Paratype: Yunnan: 1♂, Pu’er , 1450 m, 14.VIII.2016, leg. KJ Teng et al., slide No. LiSR17016 .
Diagnosis. The new species can be distinguished from other described species of the genus in the male genitalia by having a papillary uncus, and an aedeagus with two basally joined, strongly hooked apical processes.
Description. Adult ( Fig. 5 View FIGURES 3–8 ). Wingspan 11.0 mm.
Head whitish yellow. Labial palpus whitish yellow, with brown scales on outer surface of first palpomere basally. Antenna yellow except scape dark brown dorsally.
Thorax and tegula yellow except brown at base. Forewing yellow, with yellowish brown scales; costal margin with black spot at base and at basal 3/5; apex with dense dark brown scales forming a diffused apical spot; discal, discocellular and plical stigmata black; fringe dark brown, with a yellow basal line. Hindwing and fringe brown. Legs yellow; on dorsal surface, femur of foreleg black, tibia yellowish brown, tarsus with entire third and fourth tarsomeres dark brown, tibia of midleg black, with yellow streak at middle and apex, tarsus black at middle of first tarsomere and at base of second tarsomere as well as on entire third and fourth tarsomeres; on outer surface, tibia of hindleg black, ringed with yellow at middle and at apex, tarsus black at middle of first tarsomere and at base of second tarsomere as well as on entire third tarsomere.
Male genitalia ( Fig. 17 View FIGURES 15–20 ). Uncus small, papillary. Gnathos with ventral plate short, sub-rectangular; basal arm widely banded. Tegumen arched, almost uniformly wide, inverted V-shaped. Valva narrow at base, slightly broadened to before obtusely rounded apex, with a cluster of setae near base above ventral margin; costa narrowly banded, reaching distal 1/4 of costal margin; transtilla with each arm aequilate in basal 2/3, then widened toward middle, touching each other mesially; sacculus about 1/3 length of valva, sub-triangular, distally produced to a sclerotized process bent inward. Saccus triangular, rounded at apex. Juxta U-shaped, widened anteriorly; lateral lobe uniformly narrow. Aedeagus slightly shorter than valva, inflated medially, with two basally joined, strongly hooked apical processes.
Female unknown.
Distribution. China (Guizhou, Yunnan).
Etymology. The specific epithet is derived from the Latin bi- and hamatilis, referring to the two hooked distal processes of the aedeagus.
