1♂, 6Ψ, Nantou Co., Hueisien Exp. Forest, 650 m, Taiwan, 24–29 X 1998 (Mey & Spiedel), gen. prep. no. CIS-5300 (♂), CIS-4930 (Ψ). The holotype is deposited in the CIS, and paratypes in the ZMHB.
Diagnosis. The new species is superficially similar to F. trizeugma Wu and Park, but it can be distinguished by the grayish-orange ground color of the forewing, and the almost triangular labial papus with grayish-orange dorsal surface (labial palpus projected anteriorly, and with dark brown dorsal surface, in F. trizeugma).
Description. Male (Fig. 20). Wingspan, 11.0–12.0 mm. Head pale brownish orange dorsally, with vertical furrow centrally. Tegula dark brown anteriorly, but pale grayish brown speckled with brown scales ventro-distally. Antenna pale orange dorso-anteriorly, dark brown ventro-distally; flagellum speckled with blackish scales about at basal 1/10 and apical 2/10, pale orange between them. Labial palpus atypical, more or less triangular; 2nd segment strongly bent with long scale tufts projecting anteriorly, grayish-orange rough scales dorsally; distal portion bent downward, sparsely speckled with dark-brown scales on outer surface apically; 3rd segment minute, concealed in long scale tufts of 2nd. Forewing elongate; ground color grayish orange; dark scales scattered irregularly on upper surface; a small discal spot at middle; a reniform stigma beyond cell; dark-brown scales along costa at basal 1/4; costa nearly straight; apex obtuse; termen slightly oblique, not sinuate. Venation with R3 and R4+5 stalked near middle; R4 and R5 stalked near 3/4; R5 to termen; M1 remote from R3+4 at base; M2 absent; M3 almost parallel to M1; CuA1 and CuA2 stalked at basal 1/4. Hind wing gray; apex sharply pointed; fringe darker at basal half and paler at distal half with dark brown tips; M3 and CuA1 coincident.
Female with some different forewing venation from that of male: R3 and R4+5 stalked near basal 1/5; R4 and R5 stalked near 3/5; R5 to costa.
Male genitalia (Figs. 51, 51 a). Basal lobes of uncus very short. Gnathos moderate, strongly bent preapically. Costal bar broad. Valva broad at base, narrowed beyond middle; costa concave before middle; distal part nearly parallel, slightly concave beyond half on ventral margin, with round apex; sacculus relatively short. Juxta with crescent median plate on ventral surface; lateral lobes not produced. Aedeagus as long as valva, with a pair of heavily sclerotized, horn-shaped, strong cornuti; one very strong, about 2/5 of aedeagus and the other more slender, shorter than the first.
Female genitalia (Fig. 63). Eighth sternite with round caudal margin. Apophyses anteriores about 1/2 length of apophyses posteriores. Antrum weakly sclerotized, cup-shaped, with spinules on inner surface; connected with narrow ductus bursae. Ductus bursae narrowed in conjunction with antrum, then broadened, about 1.5 times length of corpus bursae. Corpus bursae ovate; signum a somewhat peanut-shaped, weakly sclerotized plate with fine thorns on upper surface.
Distribution. Vietnam, Taiwan.
Etymology. The specific name is derived from the Latin "cornu" (= horn), corresponding to the hornshaped cornuti in the aedeagus.
Diagnosis. The species differs from its allies by the relatively broad forewing with golden- yellow ground color.
Adult (Fig. 21, non-type in USNM). Wingspan, 15.0–17.0 mm.
