Diagnosis.

This species is similar to Teliphasa albifusa superficially in the forewing color, but can be distinguished by the gnathos about 2/3 the length of the scaphium and the phallus with two cornuti in the male genitalia. In Teliphasa albifusa , the gnathos is about 3/4 the length of the scaphium, and the phallus has a single cornutus in the male genitalia. Moreover, Teliphasa hamata sp. n., Teliphasa similalbifusa sp. n., and Teliphasa sakishimensis are extremely similar in the male genitalia, and differences between them are stated under Teliphasa similalbifusa sp. n.

Description.

Adult (Fig. 8): Wingspan 32.0-36.0 mm. Head white, suffused with black and pale brown scales. Male labial palpus pale yellow to brownish yellow, suffused with white and black scales; second segment slightly dilated in distal 2/3; third segment short, pointed at apex; female labial palpus with second segment white, mixed with yellowish brown scales on dorsal surface; third segment slender, yellowish brown with black, about 1/5 length of second. Antenna with scape white mottled blackish brown; flagellum alternately grayish brown and blackish brown. Thorax white, with brown scales. Tegula deep brown, with black and a few white scales. Forewing with basal area dark brown, mixed with black scales; median area white, with scattered brown scales; distal area ochreous brown, mixed with black and white scales; costa brown from basal 1/3 to 2/3, mixed with black scales, diffused to above cell, with a white spot near base and raised black scales at its outside, with a second white spot at outside of postmedian line, spreading to below R5; antemedian line black, extending from costal 1/4 obliquely inward to scale tuft near base, then obliquely outward to below 1A+2A, finally obliquely inward to dorsal 1/3; postmedian line black, extending from costal 2/3 obliquely outward to M2, then curved and extending inward along CuA1, forming an angle, finally straight to dorsal 2/3, its inner margin serrated; discal and discocellular spots black, the latter relatively large; terminal line pale yellow, with subrectangular brown or blackish brown spots uniformly placed along its inner side, interrupted by white mixed with brown at veins. Hindwing with basal 2/3 yellowish white, distal 1/3 grayish brown, becoming paler from costa to dorsum; discocellular spot pale grayish brown; cilia of fore- and hind-wings pale yellow, grayish brown to brownish yellow along extension of veins. Legs yellowish brown to blackish brown, mixed with black, brown and a few white scales; tarsi blackish brown, white at apex of each tarsomere. Abdomen white mottled black scales except first segment black.

Male genitalia (Fig. 16). Uncus broad, nearly trapeziform, rounded on posterior margin. Gnathos slender, basal half thicker than distal half, apex obtuse; about 2/3 length of scaphium. Valva subrhombic, with relatively dense setae near costa. Costa elongate triangular, broad basally, gradually narrowed distally, reaching before apex of valva; distal 1/4 obviously thinned, slightly curved inward in a hook. Sacculus narrowly banded, reaching valva apically. Transtilla knotted medially as a semielliptical expansion. Juxta irregular in shape, heavily sclerotized. Saccus separated. Phallus protruding near dorsal 1/2; with two cornuti, one a long plate, serrated along dorsal margin of distal part, another slender, heavily sclerotized, protruding out from phallus near apex, longer than 1/2 length of phallus, curved medially and forming a large hook.

Female genitalia (Fig. 22). Papillae anales subtriangular, densely setose. Eighth tergite nearly rectangular, with sparse setae posteriorly; eighth sternite paired triangular plates. Apophyses anteriores about same length as apophyses posteriores; thicker than apophyses posteriores. Antrum rectangular, heavily sclerotized. Ductus bursae thin, slightly longer than corpus bursae, weakly sclerotized posteriorly, with one horned plate basally. Corpus bursae pyriform; signum nearly rectangular, with clustered spines.

Distribution.

China (Fujian, Guangxi, Yunnan).

Etymology.

The specific name is derived from the Latin hamatus (hooked), referring to the slender hooked cornutus protruding out from the phallus in the male genitalia.
